Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Exchanges. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.

Assessment. Gemini publishes an OpenAPI and AsyncAPI contract, API key roles that keep withdrawals off a trading key, a funded sandbox, and an official MCP server whose tools carry read-only and destructive annotations and a confirm gate. Client order ids are not checked for duplicates, there is no SLA, and UK, EEA and Australian accounts closed in April 2026.

From our research 12 facts checked against the vendor's pages
Surface listed
The hosted REST API at api.gemini.com (v1 and v2) as an agent calls it, read from developer.gemini.com, its specs catalogue, llms.txt and agents.md, the gemini/developer-platform repository (shallow clone), status.gemini.com, gemini.com's fee, legal and availability pages and the SEC on 3 November 2026. No account was made, no key minted and no MCP session opened
MCP server
Official. gemini-mcp 1.0.1 in packages/mcp-server of github.com/gemini/developer-platform, stdio, built from source (not on npm), 87 tools in the source where the README says 40+, authenticated by GEMINI_API_KEY and GEMINI_API_SECRET in the client config (public market tools need no key). Not in the official MCP registry. The repository's mcp-plugin manifest names a hosted https://api.gemini.com/mcp that no docs page mentions and that answered no complete response to a GET
Key permissions
One role per key, Trader (default; balances, orders, addresses, history), Fund Manager (withdrawals, approved addresses, bank methods, transfers between accounts; no orders), Auditor (read-only, cannot be combined), Administrator (master keys; create and view accounts). Approved (whitelisted) withdrawal addresses are managed by Fund Manager. Keys are revoked in API Settings. No IP allow-list documented
Rate limits
120 requests a minute public, 600 a minute private, five queued burst requests then HTTP 429 until the rate falls; transfers 1 per 5 seconds and deposit addresses 1 per 2 seconds per subaccount. No Retry-After or backoff guidance. WebSocket limits not documented
Sandbox
exchange.sandbox.gemini.com, api.sandbox.gemini.com, wss://ws.sandbox.gemini.com and docs.sandbox.gemini.com. New accounts get $100,000, 1,000 BTC, 20,000 ETH, BCH, ZEC and LTC; bots trade the book; only Bitcoin testnet deposits and withdrawals; 2FA bypass with the GEMINI-SANDBOX-2FA header and code 9999999
Countries served
The availability page lists the United States and its territories, the Bahamas, Bermuda, BVI, Cayman Islands, Costa Rica, Dominican Republic, Jamaica, Mexico, Panama, St Lucia, St Vincent, Argentina, Brazil, Chile, Ecuador, Peru, Uruguay, 33 European countries, Israel, Singapore, Turkey, Australia, Egypt, Ghana and South Africa, with notices that UK, EEA and Australian accounts closed effective 6 April 2026. The support article on countries answered 403
Fees at the lowest tier
0.600% maker and 1.200% taker on spot under $10,000 of 30-day volume, API fee schedule effective 1 September 2026; derivatives 0.02% maker and 0.07% taker; stablecoin pairs 0.00% and 0.01%
FIX and WebSocket
FIX order entry, market data and drop copy with a dictionary and third-party (on-behalf-of) support, documented under /trading/fix. WebSocket at wss://ws.gemini.com with market data and authenticated order-event streams, described by an AsyncAPI file; legacy v1 and v2 WebSocket APIs are docs-only
Terms on automated trading
The user agreement of 19 February 2026 has no clause on API use, bots or automated trading. No separate API terms were found. The developer site's Build an agent guide sets expectations for agents (least privilege, preview, confirmation at execution)
Errors and idempotency
JSON {result, reason, message} with 53 reasons (InsufficientFunds 406, RateLimit 429, MissingRole 403, Maintenance 503). client_order_id is optional, recommended, 1 to 36 characters, not checked for duplicates. A key with Requires Heartbeat cancels its session's orders after 30 seconds without a request
SDKs
TypeScript @gemini-markets/sdk 0.1.1 (23 September 2026; HMAC, OAuth PKCE, REST and WebSocket, 106 operations across 10 namespaces per the docs) and a Go SDK 0.1.0 (29 August 2026), both Apache-2.0 in the developer-platform repository, plus Python, TypeScript and Go samples and three Claude Code skills
Legal entity
Gemini Trust Company, LLC (NMLS 1518126, New York) for exchange services, Gemini Moonbase, LLC for most US states' user agreement, with UK, Irish, Maltese, Singaporean and Australian affiliates named in the privacy policy. The parent Gemini Space Station, Inc. is a Nevada corporation listed on Nasdaq as GEMI

Strengths

  • Key roles enforce least privilege, since Trader cannot withdraw, Fund Manager cannot trade, Auditor is read-only, and a 403 MissingRole names the role an endpoint needs
  • Official MCP server with readOnlyHint and destructiveHint on every tool, a confirm: true gate on funds-moving tools, untrusted-output framing and redaction of free-text fields
  • OpenAPI 3 and AsyncAPI files, llms.txt, llms-full.txt, agents.md, an agent card and an error-codes page with 53 named reasons
  • A sandbox with the same REST, WebSocket and FIX surfaces, test balances on signup and a documented 2FA bypass for automated tests
  • Fee schedule published per tier without login, and a Statuspage feed with component-level incidents

Weaknesses

  • Client order ids are only recommended to be unique and no duplicate rejection is documented, so a retried order can execute twice
  • No Retry-After, backoff guidance or SLA; 429 continues until the rate drops, and the upcoming-changes page reads "TBD"
  • The MCP server lists 87 tools with no toolset or read-only subset switch, which costs context on every session
  • The hosted MCP address in the repository's plugin manifest is on no docs page and gave no complete answer to a GET
  • Accounts in the United Kingdom, the EEA and Australia closed on 6 April 2026, and the availability page still lists those countries

Before you call it notes for agents

  1. Create a Trader key for order flow and a separate Fund Manager key only if withdrawals are in scope; never combine them, and keep the secret out of prompts and logs
  2. Set a client_order_id per order and look it up with get_order_status before resending after a timeout, because Gemini does not reject duplicates
  3. Start on api.sandbox.gemini.com with the same code; sandbox apps register at once, production OAuth apps wait for Gemini's review
  4. Stay under 1 public and 5 private requests a second; a 429 keeps answering 429 until the rate falls, with no Retry-After to read
  5. Check the person's country against the availability page first; UK, EEA and Australian accounts were closed on 6 April 2026

Ownership Public company (Nasdaq: GEMI)

Researched 3 November 2026 from public pages. Gemini's about page, read 3 November 2026, lists its executives, Cameron Winklevoss (President), Tyler Winklevoss (Chief Executive Officer), Chris Mariadason (Chief Compliance Officer), Jeff Tiller (VP and Chief of Staff), Danijela Stojanovic (Interim CFO) and Kate Freedman (Interim General Counsel). No page we read calls anyone a founder, so the founder flag is left off; press reports describe the Winklevoss twins as the founders, which a later pass can confirm from the S-1. The exchange is run by Gemini Trust Company, LLC; the SEC's submissions record (CIK 2055592) names the parent Gemini Space Station, Inc., Nasdaq GEMI, with an S-1 of 24 July 2025, a 424B4 prospectus of 11 September 2025 and a first 10-Q of 10 November 2025, so the company is public and no shareholders are listed. investors.gemini.com refused our reader (403 on robots.txt) and was not read. No social accounts are attached to individuals because none is linked from a Gemini page we read. Shown for information, not part of the grade yet. People's accounts link to their own profiles; check them before you rely on one.

Notable

  • Gemini runs an official MCP server, gemini-mcp 1.0.1 in packages/mcp-server of github.com/gemini/developer-platform (Apache-2.0), a stdio server built from source with npm run build and run with node dist/index.js. Its source defines 87 tools prefixed gemini_ (market data 13, orders 9, funds 11, account 7, margin 7, staking 5, prediction markets 19, streams 3, alerts 13), where the README says 40+ and the docs tools page lists the categories source
  • Every MCP tool is published with readOnlyHint or destructiveHint, and tools that move funds or cancel orders refuse to run without confirm: true. Tool output is wrapped in <tool-output server="gemini-mcp"> markers the server instructions call untrusted data, control characters and bidi overrides are stripped, and free-text fields such as transfer memos and address labels are replaced with [redacted: ...] (packages/mcp-server/src/tools/index.ts, server.ts and redact.ts, read 2026-11-03)
  • The repository's packages/mcp-plugin manifest points at a hosted server, https://api.gemini.com/mcp over Streamable HTTP. No docs page names that address, the agent card and agents.md don't either, and a plain GET on 3 November 2026 twice returned no complete response, so the hosted route is recorded as the repository's claim (packages/mcp-plugin/mcp.json)
  • Not in the official MCP registry. A search for gemini on 3 November 2026 returned 30 entries, all about Google's Gemini models or unrelated; third-party servers for the exchange exist, such as pipeworx-io/mcp-gemini-crypto, which proxy public market data source
  • The developer site serves llms.txt, llms-full.txt, agents.md, an agent card and an agent skills index, a Build an agent guide that tells agents to restate the product, instrument, action and account and confirm before any mutating call, and a specs catalogue with an OpenAPI 3 file for REST and an AsyncAPI file for WebSocket source
  • Rate limits are 120 requests a minute on public endpoints and 600 a minute on private ones, with a burst of five queued requests and then HTTP 429 until the rate falls, plus per-subaccount limits of one request per 5 seconds on transfers and one per 2 seconds on deposit addresses. No Retry-After header or backoff guidance is documented source
  • A client order id of 1 to 36 characters is recommended per session and echoed back, but Gemini only recommends uniqueness and documents no duplicate rejection, so a retried order can double source
  • The sandbox at exchange.sandbox.gemini.com, api.sandbox.gemini.com and wss://ws.sandbox.gemini.com gives each new account $100,000, 1,000 BTC and other test balances, runs bots against the book, and lets automated tests bypass 2FA with a GEMINI-SANDBOX-2FA=true header and code 9999999 source
  • Gemini's areas-of-availability page lists the United States (all states), 12 other countries and territories in North America, 6 in South America, 33 in Europe, Israel, Singapore, Turkey, Australia, Egypt, Ghana and South Africa, and says all customer accounts in the United Kingdom, the European Economic Area and Australia close effective 6 April 2026, while still listing those countries source
  • The revision history runs from 5 October 2015 to 28 October 2026 and records the removal of the deprecated /v1/feepromos endpoint on 10 September 2026, decimal fields changing from numbers to strings on 7 July 2026 and Balance._timestamp changing type on 10 August 2026. The upcoming-changes page says only "TBD" source
  • The user agreement (19 February 2026) names Gemini Trust Company, LLC for Idaho, Louisiana, New York, Ohio and Texas residents and Gemini Moonbase, LLC for the other states, and has no clause on API use, bots or automated trading. The copyright line names Gemini Space Station, LLC; the SEC lists Gemini Space Station, Inc. (CIK 2055592, Nasdaq GEMI) source
  • status.gemini.com's feed for 10 September to 3 November 2026 lists 25 entries, most of them scheduled trading or FIX upgrades of 15 to 60 minutes with possible order timeouts, deposit delays on single networks, and incorrect perpetual index prices for about 3.5 hours on 15 and 16 October; nothing in the feed is dated between 5 August and 9 September source

Score breakdown methodology v0.7 · October 2026 research run

Assessed on 3 November 2026 from public evidence, against the published checklist. Confidence medium. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

CategoryWeight this runScorePoints
Reliabilitychecked 3 November 2026 16%20 14.6
Read with the hosted lines on the REST API at api.gemini.com. status.gemini.com is a Statuspage site with component history (20). Its Atom feed for 10 September to 3 November 2026 holds 25 entries, mostly scheduled trading and FIX upgrades of 15 to 60 minutes with possible order timeouts, single-network deposit delays, and incorrect perpetual index prices for about 3.5 hours on 15 and 16 October; a 3-hour scheduled eOTC window was planned and outside the core API. Minor only (20). Rate limits with numbers, 120 a minute public and 600 private plus per-endpoint limits (15). 429 is documented but with no Retry-After or backoff guidance, and client order ids are recommended without duplicate rejection, so retries are not safe by contract; the heartbeat cancel is a safety net rather than idempotency (8 of 15). No SLA found (0). Generally available (10). 20 + 20 + 15 + 8 + 0 + 10 = 73.

Schema & documentationchecked 3 November 2026 13%16.2 14.3
OpenAPI 3 for REST (specs/openapi/rest.yaml), AsyncAPI for WebSocket, a prediction-markets OpenAPI file and a specs/index.json catalogue; the MCP server's tools take zod schemas published as JSON Schema (25). llms.txt, llms-full.txt, agents.md, an agent card and an agent skills index (10). Endpoint pages state purpose, the Build an agent guide says what to establish before acting and when to stop, and MCP tool descriptions tell the model when to confirm; the docs don't say when not to use an endpoint (15 of 20). Typed inputs with enums for order types, options and sessions, required fields marked, decimals as strings since 7 July 2026 (12 of 15). Examples throughout, samples in three languages, and an error-codes page with 53 named reasons and their HTTP statuses (14 of 15). A revision history dated from 2015 to 28 October 2026 and versioned paths (v1, v2), but the upcoming-changes page reads "TBD" (12 of 15). 25 + 10 + 15 + 12 + 14 + 12 = 88.
Agent ergonomicschecked 3 November 2026 13%16.2 12.8
Graded on the REST API, with the MCP server noted. Order book depth, trade and candle counts can be limited and symbols filtered; the MCP server lists 87 tools with no toolset or read-only subset switch, so a session that loads it pays for all of them (18 of 25). Timestamps, limit_trades, since and per-symbol filters on history, pagination on prediction-market lists (16 of 20). Errors carry a reason and message an agent can branch on, such as InsufficientFunds, MarketNotOpen and MissingRole, though some messages only say to retry later (16 of 20). client_order_id is echoed back but not checked for duplicates, cancel-all-session-orders and the heartbeat limit damage; the MCP server publishes readOnlyHint and destructiveHint on every tool and gates destructive ones on confirm: true (14 of 20). Few required parameters, sensible defaults, and official TypeScript and Go SDKs (15). 18 + 16 + 16 + 14 + 15 = 79.
Security & authchecked 3 November 2026 14%17.5 13.7
Revocable API keys with one role each (Trader, Fund Manager, Auditor, Administrator), HMAC-SHA384 signing with a nonce, and OAuth 2.0 with scopes, PKCE S256, single-use refresh tokens and RFC 7009 revocation; no IP allow-list documented and no key expiry (28 of 30). Auditor is read-only, a Trader key cannot withdraw, approved withdrawal addresses are a Fund Manager action, and the MCP server refuses funds-moving tools without confirm: true (18 of 20). The MCP server wraps every response in untrusted-output markers, strips control and bidi characters and redacts memos, labels and agreement text; the REST docs say nothing on the subject (13 of 15). Order and transfer history are readable, but no per-key audit log or API access log was found (5 of 15). security.txt with a PGP contact and a bug bounty paying $150 to $20,000, scoped to the sandbox hosts; no certification was read and no public advisory process was found (14 of 20). 28 + 18 + 13 + 5 + 14 = 78.
Payments & pricingchecked 3 November 2026 10%12.5 5.0
No machine payment protocol (0). The API fee schedule is public per tier without login, 0.6% maker and 1.2% taker at the base tier (20). The API is free to call, public market data needs no key, and the sandbox credits test funds with no card (20). A person must sign up in a browser with identity checks, mint a key or approve an OAuth grant, and production OAuth apps wait for Gemini's review (0). 0 + 20 + 20 + 0 = 40.

Thirteen dated entries between 2 September and 28 October 2026 (20). The nine open items on the repository are all pull requests with replies, Dependabot included, and the docs name trading@gemini.com for developer support; no public issue tracker was tested (15 of 25). Not in the official MCP registry, but current official SDKs, TypeScript 0.1.1 of 23 September and Go 0.1.0 of 29 August 2026 (15). CI workflows validate and publish both SDKs and the MCP server has tests; dependencies are current (8 of 10). 30 + 20 + 15 + 15 + 8 = 88.

The editorial half. A closed service under a user agreement that names its entities by state, with the MCP server and SDKs open under Apache-2.0 (18 of 30). The privacy policy of 11 May 2026 names entities and processing countries, ties retention to need without numbers and names provider categories only, with no DPA or subprocessor list found (16 of 30). The revision history records removals and type changes with dates, but the upcoming-changes page is "TBD" and no notice period is stated (8 of 20).

Fix list 19 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Gemini Exchange API. A fix counts at the next check, once it's public.

What we couldn't check

  • Kind http-api. The developer site leads with REST, WebSocket and FIX and the OpenAPI catalogue; the MCP server is one package in the developer-platform repository and the docs' tools page describes it in a paragraph.
  • The MCP server is official, local stdio, 87 tools in the source (13 of them for a native-OS alerts daemon). The repository's mcp-plugin manifest points at a hosted https://api.gemini.com/mcp that no docs page names and that answered no complete response to a plain GET twice; recorded as the repository's claim, not scored as a remote server. No session was opened.
  • unchecked: the support article on supported countries (support.gemini.com answered 403), so countries come from gemini.com/areas-of-availability, which still lists the UK, EEA countries and Australia beside notices that those accounts closed on 6 April 2026. Recorded as an inconsistency, not deducted.
  • unchecked: whether SOC 2 or ISO 27001 reports exist (gemini.com's trust pages were not read, to respect the site's Crawl-delay of 600 seconds), the live MCP tools/list, and the second half of the revision history page.
  • Judgement call, not a deduction. The revision history records decimal fields changing from numbers to strings (7 July 2026), Balance._timestamp changing type (10 August 2026) and the removal of /v1/feepromos (10 September 2026). No notice period is stated and we could not tell whether these broke existing callers without warning.
  • Process note. www.gemini.com/robots.txt sets Crawl-delay 600. Seven pages on that host were read within about an hour, before the delay was weighed; no further gemini.com pages were fetched after that.
  • firstReleased is 5 October 2015, the revision history's first entry ("Initial REST API documentation"). lastRelease is 28 October 2026, the latest revision-history entry.
  • The user agreement names no clause on API use, bots or automated trading, and no separate API terms of service were found on gemini.com or developer.gemini.com.

Probe metrics

Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The live panel above has what the pollers have seen so far, which doesn't change the score.

For the vendor

Is this your product? Link to this page from your own site or README, then tell us where. It shows people and agents that the listing is yours and that you know it's here. It never changes a grade, rank or review.

  1. Add the badge or a link

    <a href="https://www.anchorterminal.com/tools/gemini-exchange">Gemini Exchange API on Anchor Terminal</a>

    It counts on a page on gemini.com or one of its subdomains, or the README at the root of github.com/gemini/developer-platform.

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "gemini-exchange", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
