## Which one, for what

### Binance API (B)

Good for: An agent trading a funded Binance account outside the prohibited countries, with the deepest set of markets in this group and a free testnet.

Ahead on:
- Schema & documentation, 86 against 60
- Agent ergonomics, 76 against 62
- Security & auth, 72 against 55
- Maintenance & community, 81 against 73

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No status page or incident history found on binance.com or in the API docs

### KuCoin (D)

Good for: An agent trading spot, margin and futures in a person's KuCoin account outside the restricted list, with no sandbox and no MCP server, so through the SDK or raw REST.

Ahead on:
- Transparency & trust, 54 against 43

Watch for: No official MCP server; the registry's `kucoin` entry is a third party's keyless market-data package


## Why the edge

### Schema & documentation: Binance API +26

- 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.
- KuCoin (60): No OpenAPI or other machine-readable contract was found; the docs link a Postman workspace and the universal SDK is generated from an internal spec (8 of 25). No llms.txt; the skills hub ships Markdown SKILL.md files with endpoint tables for seven product areas, read-only (6 of 10). One docs page per endpoint with a description, permission and weight, but no when-to-use guidance (12 of 20). Typed parameter tables with enums for type and side and required flags (11 of 15). Request and response examples per endpoint and a unified six-digit error code scheme introduced with V2 (10 of 15). Dated changelog with V1 to V2 versioning (13 of 15). 60.

### Security & auth: Binance API +17

- 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.
- KuCoin (55): API key with a user-set passphrase, HMAC-SHA256 signing, nine permission groups, IP allow-lists required for Withdrawal and FlexTransfers, trading keys without an IP disabled after 30 days of inactivity, revocation on the management page; no OAuth and no expiry on General keys (24 of 30). A General-only key is a true read-only mode and withdrawals are a separate permission; no confirmation step for writes beyond the key scope (12 of 20). Tools return the exchange's own data (10). The API key info endpoint shows permissions and IP lists; no per-call audit log was found (5 of 15). No security.txt, no disclosure policy or bounty on a page we could read, a whistleblower notice on the legal page (4 of 20). 55.

### Agent ergonomics: Binance API +14

- 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.
- KuCoin (62): Read for the API alone, since there is no MCP server. Responses take limit and cursor parameters on list endpoints and the order book depth is a parameter (14 of 25). Pagination and symbol filters on orders, fills and ledgers (15 of 20). Codes and messages per response, with the V2 scheme claimed to be clearer; the rate-limit page's own examples contradict its table, which costs an agent a turn (12 of 20). clientOid on orders makes retries safe; no MCP annotations to read (10 of 20). Three required fields on a spot order, official SDKs in five languages (11 of 15). 62.

### Transparency & trust: KuCoin +11

- 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.
- KuCoin (54): The editorial half. A closed hosted service with terms that are clear on use, liability and law but name no company (12 of 30). The privacy policy gives retention periods by purpose and provider (2 years after closure, 14 months for Firebase, 3 years for Jumio, 5 years for Sumsub) and names 41 services, with no data centre locations (22 of 30). Endpoints are removed and fields deprecated in dated changelog entries with no notice period or policy (8 of 20). Third parties named by service, locations not stated beyond transfers around the globe (10 of 20). 52.

### Maintenance & community: Binance API +8

- 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.
- KuCoin (73): Read as a closed hosted service. The changelog's newest past entry is 2 November 2026 and the universal SDK was pushed 15 September (30). Nine dated changelog entries since 5 August 2026 (20). A Telegram API group (t.me/KuCoin_API) and api@kucoin.com for limit requests, no public issue tracker for the API; the SDK repository's issues were not checked (10 of 25). Official SDKs current in five languages, no MCP registry presence (13 of 15). No package health signal checked (0 of 10). 73.

## Verdicts

**Binance API.** Binance publishes numeric rate limits, a free testnet with FIX, connectors in eight languages and, since late October 2026, a remote MCP server that trades only in a dedicated sub-account with no withdrawal scope. There is no status page, the terms and privacy notice could not be read, and the MCP tool list is not published.

**KuCoin.** KuCoin publishes pooled rate limits with remaining and reset headers, scoped keys where withdrawals and transfers need an IP allow-list, an official SDK in five languages and read-only agent skills. It runs no MCP server, has no sandbox, status page or OpenAPI file, and its terms name no legal entity.

## Before you call either

### Binance API

1. Read the X-MBX-USED-WEIGHT and X-MBX-ORDER-COUNT headers and stop on 429 for the Retry-After seconds; a 418 ban runs 2 minutes to 3 days
2. Treat a 5xx on an order as unknown, not failed, and query the order by origClientOrderId before retrying
3. Use an Ed25519 key with an IP restriction and only the reading and trading permissions; never enable withdrawals for an agent key
4. Develop on testnet.binance.vision with BINANCE_API_ENV=testnet; it resets about monthly without notice
5. For the MCP route, the person must fund the Agentic sub-account from the web UI first; the agent cannot move funds in from the main account

### KuCoin

1. Mint a key with General only for research; add Spot or Futures only with an IP allow-list, since unbound trading keys are disabled after 30 days of inactivity
2. Send a UUID clientOid on every order and keep it for the retry, and read the order back by clientOid before placing again
3. Budget requests by weight against gw-ratelimit-remaining and sleep for gw-ratelimit-reset milliseconds on 429000; sub-accounts share the pool
4. There is no sandbox, so rehearse with the smallest order size on a dedicated sub-account
5. Use the UTA V2 endpoints and hosts; the Classic API loses endpoints without notice, as the margin credit endpoints did on 21 October 2026
