Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Uniswap Trading API +60

Bitstamp API 28

Read as a closed service. The last dated API change is 28 August 2026, 67 days before the check (20). Only one dated entry in the last 90 days, after 1 July and 12 June (0). No public repository or issue tracker, support pages did not load and support.bitstamp.net did not resolve; a changelog exists (8 of 25). No official SDKs and no MCP registry presence of Bitstamp's own (0). No package to assess (0). 20 + 0 + 8 + 0 + 0 = 28.

Uniswap Trading API 88

Read as a closed hosted service. The newest changelog notice is dated 22 October 2026 (30). Notices of 20 August, 21 September and 22 October 2026, three in 90 days (20). A help form for developer support that says it won't debug integrators' code, and uniswap-ai with 6 open issues and a push on 26 October (14 of 25). Official TypeScript SDKs current (@uniswap/v4-sdk 2.4.4 with provenance) and the uniswap-ai skills, though no client for the API itself; no MCP registry entry (15). Trusted publishing with provenance on npm, CI and lint hooks on uniswap-ai (9 of 10). Total 88.

Schema & documentation Uniswap Trading API +39

Bitstamp API 51

No OpenAPI or other machine-readable contract was found on the API page or elsewhere (0). No llms.txt or Markdown docs (0). The single documentation page describes each endpoint's purpose and parameters, with notes such as the 10-second cache on open orders and the Travel Rule fields, but not when to use one endpoint over another (14 of 20). Parameters are typed with enumerations (margin mode CROSS or ISOLATED, margin multiplier 1 to 25, order types) and required fields marked (11 of 15). Signing examples in Python, Java and C++, and error families with numbered codes and explanations (13 of 15). Version v2 in the path and header, a dated changelog from 7 April 2023 to 28 August 2026, and a 410.001 code for deprecated endpoints, with no stated notice period (13 of 15). 0 + 0 + 14 + 11 + 13 + 13 = 51.

Uniswap Trading API 90

OpenAPI 3.0 file (Token Trading 1.0.0) for the Trading and LP APIs, about 33 paths with x-internal markers on the margin and 4337 operations (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Operation summaries are one line, but the guides say which routing types go to /swap, /order and /plan, when UniswapX quotes are returned and when a 404 means change the request (14 of 20). Enums for routing types, urgency and position statuses, required fields and bounded integers such as limit 1 to 20 (12 of 15). Examples on every guide page and error schemas for 400, 401, 404 and 429 with a stable errorCode enum and per-code retry advice (14 of 15). A /v1 path, a changelog with posted and effective dates and a 30-day minimum sunset policy (15). Total 90.

Reliability Bitstamp API +21

Bitstamp API 63

Read with the hosted lines on the HTTP API v2 at www.bitstamp.net/api/v2/. status.bitstamp.net is a Statuspage site with component history (20). Its feed for 5 August to 3 November 2026 has 17 entries, among them withdrawals failing on 14 networks for about 3 hours on 21 August, database maintenance with login failures and intermittent trading interruptions for about 1 hour 44 minutes on 23 September, a 39-minute halt of all markets on 5 August, and delistings and single-asset suspensions. One major (10). Rate limits with numbers, 400 a second and 10,000 per 10 minutes (15). Limit errors are named (400.002, 400.067, 400.068) but there is no Retry-After or backoff guidance, duplicate client order ids are allowed, and the only retry guidance is to check the order after a 500.016 timeout (8 of 15). No SLA found (0). Generally available (10). 20 + 10 + 15 + 8 + 0 + 10 = 63.

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.

Payments & pricing Uniswap Trading API +20

Bitstamp API 20

No machine payment protocol (0). The fee schedule page loaded empty, the API's fee endpoints need a key, and no rate could be read, so fees are scored as not published (0, unchecked). The API is free, public endpoints need no key and the sandbox needs no money (20). A person must sign up in a browser with identity checks and mint the key (0). 0 + 0 + 20 + 0 = 20.

Uniswap Trading API 40

No machine payment protocol on the API's endpoints; the pay-with-any-token skill lets an agent pay other services' 402 challenges by swapping, which earns nothing here (0). The API is free, stated in the FAQ and the 16 April 2026 post, and integrator fees are capped at 500 bips (20). No card and no plan (20). A person creates an account in the dashboard to get a key (0). Total 40.

Agent ergonomics Uniswap Trading API +14

Bitstamp API 58

Graded on the REST API. Order book grouping and transaction time windows size responses, but there is no field selection and no MCP surface (15 of 25). Offset, limit, since and sort on transaction history, until_id windows on order-data replay (14 of 20). response_code and response_explanation name the failure, such as 400.009 insufficient balance, 403.004 trading blocked and 500.025 insufficient liquidity (16 of 20). No idempotency, since client_order_id duplicates are allowed since November 2023 and the docs say only to check the order id after a timeout; the kill switch limits damage (8 of 20). Few required parameters, but no official SDK in any language (5 of 15). 15 + 14 + 16 + 8 + 5 = 58.

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.

Verdicts

Bitstamp API

Bitstamp documents its v2 API on one static page with numeric rate limits, per-endpoint key permissions, an IP allow-list, a kill switch and a sandbox. There is no official MCP server, duplicate client order ids are allowed, and the fee schedule, terms, privacy policy and country list render by script and could not be read.

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.

Before you call either

Bitstamp API

  1. Mint a key with only the endpoint permissions the task needs and an IP allow-list; keep revoke_all_api_keys in reach as a kill switch
  2. Treat client_order_id as a label, not a guard. On a timeout (500.016) fetch the order by client id before resending, because duplicates are accepted
  3. Use a fresh 36-character nonce and a timestamp within 150 seconds of server time on every request, or expect API0004 and API0017
  4. Stay under 400 requests a second and 10,000 per 10 minutes; 400.002 and 400.067 mean back off, and open-orders answers are cached for 10 seconds
  5. Start on sandbox.bitstamp.net with the same paths, and read the fee schedule in a browser before quoting costs, since it is unreadable to a plain fetch

Uniswap Trading API

  1. 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
  2. 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
  3. Refresh any quote older than 30 seconds before broadcasting, and on 429 pause every request from the key before retrying
  4. Retry unchanged only on UpstreamTimeoutError; NoRouteFoundError and QuoteAmountTooLowError need a different amount, token or protocols list
  5. Send X-Agent-Info with decision_origin: autonomous and keep x-api-key server-side
