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.

Reliability OKX API +20

Binance API 45

Read with the hosted lines on the spot REST API. No status page was found on binance.com or in the API docs (0), so no incident record (5). Rate limits are published as per-endpoint weights with numbers from exchangeInfo, 6,000 request weight a minute, 50 orders per 10 seconds, 160,000 a day and 61,000 raw requests per 5 minutes, and FIX limits per session (15). 429 and 418 carry Retry-After, a 5xx is documented as unknown status to be queried, and orders take a client order id (15). No SLA (0). Generally available (10). 0 + 5 + 15 + 15 + 0 + 10 = 45.

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.

Transparency & trust OKX API +19

Binance API 43

The editorial half. A closed service whose Terms of Use couldn't be read; the docs, connectors, CLI and skills are MIT on GitHub (10 of 30). The privacy notice couldn't be read, so no retention or subprocessor statement was checked; the prohibited-countries list is public and dated (5 of 30). The changelog gives retirement dates for SBE schemas and FIX fields months ahead (16 of 20). No subprocessor or data-location statement read (0 of 20). 10 + 5 + 16 + 0 = 31.

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.

Payments & pricing Binance API +15

Binance API 35

No machine payment protocol (0). A 0.1 per cent standard spot fee is stated in the fee FAQ; the maker and taker table and futures fees load by script and weren't read (15 of 20). Public market data needs no key and the testnet is free with a GitHub login (20). A person signs up, passes Verified Plus verification, deposits and mints a key (0). 0 + 15 + 20 + 0 = 35.

OKX API 20

No machine payment protocol (0). The fee table loads by script and the fee FAQ defers to the logged-in view, so no rate was read (0 of 20, unchecked). Public market data and demo trading need no funded account or card (20). A person signs up, verifies and mints a key (0). 0 + 0 + 20 + 0 = 20.

Schema & documentation Binance API +13

Binance API 86

The docs are Markdown in a public repository with a Postman collection and a Swagger spec, but the spec was last pushed in October 2024 (20 of 25). llms.txt and llms-full.txt on developers.binance.com (10). Each endpoint states its weight, parameters and notes on behaviour, with less on when not to use one (15 of 20). Enums for order types, time in force and symbol filters, required columns in the parameter tables (12 of 15). Request and response examples throughout and an error code list with messages (14 of 15). A dated changelog since 2018 with retirements announced months ahead, such as the 2 September 2026 field removal notified on 2 December 2025 (15). 20 + 10 + 15 + 12 + 14 + 15 = 86.

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.

Verdicts

Binance API

Binance publishes numeric rate limits, a free testnet with FIX, connectors in eight languages and, since late October 2026, a remote MCP server that trades only in a dedicated sub-account with no withdrawal scope. There is no status page, the terms and privacy notice could not be read, and the MCP tool list is not published.

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

Binance API

  1. Read the X-MBX-USED-WEIGHT and X-MBX-ORDER-COUNT headers and stop on 429 for the Retry-After seconds; a 418 ban runs 2 minutes to 3 days
  2. Treat a 5xx on an order as unknown, not failed, and query the order by origClientOrderId before retrying
  3. Use an Ed25519 key with an IP restriction and only the reading and trading permissions; never enable withdrawals for an agent key
  4. Develop on testnet.binance.vision with BINANCE_API_ENV=testnet; it resets about monthly without notice
  5. For the MCP route, the person must fund the Agentic sub-account from the web UI first; the agent cannot move funds in from the main account

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
