Gate vs Kraken API

Gate 42

Graded with the hosted lines on the API v4 at api.gateio.ws with the hosted MCP beside it. No status page found (status.gate.com does not resolve, the docs link none), so 0 for the page and 5 for no readable history. Rate limits are published per endpoint group with numbers and fill-ratio rules (15). Every response carries X-Gate-RateLimit-Limit, X-Gate-RateLimit-Requests-Remain and X-Gate-RateLimit-Reset-Timestamp, 429 answers with the label TOO_FAST, and spot orders take a user text identifier, but no retry or idempotency guidance is written down (12 of 15). No SLA (0). API v4 and the MCP endpoints are production surfaces (10). 42.

Kraken API 67

Read with the hosted lines on the spot API. status.kraken.com is a Statuspage site with REST, WebSocket and FIX components (20). The incidents feed read covers 4 September to 3 November 2026. On 30 October spot and derivatives clients could not connect or submit orders across web, mobile, REST, WebSocket and FIX for 59 minutes 39 seconds, rated minor by Kraken; on 28 October some FIX clients were rejected on reconnection for 1 hour 59 minutes while other interfaces worked; the futures engine was degraded for 3 minutes on 13 October. A whole-exchange order outage 21 seconds short of an hour is read as one major (10 of 30). Numeric limits per key by tier and per pair for the matching engine (15). EAPI:Rate limit exceeded and EService:Throttled with a retry timestamp, a client order id and a validate flag on orders, but no Retry-After header (12 of 15). No SLA (0). Generally available (10). 20 + 10 + 15 + 12 + 0 + 10 = 67.

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.

Kraken API 80

Keys with nine named permissions, optional expiry, IP restriction and nonce window, plus an OAuth sign-in from the CLI (authorisation code with PKCE, public client) that mints a no-withdrawal key expiring within 90 days or a read-only key (30). Read-only and no-withdrawal keys, position limits and pair allowlists in account settings, and MCP approval prompts for 33 dangerous tools (18 of 20). The API returns no untrusted content; the CLI docs warn that the feedback tool uploads a local file without approval (10). Keys and their permissions are listed in settings and ledgers record activity, but no per-call log for the operator was found (6 of 15). A valid security.txt, a bug bounty policy page, SECURITY.md and a secure SDLC workflow in the CLI; certifications not read (16 of 20). 30 + 18 + 10 + 6 + 16 = 80.

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.

Kraken API 65

The editorial half. A closed service with clear terms naming regional Payward entities under California law; the CLI is MIT (15 of 30). The privacy notice was not read (5 of 30). The changelog dates deprecations and the terms carry a last-updated date (16 of 20). No subprocessor or data-location statement read (0 of 20). 15 + 5 + 16 + 0 = 36.

Gate 66

Read for the API with the hosted MCP beside it. The MCP is split by endpoint (58 public tools on /mcp, 400 or more on /mcp/exchange, smaller info and news servers) and the local package filters by module and read-only flag, which stands in for toolsets (5 of 25 for the trading server, 10 added back). Pagination by page and limit, from and to timestamps, status filters (15 of 20). Error labels such as INVALID_SIGNATURE, REQUEST_EXPIRED, IP_FORBIDDEN and READ_ONLY name the recovery (15 of 20). The text order identifier makes retries safe; the local server's source sets no readOnlyHint or destructiveHint and the hosted annotations are unread (8 of 20). Three required fields on a spot order, SDKs in seven languages and a CLI (13 of 15). 66.

Kraken API 79

The MCP server loads services with -s, defaults to no live trading, and its 152 tool definitions average about 520 characters; the REST API takes count, limit and pair filters but has no field selection (18 of 25). Cursor pagination on ledgers and trades since 30 September and 6 October 2026, with ofs deprecated (17 of 20). Prefixed error strings such as EOrder:Rate limit exceeded and EAPI:Invalid nonce, and the CLI's error catalogue says which to retry (17 of 20). cl_ord_id and validate on orders, destructive_hint and elicitation on dangerous MCP tools, no idempotency key on REST (16 of 20). An official Rust SDK at 5 stars, a Go module and example clients, HMAC-SHA512 signing with a strict nonce (11 of 15). 18 + 17 + 17 + 16 + 11 = 79.

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.

Kraken API 80

No OpenAPI file was found for the REST API in the docs read; the CLI's agents/tool-catalog.json gives JSON Schema inputs for all 188 commands and the 152 MCP tools (15 of 25). The docs serve Markdown twins such as quickstart.md and the CLI ships llms.txt, AGENTS.md and CONTEXT.md (10). Endpoint pages and guides on order lifecycle, errors and rate limits say what each call does, with less on when not to use one (15 of 20). Enums for order types, time in force and flags, and enums and required fields in the tool catalogue (12 of 15). Python, Node.js and cURL examples, an errors guide and the CLI's error-catalog.json with retry guidance (13 of 15). A changelog of 120 dated entries with deprecations dated (15). 15 + 10 + 15 + 12 + 13 + 15 = 80.

Gate 35

No machine payment protocol (0). The fee page's table loads after login; help centre and learn articles give the VIP 0 spot rates (15 of 20). Market data over REST and the public MCP needs no account and no card (20). A person registers, verifies identity and mints the key or approves the grant in a browser (0). 35.

Kraken API 40

No machine payment protocol (0). Maker and taker fees by tier published without login (20). Public market data, paper trading and the futures demo need no account or card (20). A person signs up, verifies and mints a key or approves the OAuth sign-in (0). 0 + 20 + 20 + 0 = 40.
