Which one, for what

Coinbase Advanced Trade API C

Best for An agent trading a person's or a treasury's Coinbase account with its own key, where the person wants sandbox tests and portfolio scoping.

Ahead on

  • Schema & documentation, 80 against 73
  • Transparency & trust, 67 against 62

Watch for

No REST rate limit numbers found; the old rate-limits page answers 404 and only the WebSocket limit of 8 per second per IP is published

OKX API B

Best for An agent trading spot, perpetuals, futures or options on a person's OKX account from a local machine, with demo trading to test first and grid or DCA bots through the kit.

Ahead on

  • Reliability, 65 against 58
  • Maintenance & community, 81 against 57

Also in its favour

  • Runs on your own machine

Watch for

The fee table loads by script and the fee FAQ defers to the logged-in view, so maker and taker rates were not read

Why the edge

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 OKX API +24

Coinbase Advanced Trade API 57

Read as a closed hosted service. The last change to the API itself is the Global Derivatives gateway and INTX retirement of 1 October 2026, 33 days before this check; the Python SDK's v2.0.0rc1 is from 30 September (20 of 30). Dated changes in 90 days are the 1 October migration and the agents entries of 17 and 21 August, which run through Advanced Trade (12 of 20). A public changelog and a CDP Discord; SDK issues not read (8 of 15). Official Python SDK current, the rest samples (12 of 15). SDK CI not read (5 of 10). 20 + 12 + 8 + 12 + 5 = 57.

OKX API 81

Read as a closed service with an open-source kit. Changelog entry of 27 October 2026 and kit v1.5.0 on 28 October (30). Changelog entries on 3, 6, 11, 18, 20 and 26 August, 15, 29 and 30 September and 27 October, and kit releases on 20 and 21 August, 1, 7, 14 and 23 September, 19 and 28 October (20). A public changelog, a Telegram community for the kit and GitHub issues whose replies were not read (10 of 15). python-okx is named as the official SDK and the kit is current; the MCP server is not in the official registry (12 of 15). The kit runs CI on push and pull request across Node 18, 20 and 26 with unit tests and coverage (9 of 10). 30 + 20 + 10 + 12 + 9 = 81.

Reliability OKX API +7

Coinbase Advanced Trade API 58

Read with the hosted lines. status.coinbase.com is a Statuspage site with Coinbase Advanced Trade, API, US Derivatives and International Derivatives components (20). The incidents feed we could read runs from 16 September to 3 November 2026. In it Advanced Trade was degraded for 25 minutes on 21 September, the website had a 3-minute major on 14 October, converts were down 1 hour 4 minutes on 26 October, and no incident named the API; 5 August to 15 September was beyond the feed, so minor only for the seven weeks read (15 of 30). No REST rate limit with numbers was found; the older rate-limits page answers 404 and llms.txt lists none, while the WebSocket page gives 8 connections and 8 unauthenticated messages per second per IP (5 of 15). Orders take a client_order_id, but no 429 or Retry-After guidance was found for Advanced Trade (8 of 15). No SLA (0). REST and WebSocket are generally available; the Global Derivatives gateway is a month old and not marked beta (10). 20 + 15 + 5 + 8 + 0 + 10 = 58.

OKX API 65

Read with the hosted lines on the V5 REST API. okx.com/status is OKX's own page with issue descriptions, maintenance notices and deposit and withdrawal status, but no component history or feed (10 of 20). It lists no incident between 5 August and 3 November 2026; its newest entry is from March 2024, and whether every incident reaches the page cannot be told, so read as clean with a doubt (20 of 30). Rate limits per endpoint, per User ID and per sub-account with numbers, and WebSocket limits (15). Error 50011 on a limit, a clOrdId on orders and a cap of 3 amendments in flight, but no Retry-After or backoff guidance found (10 of 15). No SLA (0). Generally available (10). 10 + 20 + 15 + 10 + 0 + 10 = 65.

Schema & documentation Coinbase Advanced Trade API +7

Coinbase Advanced Trade API 80

Public OpenAPI 3.1 spec (45 paths, 51 operations) and an AsyncAPI document (25). llms.txt and a Markdown twin of every docs page (10). Every operation has a summary and description, some one line, several with multi-sentence guidance for equities (14 of 20). Enums on product_type, granularity, order_status, time_in_forces, order_types, order_side and sort_by, with defaults (13 of 15). Examples in the docs and the sandbox's simulated errors, but the spec documents only a default error referencing grpc.gateway.runtime.Error, with no 4xx or 429 shapes (8 of 15). Paths carry /api/v3, the CDP changelog is dated, and the INTX retirement was announced with a date, but the spec's info.version is 0.1 and the October gateway change has no changelog entry (10 of 15). 25 + 10 + 14 + 13 + 8 + 10 = 80.

OKX API 73

No OpenAPI file was found in the V5 docs; the kit's tool definitions are typed TypeScript with annotations, and the organisation has an undescribed ai-builder-openapi-md repository we did not read (12 of 25). okx.com/llms.txt exists and links the API and Agent Trade Kit pages, though the V5 docs have no Markdown twins (5 of 10). Each endpoint states its rate limit, rule, parameters and notes (15 of 20). Enums for ordType, tdMode and instType with required flags (12 of 15). Request and response examples per endpoint and an error code list with messages (14 of 15). A dated changelog with an upcoming-changes section that labels breaking changes and dates sunsets (15). 12 + 5 + 15 + 12 + 14 + 15 = 73.

Transparency & trust Coinbase Advanced Trade API +5

Coinbase Advanced Trade API 67

The editorial half. A closed service whose user agreement answered a bot check; the OpenAPI spec is public and the Python SDK is open on GitHub (12 of 30). Privacy facts per the coinbase-cdp-agentkit check of 1 October 2026 (Coinbase, Inc., processing countries, retention tied to need without numbers), not re-read (10 of 30). INTX endpoints retired on 1 October 2026 with a dated notice and a read-only grace period (12 of 20). Processing countries and provider categories per the same earlier check, no subprocessor list (8 of 20). 12 + 10 + 12 + 8 = 42.

OKX API 62

The editorial half. A closed service with terms that name the contracting entities by region and an API Agreement for agents; the kit is MIT (17 of 30). The privacy policy was not read (5 of 30). The changelog dates sunsets and labels breaking changes, such as port 8443 on 31 October and 16 November 2026 (16 of 20). No subprocessor or data-location statement read; the MCP server is local and its npm package runs a postinstall script whose purpose we did not trace (0 of 20). 17 + 5 + 16 + 0 = 38.

Verdicts

Coinbase Advanced Trade API

Advanced Trade has a public OpenAPI spec, keys limited to view, trade or transfer and to one portfolio, and a keyless static sandbox. No REST rate limit is published, the fee schedule, user agreement and country list sit behind a bot check, and an agent that wants an MCP route uses the separate coinbase-mcp listing.

OKX API

OKX publishes per-endpoint rate limits, Read, Trade and Withdraw key permissions with IP binding, demo trading on the production host, and an MIT MCP server with 170 tools, a read-only flag and a permission check at startup. The fee table and privacy policy were not read, no OpenAPI file was found, and the news tools return third-party text.

Before you call either

Coinbase Advanced Trade API

  1. Mint a fresh ES256 JWT for every request; tokens expire after 2 minutes and Ed25519 keys are rejected
  2. Send a unique client_order_id on every order and reuse it on retry so a dropped connection does not place a second order
  3. Develop against api-sandbox.coinbase.com first; its responses are static, so do not read prices or fills from it
  4. Use a key with view only, or trade without transfer, and restrict it to a portfolio funded for the agent
  5. For perpetuals call the Global Derivatives JSON-RPC gateway at drb.coinbase.com; the /intx/* endpoints are retired

OKX API

  1. Start okx-trade-mcp with --profile demo first, then --read-only on a live key; load only the modules the task needs
  2. Use a sub-account key with Read and Trade only, bound to the agent's IP; an unbound Trade key expires after 14 idle days
  3. Stay under 60 place-order requests per 2 seconds per instrument and at most 3 amendments in flight per order; 50011 means the limit was hit
  4. Send a clOrdId on every order and use the structured error block (code, message, endpoint) to diagnose with read-only tools before retrying
  5. Call us.okx.com or eea.okx.com for US, Australian and EEA accounts; openapi.okx.com does not serve those regions
