Bitget vs MEXC API

Bitget 83

Read for the API with the MCP server as the agent route. 14 compact tools by default, module filters, a full surface on request and progressive discovery (25). Cursor pagination on CFD order history since 15 October 2026 and limit parameters on lists (15 of 20). Uniform ok or error result shape from the SDK with typed error classes and compact JSON in the text channel (13 of 20). clientOid on orders, dryRun: true on every write, confirm: true gating cancelAll and withdraw, annotations derived from risk level including readOnlyHint, destructiveHint and idempotentHint (18 of 20). Few required fields, official SDKs in five languages plus the TypeScript agent SDK and a CLI (12 of 15). 83.

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.

Bitget 74

The agent SDK ships openapi.yaml with 109 typed UTA v3 operations from which the tools are generated, a machine-readable contract from the vendor's own organisation though not on the docs site (20 of 25). llms.txt in the SDK and MCP repositories; the docs site has none (6 of 10). Intent tools with a discover tool that explains each verb, action and its risk level, and the server's initialize instructions state surface, modules and read-only posture (15 of 20). Typed inputs with enums and required fields from the OpenAPI source (12 of 15). Examples in the quick start and READMEs, a REST error code page in the legacy docs that we did not read in full (9 of 15). Changelog by day with preview notices and effective dates (12 of 15). 74.

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.

Bitget 40

No machine payment protocol (0). Base spot and futures rates are stated in a help article without login, the tier table draws by script (20). Market data needs no key, demo trading costs nothing and no card is asked for at sign-up (20). A person registers, verifies identity and mints the key in a browser (0). 40.

MEXC API 31

No machine payment protocol (0). Fees published without login on MEXC's own fee guide (20 October 2026) and a 2024 announcement, with a separate API futures schedule; the fee page itself is drawn by script (16 of 20). Public market data needs no key or card; trading needs a verified and funded account. Judgement call (15 of 20). A person must sign up in a browser, and futures need identity verification (0). 0 + 16 + 15 + 0 = 31.

Bitget 65

The editorial half. A closed hosted service with clear terms naming BTG Technology Holdings Limited; the toolkit is MIT (15 of 30). The privacy notice names the controller and EEA representative, gives 7-year and up to 10-year retention for compliance and litigation, and names recipients by category only (18 of 30). Deprecations and parameter changes carry effective dates (delta mode deprecated 27 August, symbol and category required from 30 September, snapshot changes with demo and live dates) but no written policy (15 of 20). Recipients by category, transfers under Seychelles law with no locations or provider names (5 of 20). 53.

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.
