Binance API vs MEXC API

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.

MEXC API 64

No OpenAPI found; a Postman collection and the CLI's 25 capability reference files are the nearest machine-readable contract (5 of 25). llms.txt on mexc.com, written for assistants and pointing at the API docs and legal pages (7 of 10). Per-endpoint pages with purpose, parameters and permissions, without when-not-to-use guidance (13 of 20). Typed parameters with enums for order types, statuses and intervals (11 of 15). Examples on each endpoint and a separate error-code page with numeric codes and messages (13 of 15). Versioned API (v3) with a dated changelog of 72 entries to 23 October 2026 (15). 5 + 7 + 13 + 11 + 13 + 15 = 64.

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.

MEXC API 58

The editorial half. A closed service with a dated user agreement naming MEXC (Comoros) Ltd; the CLI is UNLICENSED on npm (15 of 30). The privacy policy names no entity, states no retention periods and relies on standard contractual clauses for transfers (10 of 30). The changelog flags endpoints as "will be discontinued soon" without dates and the futures log records removals (8 of 20). Third parties are named by category only, with no subprocessor list or data locations (5 of 20). 15 + 10 + 8 + 5 = 38.

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.

MEXC API 64

Graded on the REST API with the CLI's MCP mode. Responses take limit parameters and the MCP read-only market subset is 22 tools, but a full spot MCP category lists 123 tools (15 of 25). startTime, endTime and limit on history, symbol filters on open orders (14 of 20). Numeric codes with messages, a 30035 order-limit code added 23 October 2026, 5xx guidance (14 of 20). newClientOrderId is optional with no idempotency guarantee; the CLI adds --dry-run and a confirmation step (10 of 20). Few required parameters; SDKs in five languages whose repository was last pushed in February 2024 (11 of 15). 15 + 14 + 14 + 10 + 11 = 64.

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.

MEXC API 65

Granular permissions (account read, trade, withdraw, transfer), per-pair restriction, up to 10 linked IPs, 90-day expiry without an IP, renewal and revocation in the account, 30 keys per account (26 of 30). A read-only MCP mode that hides write tools, a confirmation step before orders and transfers in the CLI and MCP, and --yes that agents are told not to add; nothing server-side confirms an API order (17 of 20). The API returns exchange data, and the CLI security page warns that agents may be led by web pages or files into unwanted actions (12 of 15). CLI confirmations are logged and reported to MEXC with no operator access described; an apiKeyInfo endpoint shows key settings (6 of 15). No security.txt, disclosure policy or bug bounty found; a proof-of-reserves page exists (4 of 20). 26 + 17 + 12 + 6 + 4 = 65.

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). Changelog entries on 2 September, 18 September, 27 October and 30 October (20). A public changelog, connectors pushed in October and a Skills Hub merging pull requests weekly; issue replies not read (10 of 15). Official connectors in nine languages current as of October 2026; the MCP server is not in the official registry (15). Connector CI not read; the CLI publishes release installers (6 of 10). 30 + 20 + 10 + 15 + 6 = 81.

MEXC API 75

Read as a closed service. Last dated change 23 October 2026 in both the spot and futures logs (30). Spot entries on 14 August, 24 August, 11 September and 23 October 2026, futures on 1 September, 11 September, 19 October and 23 October (20). An API support Telegram group, a ticket form and dated changelogs; GitHub issues not read (10 of 15). The official SDK repository was last pushed in February 2024 while the CLI is current (10 of 15). The CLI ships platform binaries with no dependencies and no public repository or CI; the SDK is stale (5 of 10). 30 + 20 + 10 + 10 + 5 = 75.
