## Which one, for what

### Crypto.com Exchange API (D)

Good for: An agent trading spot or perpetuals on Crypto.com through a local MCP server with safety tiers, for a person outside the App's restricted list.

Ahead on:
- Payments & pricing, 40 against 20

Watch for: exchange-docs.crypto.com and the OpenAPI host answered 403 to robots.txt, so rate limits, key permissions, errors and the changelog could not be read

### OKX API (B)

Good for: An agent trading spot, perpetuals, futures or options on a person's OKX account from a local machine, with demo trading to test first and grid or DCA bots through the kit.

Ahead on:
- Reliability, 65 against 50
- Schema & documentation, 73 against 42
- Agent ergonomics, 77 against 50
- Security & auth, 68 against 54
- Maintenance & community, 81 against 29
- Transparency & trust, 62 against 55

Also in its favour:
- Free to start without a card

Watch for: The fee table loads by script and the fee FAQ defers to the logged-in view, so maker and taker rates were not read


## Why the edge

### Maintenance & community: OKX API +52

- Crypto.com Exchange API (29): Read as a closed service with an open CLI. The last change we could date is cdcx-cli v1.2.6 on 18 June 2026, 138 days before the check, with no commit since; the API changelog is unread (10). No three dated releases in the last 90 days (0). Five of six open items on cdcx-cli, all by collaborators or Dependabot since May, have no comment; the Exchange has a support chat and contact@crypto.com (8 of 25). Not in the official MCP registry and no official SDK beyond the CLI (5 of 15). CI tests on three operating systems with clippy and fmt; the npm wrapper's postinstall downloads the binary and two Dependabot bumps are open (6 of 10). 10 + 0 + 8 + 5 + 6 = 29.
- OKX API (81): Read as a closed service with an open-source kit. Changelog entry of 27 October 2026 and kit v1.5.0 on 28 October (30). Changelog entries on 3, 6, 11, 18, 20 and 26 August, 15, 29 and 30 September and 27 October, and kit releases on 20 and 21 August, 1, 7, 14 and 23 September, 19 and 28 October (20). A public changelog, a Telegram community for the kit and GitHub issues whose replies were not read (10 of 15). python-okx is named as the official SDK and the kit is current; the MCP server is not in the official registry (12 of 15). The kit runs CI on push and pull request across Node 18, 20 and 26 with unit tests and coverage (9 of 10). 30 + 20 + 10 + 12 + 9 = 81.

### Schema & documentation: OKX API +31

- Crypto.com Exchange API (42): An OpenAPI spec exists, since cdcx-cli generates its 95 commands and tools from it at run time, but its host (exchange-developer.crypto.com) answered 403 to robots.txt and the spec was not read; the vendor's own tooling is evidence it exists, not of its quality (15 of 25). No llms.txt on crypto.com or the Exchange pages (0). For descriptions, cdcx's tool descriptions come from the spec, which we couldn't read; the Exchange skill documents 52 endpoints in prose (8 of 20). cdcx's README says the tools carry typed parameters and enum validation, a vendor claim not checked against the spec (8 of 15). For examples, the skills and cdcx README carry worked commands, but the API's error codes and response examples sit on the unread host (6 of 15). Versioned path (v1); the API changelog and announcements page could not be read (5 of 15). 15 + 0 + 8 + 8 + 6 + 5 = 42.
- OKX API (73): No OpenAPI file was found in the V5 docs; the kit's tool definitions are typed TypeScript with annotations, and the organisation has an undescribed ai-builder-openapi-md repository we did not read (12 of 25). okx.com/llms.txt exists and links the API and Agent Trade Kit pages, though the V5 docs have no Markdown twins (5 of 10). Each endpoint states its rate limit, rule, parameters and notes (15 of 20). Enums for ordType, tdMode and instType with required flags (12 of 15). Request and response examples per endpoint and an error code list with messages (14 of 15). A dated changelog with an upcoming-changes section that labels breaking changes and dates sunsets (15). 12 + 5 + 15 + 12 + 14 + 15 = 73.

### Agent ergonomics: OKX API +27

- Crypto.com Exchange API (50): Graded on the REST API as an agent calls it, with the MCP server noted. cdcx serves up to 95 tools, more than 30, but the default serves the `market` group alone and groups are enabled one by one, which is a read-only subset switch (5 + 10 = 15). Pagination and output controls for the API are on the unread docs host; cdcx adds `-o json|table|ndjson` (8 of 20). cdcx returns structured JSON errors and the safety gate names what is missing; the API's own error table is unread (8 of 20). cdcx's tiers (mutate needs `acknowledged: true`, dangerous needs `--allow-dangerous`), `--dry-run` and paper trading give safe rehearsal, though no MCP annotations or API idempotency keys were seen (12 of 20). No official SDK beyond the CLI; defaults in cdcx are sensible (7 of 15). 15 + 8 + 8 + 12 + 7 = 50.
- OKX API (77): limit parameters on books, candles and history, and in the kit --modules and --read-only narrow 170 tools to the three default modules; no field selection (17 of 25). after, before and limit cursors on history endpoints (18 of 20). Numeric codes with messages, such as 51020 for an invalid quantity, and the kit returns a structured error block with code, message and endpoint (17 of 20). clOrdId on orders, batch endpoints and a cap of 3 amendments in flight; the kit sets readOnlyHint on query tools but destructiveHint false on order tools and has no idempotency key (13 of 20). python-okx, the CLI and a demo profile, with passphrase and HMAC signing on every private call (12 of 15). 17 + 18 + 17 + 13 + 12 = 77.

### Payments & pricing: Crypto.com Exchange API +20

- Crypto.com Exchange API (40): No machine payment protocol (0). Spot fee tiers published without login, 0.25% maker and 0.50% taker at Level 1 (20). The API is free, public market data needs no key, UAT and paper trading need no money (20). A person must sign up in a browser with identity checks and mint the key (0). 0 + 20 + 20 + 0 = 40.
- OKX API (20): No machine payment protocol (0). The fee table loads by script and the fee FAQ defers to the logged-in view, so no rate was read (0 of 20, unchecked). Public market data and demo trading need no funded account or card (20). A person signs up, verifies and mints a key (0). 0 + 0 + 20 + 0 = 20.

### Reliability: OKX API +15

- Crypto.com Exchange API (50): Read with the hosted lines on the Exchange API at api.crypto.com. status.crypto.com is a Statuspage site with component history (20). Its feed for 18 August to 3 November 2026 has 25 entries; the Exchange is named in two, an 11-minute database upgrade on 18 August and a one-hour balance display issue on 6 October, while the longer disruptions (Android login on 1 and 5 October, card 3DS on 23 September, Main App predictions on 3 November) are App incidents. There is no Exchange API component, so the record may be incomplete. Minor only (20). Rate limits are documented on exchange-docs.crypto.com, which answered 403 to robots.txt and was not read (0, unchecked). 429 handling and client order ids are on the same host (0, unchecked). No SLA found (0). Generally available (10). 20 + 20 + 0 + 0 + 0 + 10 = 50.
- OKX API (65): Read with the hosted lines on the V5 REST API. okx.com/status is OKX's own page with issue descriptions, maintenance notices and deposit and withdrawal status, but no component history or feed (10 of 20). It lists no incident between 5 August and 3 November 2026; its newest entry is from March 2024, and whether every incident reaches the page cannot be told, so read as clean with a doubt (20 of 30). Rate limits per endpoint, per User ID and per sub-account with numbers, and WebSocket limits (15). Error 50011 on a limit, a clOrdId on orders and a cap of 3 amendments in flight, but no Retry-After or backoff guidance found (10 of 15). No SLA (0). Generally available (10). 10 + 20 + 15 + 10 + 0 + 10 = 65.

### Security & auth: OKX API +14

- Crypto.com Exchange API (54): HMAC-SHA256 API keys made with 2FA; IP whitelisting and pre-approved withdrawal addresses per the official skill, and revocation from the Exchange settings. The permission list (read, trade, withdraw) is on the unread docs host, so scopes are recorded from the skills (20 of 30). On least privilege, the App skill's key has no withdrawal permission, the Exchange skill requires user confirmation before a production trade, and cdcx refuses withdrawals and cancel-all without `--allow-dangerous`; nothing on the server side limits order size (14 of 20). The tools return exchange data, not third-party text, but no guidance on untrusted content was found (6 of 15). An account audit trail is not documented where we could read (4 of 15). No security.txt on crypto.com; cdcx has a SECURITY.md with private reporting and a three-day acknowledgement, and the organisation keeps HackerOne policy guidelines; certifications were not read (10 of 20). 20 + 14 + 6 + 4 + 10 = 54.
- OKX API (68): Key, secret and passphrase with Read, Trade and Withdraw permissions, up to 20 bound IPs, revocation in the account, and unbound Trade or Withdraw keys that expire after 14 idle days; no OAuth (28 of 30). Read-only keys, sub-account keys, demo trading, the kit's --read-only flag and its startup check that hides order tools when the key cannot trade, and an API Agreement requiring minimum scope; no confirmation step in the kit (18 of 20). The news and smartmoney modules return third-party text and the docs read give no guidance on treating it as untrusted (5 of 15). An account audit log tool in the kit and usage records for unbound keys in the Security Center, no per-call log (9 of 15). No security.txt; SECURITY.md with security@okx.com and GitHub private advisories; certifications and a bounty not read (8 of 20). 28 + 18 + 5 + 9 + 8 = 68.

## Verdicts

**Crypto.com Exchange API.** Crypto.com is one of two exchanges here with an official MCP server, cdcx-cli, whose 95 generated tools are grouped by service and gated by safety tier. The API docs, OpenAPI file, terms and trading rules refused or hid from our reader, so rate limits, key permissions and the automated-trading clauses are unchecked, and cdcx has no release since June 2026.

**OKX API.** OKX publishes per-endpoint rate limits, Read, Trade and Withdraw key permissions with IP binding, demo trading on the production host, and an MIT MCP server with 170 tools, a read-only flag and a permission check at startup. The fee table and privacy policy were not read, no OpenAPI file was found, and the news tools return third-party text.

## Before you call either

### Crypto.com Exchange API

1. Enable only the service groups the task needs with `cdcx mcp config --enable trade,account` (the default serves `market` alone), and leave `--allow-dangerous` off unless the person asks for withdrawals or cancel-all
2. Rehearse on `--env uat` or `cdcx paper` first; production keys trade real funds, and the skill requires explicit user confirmation before each live order
3. Put the key in CDCX_API_KEY and CDCX_API_SECRET or `~/.config/cdcx/config.toml` at 0600; there is no key flag, and the key should have no withdrawal permission and an IP allow-list
4. Pass `acknowledged: true` on mutate tools and `--dry-run` while testing; read the tool's generated schema before calling, since the docs host is unreadable to agents without a browser
5. Check the person's country against Crypto.com's geo-restriction article and the Exchange terms before trading; New York and about 70 countries are excluded from the App, and the Exchange list was unreadable

### OKX API

1. Start okx-trade-mcp with --profile demo first, then --read-only on a live key; load only the modules the task needs
2. Use a sub-account key with Read and Trade only, bound to the agent's IP; an unbound Trade key expires after 14 idle days
3. Stay under 60 place-order requests per 2 seconds per instrument and at most 3 amendments in flight per order; 50011 means the limit was hit
4. Send a clOrdId on every order and use the structured error block (code, message, endpoint) to diagnose with read-only tools before retrying
5. Call us.okx.com or eea.okx.com for US, Australian and EEA accounts; openapi.okx.com does not serve those regions
