Gate vs MEXC API

Gate 49

The editorial half. A closed hosted service with a clear user agreement that names no company; the MCP packages are MIT (12 of 30). The privacy policy names a DPO address and categories of recipients, with no retention numbers and no named subprocessors (12 of 30). The changelog records breaking changes such as the amend endpoint path move of 16 October 2026 with no notice period or policy (8 of 20). Transfers outside the user's jurisdiction are disclosed with no locations or provider names (5 of 20). 37.

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.

Gate 70

No public OpenAPI file was found, though the SDKs are generated and the MCP tools carry typed parameters per the tool reference; the hosted tools' JSON Schema could not be read without a session (12 of 25). The whole REST and WebSocket documentation is downloadable as Markdown and the agent guide is a plain page (10). The tool reference gives one line and the main parameters per tool, the API reference a description per endpoint, no when-not-to-use guidance (12 of 20). Required flags, enums for side, type and time_in_force (11 of 15). Examples per endpoint and a labelled error body with a fixed label list the docs tell you to branch on instead of messages (13 of 15). A versioned changelog, v4.106.177 on 2 November 2026 (12 of 15, since entries are terse). 70.

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.

Gate 60

Gate OAuth 2 for the hosted trading MCP with eight scopes per the protected-resource metadata and revocation on the API management page, and API keys with disabled, read-only or read-write per product group, a separate withdrawal group and an IP allow-list of 20 addresses (30). A read-only key and a GATE_READONLY switch exist, and the guide says fund-moving actions need the person's confirmation in the client, with no server-side cap documented (15 of 20). The news and info servers return third-party content with no guidance on treating it as untrusted (5 of 15). Key changes and OAuth grants are visible on the API management page; no per-call log found (5 of 15). No security.txt, no disclosure policy or bounty on a page we read, a proof-of-reserves repository (5 of 20). 60.

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.
