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.\n- Uniswap Trading API (42): Read with the hosted lines on the Trading API. status.uniswap.org redirects to the swap app and the docs link no status page (0). No readable history (5). Rate limit documented as 6 requests a second per key (15). The errors page says to pause all requests from the key on 429, retry 500 and 503 with backoff and refresh quotes after 30 seconds; swaps are signed transactions, so idempotency rests on the chain nonce (12 of 15). No SLA (0). The API is generally available; Guidestar routing is a beta notice (10). 0 + 5 + 15 + 12 + 0 + 10 = 42.\n\n### Transparency \u0026 trust: Gemini Exchange API +20\n\n- 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.\n- Uniswap Trading API (55): The editorial half. The API is closed under API Terms of Use that answered 403; the SDKs and uniswap-ai are MIT and the protocol contracts are open source (15 of 30). No privacy policy read (app.uniswap.org draws by script) and nothing in the docs on retention of quotes or wallet addresses (0 of 30). A published sunset policy of at least 30 days, ideally 60, with dated notices such as the Universal Router 2.0 and 2.1.1 sunset of 21 October 2026 (20). No subprocessors or data locations (0 of 20). Total 35.\n\n### Security \u0026 auth: Gemini Exchange API +15\n\n- 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.\n- Uniswap Trading API (63): A single `x-api-key` header, no scopes, no IP allow-list; revocation and rotation happen in a dashboard robots.txt disallows, so unchecked; nothing in a URL (18 of 30). The API never holds keys or funds, every value transfer needs the caller's signature on `permitData` and the transaction, and the swapper sets slippage (16 of 20). The API returns routes and token lists, not untrusted content (10). The dashboard presumably shows key usage; not read, and no per-call log is documented (5 of 15). security.txt on app.uniswap.org with a Cantina bounty and security@uniswap.org, protocol audits in the docs; no SOC 2 or disclosure timeline read (14 of 20). Total 63.\n\n### Agent ergonomics: Gemini Exchange API +7\n\n- 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.\n- Uniswap Trading API (72): An API, read for response sizing. Quotes and calldata are compact and `/tokens` takes a limit; the quote can carry the swap calldata to save a call (20 of 25). `GET /orders` and `GET /swaps` poll status by id, `/swappable_tokens` and `/tokens` filter by chain and sort, with little pagination elsewhere (12 of 20). Stable `errorCode` values with a `detail` string and a `requestId`, and the docs say which codes to retry (18 of 20). No idempotency key; a swap is a signed transaction whose nonce prevents a double spend, and the docs warn about nonce collisions with pending transactions (12 of 20). Few required fields on `/quote`, defaults for slippage and urgency, but no official client library for the API and signing needs ethers.js, viem or web3.js (10 of 15). Total 72.\n\n## Score by category\n\n| Category | Weight | Gemini Exchange API | Uniswap Trading API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 73 | 42 | Gemini Exchange API +31 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 88 | 90 | Uniswap Trading API +2 |\n| Agent ergonomics | 13% (16.2 this run) | 79 | 72 | Gemini Exchange API +7 |\n| Security \u0026 auth | 14% (17.5 this run) | 78 | 63 | Gemini Exchange API +15 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 40 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 88 | 88 | even |\n| Transparency \u0026 trust | 7% (8.8 this run) | 75 | 55 | Gemini Exchange API +20 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **74.6 · BB** | **63.3 · B** | |\n\n## Facts side by side\n\n| Fact | Gemini Exchange API | Uniswap Trading API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Gemini Trust Company, LLC | Uniswap Labs |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | stdio | |\n| Auth | OAuth or key | API key |\n| Pricing | Pay per use | Free |\n| x402 | no | no |\n| Licence | Proprietary hosted API under Gemini's user agreement.

Client order ids are not checked for duplicates, there is no SLA, and UK, EEA and Australian accounts closed in April 2026.\n\n**Uniswap Trading API.** The Trading API is free, documented by an OpenAPI file with stable error codes, holds no keys since the caller signs every swap, and posts sunset notices 30 days ahead. There is no official MCP server, status page or sandbox, the key is a plain header secret at 6 requests a second, and the API terms refused our reader.\n\n## Before you call either\n\n### Gemini Exchange API\n\n1. 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\n2. 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\n3. Start on api.sandbox.gemini.com with the same code; sandbox apps register at once, production OAuth apps wait for Gemini's review\n4. 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\n5. Check the person's country against the availability page first; UK, EEA and Australian accounts were closed on 6 April 2026\n\n### Uniswap Trading API\n\n1. Call `/check_approval` first, then `/quote`; if `permitData` is non-null sign it as EIP-712 and send `signature` and `permitData` together to `/swap` or `/order`, never one without the other\n2. Route on the quote's `routing`: `CLASSIC`, `WRAP`, `UNWRAP` and `BRIDGE` go to `/swap`, `DUTCH_V2`, `DUTCH_V3` and `PRIORITY` to `/order`, `CHAINED` to `/plan`\n3. Refresh any quote older than 30 seconds before broadcasting, and on 429 pause every request from the key before retrying\n4. Retry unchanged only on `UpstreamTimeoutError`; `NoRouteFoundError` and `QuoteAmountTooLowError` need a different amount, token or `protocols` list\n5. Send `X-Agent-Info` with `decision_origin: autonomous` and keep `x-api-key` server-side\n\n## Questions\n\n### Which is better for AI agents, Gemini Exchange API or Uniswap Trading API?\n\nGemini Exchange API scores 74.6 (BB) on agent readiness against Uniswap Trading API's 63.3 (B), and leads in 4 of 7 scored categories.\n\n### Do Gemini Exchange API and Uniswap Trading API need an API key?\n\nGemini Exchange API takes an API key or an OAuth sign-in.
