## Which one, for what

### Gate (C)

Good for: An agent trading spot, futures and earn products in a person's Gate account outside the 35 restricted locations, with a keyless MCP for research and an OAuth MCP or scoped key for trading.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page, incident history or SLA; the terms give no uptime guarantee and cap liability at three months of fees

### Gemini Exchange API (BB)

Good for: An agent trading spot, perpetuals or prediction markets for a US customer with a role-limited key and a sandbox to rehearse on.

Ahead on:
- Reliability, 73 against 42
- Schema & documentation, 88 against 70
- Agent ergonomics, 79 against 66
- Security & auth, 78 against 60
- Payments & pricing, 40 against 35
- Maintenance & community, 88 against 77
- Transparency & trust, 75 against 49

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: Client order ids are only recommended to be unique and no duplicate rejection is documented, so a retried order can execute twice


## Why the edge

### Reliability: Gemini Exchange API +31

- Gate (42): Graded with the hosted lines on the API v4 at api.gateio.ws with the hosted MCP beside it. No status page found (status.gate.com does not resolve, the docs link none), so 0 for the page and 5 for no readable history. Rate limits are published per endpoint group with numbers and fill-ratio rules (15). Every response carries X-Gate-RateLimit-Limit, X-Gate-RateLimit-Requests-Remain and X-Gate-RateLimit-Reset-Timestamp, 429 answers with the label TOO_FAST, and spot orders take a user `text` identifier, but no retry or idempotency guidance is written down (12 of 15). No SLA (0). API v4 and the MCP endpoints are production surfaces (10). 42.
- Gemini Exchange API (73): 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.

### Transparency & trust: Gemini Exchange API +26

- Gate (49): The editorial half. A closed hosted service with a clear user agreement that names no company; the MCP packages are MIT (12 of 30). The privacy policy names a DPO address and categories of recipients, with no retention numbers and no named subprocessors (12 of 30). The changelog records breaking changes such as the amend endpoint path move of 16 October 2026 with no notice period or policy (8 of 20). Transfers outside the user's jurisdiction are disclosed with no locations or provider names (5 of 20). 37.
- Gemini Exchange API (75): 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). Processing countries are named (US, Ireland, UK, Malta, Singapore, Australia) and providers by category, with no named subprocessors (12 of 20). 18 + 16 + 8 + 12 = 54.

### Schema & documentation: Gemini Exchange API +18

- Gate (70): No public OpenAPI file was found, though the SDKs are generated and the MCP tools carry typed parameters per the tool reference; the hosted tools' JSON Schema could not be read without a session (12 of 25). The whole REST and WebSocket documentation is downloadable as Markdown and the agent guide is a plain page (10). The tool reference gives one line and the main parameters per tool, the API reference a description per endpoint, no when-not-to-use guidance (12 of 20). Required flags, enums for side, type and time_in_force (11 of 15). Examples per endpoint and a labelled error body with a fixed label list the docs tell you to branch on instead of messages (13 of 15). A versioned changelog, v4.106.177 on 2 November 2026 (12 of 15, since entries are terse). 70.
- Gemini Exchange API (88): 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.

### Security & auth: Gemini Exchange API +18

- Gate (60): Gate OAuth 2 for the hosted trading MCP with eight scopes per the protected-resource metadata and revocation on the API management page, and API keys with disabled, read-only or read-write per product group, a separate withdrawal group and an IP allow-list of 20 addresses (30). A read-only key and a GATE_READONLY switch exist, and the guide says fund-moving actions need the person's confirmation in the client, with no server-side cap documented (15 of 20). The news and info servers return third-party content with no guidance on treating it as untrusted (5 of 15). Key changes and OAuth grants are visible on the API management page; no per-call log found (5 of 15). No security.txt, no disclosure policy or bounty on a page we read, a proof-of-reserves repository (5 of 20). 60.
- Gemini Exchange API (78): 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.

### Agent ergonomics: Gemini Exchange API +13

- Gate (66): Read for the API with the hosted MCP beside it. The MCP is split by endpoint (58 public tools on /mcp, 400 or more on /mcp/exchange, smaller info and news servers) and the local package filters by module and read-only flag, which stands in for toolsets (5 of 25 for the trading server, 10 added back). Pagination by page and limit, from and to timestamps, status filters (15 of 20). Error labels such as INVALID_SIGNATURE, REQUEST_EXPIRED, IP_FORBIDDEN and READ_ONLY name the recovery (15 of 20). The `text` order identifier makes retries safe; the local server's source sets no readOnlyHint or destructiveHint and the hosted annotations are unread (8 of 20). Three required fields on a spot order, SDKs in seven languages and a CLI (13 of 15). 66.
- Gemini Exchange API (79): 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.

### Maintenance & community: Gemini Exchange API +11

- Gate (77): Read as a hosted service with open-source MCP packages. The API changelog's latest entry is 2 November 2026 and gate-skills was pushed 3 November (30). 40 dated changelog entries since 5 August 2026 (20). developer@gate.com, a help centre and issue trackers on gate-mcp and gate-skills, replies not checked (12 of 25). In the official MCP registry under io.github.gateio-dev, a GitHub namespace rather than gate.com, and official SDKs current (10 of 15). The local package has a publish workflow and no test workflow in CI, and its last tag is 16 April 2026 (5 of 10). 77.
- Gemini Exchange API (88): Read as a closed hosted service with an open repository. The revision history's latest entry is 28 October 2026 and the repository was pushed on 5 October (30). 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.

## Verdicts

**Gate.** Gate runs official hosted MCP servers with keyless market data and OAuth-scoped trading, a local stdio server with a read-only switch, per-endpoint rate limits with headers and a futures testnet. There is no status page, SLA or OpenAPI file, the fee table needs a login, the MCP host is a separate domain, and the terms name no company.

**Gemini Exchange API.** 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.

## Before you call either

### Gate

1. Start on https://api.gatemcp.ai/mcp for prices and order books with no credential; switch to /mcp/exchange only when the person has approved the OAuth grant with the narrowest scopes
2. For a key-based route, create a key on a dedicated sub-account with read-only on every group but the one the task needs, withdrawal disabled and an IP allow-list; changes take up to 5 minutes
3. Put a unique `text` value starting with t- on every spot order and reuse it on the retry; read the order back before placing again
4. Read X-Gate-RateLimit-Requests-Remain and stop at zero; spot order placement is capped at 10 a second and withdrawals at 1 per 3 seconds
5. Rehearse futures logic on api-testnet.gateapi.io with TestNet keys; there is no spot testnet

### Gemini Exchange API

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
