## 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 80

Also in its favour:
- A hosted endpoint, with nothing to install

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

### Kraken API (BB)

Good for: An agent that trades spot, xStocks, forex or futures on a person's Kraken account from a local machine, with paper trading to test first and an approval gate on live orders.

Ahead on:
- Reliability, 67 against 45
- Security & auth, 80 against 72
- Payments & pricing, 40 against 35
- Transparency & trust, 65 against 43

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: No self-service spot sandbox; the spot UAT environment is on request through an account manager, and paper trading lives in the CLI


## Why the edge

### Reliability: Kraken API +22

- Binance API (45): Read with the hosted lines on the spot REST API. No status page was found on binance.com or in the API docs (0), so no incident record (5). Rate limits are published as per-endpoint weights with numbers from exchangeInfo, 6,000 request weight a minute, 50 orders per 10 seconds, 160,000 a day and 61,000 raw requests per 5 minutes, and FIX limits per session (15). 429 and 418 carry Retry-After, a 5xx is documented as unknown status to be queried, and orders take a client order id (15). No SLA (0). Generally available (10). 0 + 5 + 15 + 15 + 0 + 10 = 45.
- 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.

### Transparency & trust: Kraken API +22

- 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.
- 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.

### Security & auth: Kraken API +8

- 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.
- 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.

### Schema & documentation: Binance API +6

- 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.
- 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.

### Payments & pricing: Kraken API +5

- Binance API (35): No machine payment protocol (0). A 0.1 per cent standard spot fee is stated in the fee FAQ; the maker and taker table and futures fees load by script and weren't read (15 of 20). Public market data needs no key and the testnet is free with a GitHub login (20). A person signs up, passes Verified Plus verification, deposits and mints a key (0). 0 + 15 + 20 + 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.

## 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.

**Kraken API.** Kraken pairs a documented REST, WebSocket and FIX API with the open-source kraken-cli, whose kraken-mcp server gates 33 dangerous tools behind approval and signs in by OAuth with a no-withdrawal key. Spot has no self-service sandbox, no OpenAPI file was found, and a 59-minute connectivity outage hit every interface on 30 October 2026.

## 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

### Kraken API

1. Start kraken-mcp with -s market,paper,feedback or the default services; add trade only with a least-privilege key, and never pass --allow-dangerous on an agent that reads untrusted input
2. Ask the person to run kraken auth login in their own terminal; it needs a browser and saves a no-withdrawal key that expires in 90 days at most
3. Send a fresh --cl-ord-id on each order and run it with --validate first; after a network error look the order up before sending it again
4. Keep the nonce strictly increasing per key and stay under the tier's counter, since EAPI:Rate limit exceeded has no Retry-After header
5. Test strategies in a paper workspace, which fills at live prices with no account, before a live workspace
