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.

Schema & documentation Binance API +22

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.

Bithumb Open API 64

No OpenAPI found; the reference is a readme.io site with Markdown twins, and the MCP tool schemas weren't read since the server's source isn't published (5 of 25). llms.txt on apidocs.bithumb.com (10). Reference pages state purpose and the skills say when to use each module and when not to (15 of 20). Typed parameters with enums for side, order type and time in force (10 of 15). Examples in several languages and an error-code page with names, statuses and meanings (12 of 15). Versions per endpoint (v1, v2, v2.1.5) and notices with effective dates (12 of 15). 5 + 10 + 15 + 10 + 12 + 12 = 64.

Payments & pricing Binance API +20

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.

Bithumb Open API 15

No machine payment protocol (0). The fee page timed out on every attempt, so no price is recorded (0 of 20, unchecked). Public market data needs no key, card or account; trading needs a verified Korean account. Judgement call (15 of 20). A person must sign up, pass identity checks and issue keys in the browser (0). 0 + 0 + 15 + 0 = 15.

Security & auth Binance API +12

Binance API 72

API keys with HMAC, RSA or Ed25519 signatures, permissions for reading, trading, futures and withdrawals, an IP restriction, revocation in API Management, and OAuth with four scopes on the MCP server; no key expiry found (28 of 30). Read-only keys, sub-accounts, withdrawals only with an IP restriction, and the MCP server's isolated Agentic sub-account with no withdrawal scope and confirmation before writes (18 of 20). The API returns no untrusted content (10). Keys are listed in API Management and used weight is returned per call, but no per-call log for the operator was found (6 of 15). security.txt with a contact and no expiry, a Bugcrowd programme named in the proof-of-solvency repository, no certification read (10 of 20). 28 + 18 + 10 + 6 + 10 = 72.

Bithumb Open API 60

Keys scoped to chosen permissions, mandatory registered IPs, one-year expiry, a JWT per request and a key-list endpoint with expiry (26 of 30). Read-only keys, --read-only on the MCP server, per-profile read_only on the CLI, a second factor on KRW deposits and withdrawals, and skills that refuse to switch profiles to bypass read-only; nothing server-side confirms an order (16 of 20). The API returns exchange data and the disclaimer warns about prompt injection through third-party plugins (11 of 15). A local audit log for CLI and MCP calls and a key-list endpoint; no server-side per-call log (7 of 15). security.txt timed out and no disclosure policy, bug bounty or certification was found (0 of 20, security.txt unchecked). 26 + 16 + 11 + 7 + 0 = 60.

Maintenance & community Binance API +12

Binance API 81

Read as a closed service. The spot changelog's newest entry is 30 October 2026, the MCP docs are dated 30 October and binance-cli v2.2.0 shipped on 20 October (30).

The MCP package depends only on @modelcontextprotocol/sdk ^1.26 on Node 18, with no public source or CI (5 of 10). 30 + 20 + 9 + 5 + 5 = 69.

Reliability Binance API +11

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.

Bithumb Open API 34

Read with the hosted lines. No status page found on apidocs.bithumb.com or in llms.txt; wallet-status and notices endpoints stand in (0). No readable incident history, though two notices record a public WebSocket interruption and a brief service break (5). Rate limits documented per category with numbers, updated 27 October 2026 (15). A breach is described only as a temporary restriction, with no status code, header or Retry-After, and no client order id or idempotency key is documented; 422 order_not_ready and 500 server_error say to retry later (4 of 15). No SLA found (0). The API is generally available; the MCP server and CLI are at 0.8.5 (10). 0 + 5 + 15 + 4 + 0 + 10 = 34.

Agent ergonomics Binance API +9

Binance API 76

limit on depth, trades and klines, a symbols filter on exchangeInfo and tickers, and SBE encoding, though fields cannot be selected (16 of 25). fromId, startTime, endTime and limit on history endpoints (16 of 20). Error codes with messages an agent can branch on, such as the rate limit and timestamp errors (17 of 20). newClientOrderId on orders, a cancel-replace endpoint and the 5xx unknown-status rule, but no idempotency key on other writes (12 of 20). Connectors in nine languages, a CLI with testnet and demo profiles, and a timestamped HMAC or Ed25519 signature on every private call (15). 16 + 16 + 17 + 12 + 15 = 76.

Bithumb Open API 67

Graded on the REST API with the MCP server. 41 tools in all, selectable by module, so 15 for 11 to 30 or more and 8 added back for the module switch (23 of 25). Candle counts, order paging and a 200-market cap on the ticker (13 of 20). Stable error.name values with retry guidance for order_not_ready and server_error (14 of 20). No client order id or idempotency key documented; the CLI's per-profile read-only flag, the MCP --read-only flag and the skills' read-only gate help, and readOnlyHint annotations weren't checked (9 of 20). Few required parameters, but no official SDK beyond the CLI and a CCXT guide (8 of 15). 23 + 13 + 14 + 9 + 8 = 67.

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.

Bithumb Open API

Bithumb runs an official local MCP server with 41 tools, module selection and a read-only flag, beside a CLI with per-profile read-only gating and six agent skills, over an API with scoped one-year keys and a mandatory IP list. There is no sandbox, no status page, no documented 429 behaviour, and the fees and terms couldn't be read.

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

Bithumb Open API

  1. Ask for a key with asset and order inquiry plus order placement only, never withdrawals, with your IP registered; keys expire after one year and a wrong IP answers 401 NotAllowIP
  2. Start the server with --modules market,account,trade --read-only for analysis and drop --read-only only when the person asks to trade; deposit and withdraw modules stay off
  3. Prefer the bithumb CLI for writes, as the skills do, and check bithumb config show --json for a read-only profile before any order
  4. Keep the ticker's markets parameter at 200 or fewer, batch orders at 30 and cancels at 30 per request, and stay under 140 private calls a second per category
  5. Retry 422 order_not_ready and 500 server_error after a pause; there is no sandbox, so start with the smallest order the market allows
