Binance API vs dYdX

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.

dYdX 83

Read with the hosted lines on the indexer API and the chain endpoints the clients submit to. status.dydx.trade is an Atlassian Statuspage with Frontends, dYdX Chain, Indexer, Order Gateway and Client Libraries components and an RSS history (20). From 1 August to 3 November 2026 the feed has eight items, seven scheduled maintenance windows of 29 minutes to 2 hours (indexer on 9 September, 8 and 15 October, protocol v9.7 on 11 September and v9.8.0 on 12 October, WebSocket compression on 26 and 28 October) and one degraded instant-deposit path through an onboarding partner from 24 to 29 September, outside the trading API. Clean or trivial (30). Rate limits documented with numbers for the indexer, the block limits and the public nodes (15). No 429 shape or Retry-After for the indexer; short-term orders expire by goodTilBlock and client IDs let an agent find an order after a timeout (8 of 15). No SLA (0). Mainnet generally available; the Order Entry Gateway is marked testnet-only (10). 20 + 30 + 15 + 8 + 0 + 10 = 83.

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.

dYdX 58

No OpenAPI file found for the indexer; the docs publish a types reference of about 200 pages (OrderSide, TimeInForce, OrderStatus and the rest) and the chain's protobuf messages are in the clients (8 of 25). llms.txt and Markdown docs (10). Endpoint pages describe each call and the guides say when to use short-term against long-term orders and the indexer against the node, but descriptions are short (12 of 20). Enums and types on every field in the reference, with pagination and cursor parameters typed (11 of 15). Examples in Python, TypeScript and Rust for each step; errors are described by HTTP status (400 malformed, 404 not found) with no code list (9 of 15). A /v4 path, protocol releases dated on the status page, deprecated rate-limit fields marked, but no API changelog (8 of 15). Total 58.

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.

dYdX 60

No machine payment protocol (0). Fees public per tier without login (20). Testnet with a faucet and no card anywhere (20). No signup; an agent with a funded wallet trades, subject to the geographic terms (20). Total 60.

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.

dYdX 66

An API, read for response sizing. limit on list endpoints, candles by resolution, sparklines by period; the order book comes whole (16 of 25). limit, page on fills, transfers and funding, and height or time cursors (16 of 20). Indexer errors are a status and a sentence; order rejections come back from the chain as transaction results the clients surface (8 of 20). Unique 32-bit client IDs, goodTilBlock expiry on short-term orders, cancel by order ID; no MCP annotations apply (14 of 20). Few required fields with market parameters fetched for unit conversion, and official clients in TypeScript, Python and Rust (12 of 15). Total 66.

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.

dYdX 50

The editorial half. Clients AGPL-3.0 with a terms-bound use condition, the chain under a custom licence, two terms documents (dYdX Trading Inc.'s v4 terms of 12 March 2026 and dYdX International Ltd's of 6 June 2025) that are clear about who runs nothing (22 of 30). The privacy policy of 6 June 2025 names dYdX International Ltd, keeps technical data until no longer necessary with no periods, and names no subprocessors; nothing covers the unnamed indexer operator (12 of 30). Protocol upgrades and the WebSocket compression change were posted as dated maintenance notices, deprecated rate-limit fields are marked, but no deprecation policy or notice period is stated (10 of 20). The policy says data may be processed in the EEA and elsewhere, with no subprocessor list (6 of 20). Total 50.

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.

dYdX 78

Orders are signed by the account key or by a permissioned key the owner adds as an authenticator, limited by message type, subaccount and market with AllOf or AnyOf, and revoked by remove_authenticator; no shared secret and nothing in a URL (28 of 30). A key can be confined to placing and cancelling orders on one subaccount with withdrawals and transfers excluded, though not to a position or order size, and the interface's default API wallet trades all cross-margin pairs (16 of 20). The API returns no untrusted content (10). Every action is a chain transaction and the indexer lists fills, orders and transfers per subaccount, and authenticators can be listed; no per-key log (10 of 15). A Cantina bug bounty up to $1,000,000 sponsored by dYdX Trading Inc. over the protocol, indexer, web client and SDKs, an Informal Systems audit; no security.txt and no certification (14 of 20). Total 78.
