Why the edge:
- Maintenance & community, Upbit Open API +26: Coinbase Advanced Trade API 57 (Read as a closed hosted service. The last change to the API itself is the Global Derivatives gateway and INTX retirement of 1 October 2026, 33 days before this check; the Python SDK's v2.0.0rc1 is from 30 September (20 of 30). Dated changes in 90 days are the 1 October migration and the agents entries of 17 and 21 August, which run through Advanced Trade (12 of 20). A public changelog and a CDP Discord; SDK issues not read (8 of 15). Official Python SDK current, the rest samples (12 of 15). SDK CI not read (5 of 10). 20 + 12 + 8 + 12 + 5 = 57.); Upbit Open API 83 (Read as a closed service. SDK v1.1.0 on 20 October 2026 (30). The CLI 1.0.0 on 1 September, the rate-limit update of 7 October, the SDK on 20 October and the path-format notice for 16 November 2026 (20). open-api@upbit.com answers in turn on weekdays per the support notice, notices carry dates, and the six upbit-official repositories show no open issues (12 of 15). Current official SDKs in Python, TypeScript and Go (15). Apache-2.0 repositories pushed in October 2026; CI not checked (6 of 10). 30 + 20 + 12 + 15 + 6 = 83.)
- Reliability, Coinbase Advanced Trade API +16: Coinbase Advanced Trade API 58 (Read with the hosted lines. status.coinbase.com is a Statuspage site with Coinbase Advanced Trade, API, US Derivatives and International Derivatives components (20). The incidents feed we could read runs from 16 September to 3 November 2026. In it Advanced Trade was degraded for 25 minutes on 21 September, the website had a 3-minute major on 14 October, converts were down 1 hour 4 minutes on 26 October, and no incident named the API; 5 August to 15 September was beyond the feed, so minor only for the seven weeks read (15 of 30). No REST rate limit with numbers was found; the older rate-limits page answers 404 and llms.txt lists none, while the WebSocket page gives 8 connections and 8 unauthenticated messages per second per IP (5 of 15). Orders take a client_order_id, but no 429 or Retry-After guidance was found for Advanced Trade (8 of 15). No SLA (0). REST and WebSocket are generally available; the Global Derivatives gateway is a month old and not marked beta (10). 20 + 15 + 5 + 8 + 0 + 10 = 58.); Upbit Open API 42 (Read with the hosted lines. No status page found on docs.upbit.com or in llms.txt; a wallet-status endpoint and an announcements stream stand in (0). No readable incident history (5). Rate limits documented with numbers per group, per IP and per pocket, updated 7 October 2026 (15). 429 then 418 with a stated block length and a Remaining-Req header, an order-test endpoint and a self-match-prevention default; an order identifier for safe retries was not checked (12 of 15). No SLA found (0). Generally available (10). 0 + 5 + 15 + 12 + 0 + 10 = 42.)
- Schema & documentation, Coinbase Advanced Trade API +14: Coinbase Advanced Trade API 80 (Public OpenAPI 3.1 spec (45 paths, 51 operations) and an AsyncAPI document (25). llms.txt and a Markdown twin of every docs page (10). Every operation has a summary and description, some one line, several with multi-sentence guidance for equities (14 of 20). Enums on product_type, granularity, order_status, time_in_forces, order_types, order_side and sort_by, with defaults (13 of 15). Examples in the docs and the sandbox's simulated errors, but the spec documents only a default error referencing grpc.gateway.runtime.Error, with no 4xx or 429 shapes (8 of 15). Paths carry /api/v3, the CDP changelog is dated, and the INTX retirement was announced with a date, but the spec's info.version is 0.1 and the October gateway change has no changelog entry (10 of 15). 25 + 10 + 14 + 13 + 8 + 10 = 80.); Upbit Open API 66 (No OpenAPI found; the reference is a readme.io site with a Markdown twin of every page (5 of 25). llms.txt on docs.upbit.com and a kr/llms.txt index (10). Each reference page states what the endpoint does, its group and its errors, with warnings such as market_offline after maintenance (14 of 20). Typed parameters with enums for order type, side and time in force and required flags (11 of 15). Recipes in Python, Java and Node.js and an error format of error.name and error.message with HTTP statuses (13 of 15). Feature versions in page histories (v1.6.1) and dated notices with effective dates, no single API version (13 of 15). 5 + 10 + 14 + 11 + 13 + 13 = 66.)
- Transparency & trust, Coinbase Advanced Trade API +13: Coinbase Advanced Trade API 67 (The editorial half. A closed service whose user agreement answered a bot check; the OpenAPI spec is public and the Python SDK is open on GitHub (12 of 30). Privacy facts per the coinbase-cdp-agentkit check of 1 October 2026 (Coinbase, Inc., processing countries, retention tied to need without numbers), not re-read (10 of 30). INTX endpoints retired on 1 October 2026 with a dated notice and a read-only grace period (12 of 20). Processing countries and provider categories per the same earlier check, no subprocessor list (8 of 20). 12 + 10 + 12 + 8 = 42.); Upbit Open API 54 (The editorial half. A closed service whose user and Open API terms could not be fetched under upbit.com's robots.txt, and whose SDK licence page calls the SDK material not open source while the repositories carry Apache-2.0 (8 of 30). The developer centre's privacy policy names Dunamu Inc., gives retention periods and names Zendesk in Japan; the main privacy policy was not read (14 of 30). Notices with effective dates, including the path-format change and the deprecated Remaining-Req min field (12 of 20). Zendesk and Google Analytics named with a location for the developer centre only (8 of 20). 8 + 14 + 12 + 8 = 42.)
- Security & auth, Coinbase Advanced Trade API +9: Coinbase Advanced Trade API 68 (CDP keys with view, trade and transfer permissions, a portfolio restriction, an optional IP allowlist, revocation in the portal, ES256 JWTs that expire after 2 minutes, and OAuth2 with wallet:* scopes for other people's accounts; no key expiry (28 of 30). View-only keys and portfolio scoping limit an agent, and transfer is a separate permission, but no withdrawal address allow-list for API keys and no confirmation step were found (14 of 20). The API returns no untrusted content (10). key_permissions reports a key's scope and account activity shows in the app, but no per-call log was found (6 of 15). HackerOne bug bounty named in a security.txt that expired on 1 June 2024; certifications unread behind a bot check (10 of 20). 28 + 14 + 10 + 6 + 10 = 68.); Upbit Open API 59 (Keys limited to chosen functions, a mandatory public IPv4 allow-list, a JWT per request with a fresh nonce, keys listed with expiry through the API, and a withdrawal safe-lock on by default (27 of 30). Read-only keys, the default withdrawal lock lifted only in the app, and skills that require a typed CONFIRM before writes (17 of 20). The API returns exchange data and announcements, no third-party content (10 of 15). An API key list endpoint; no per-call log for the operator (5 of 15). No disclosure policy, bug bounty or certification found; security.txt on upbit.com could not be fetched under its robots.txt (0 of 20). 27 + 17 + 10 + 5 + 0 = 59.)
- Payments & pricing, Coinbase Advanced Trade API +5: Coinbase Advanced Trade API 20 (No machine payment protocol on the API (0). The fee schedule answered a bot check on 3 November 2026, so no per-trade price was read, and the docs give none (0 of 20, unchecked). Six public market endpoints and the sandbox need no key or card (20). A person signs up, passes verification and mints a key in the portal (0). 0 + 0 + 20 + 0 = 20.); Upbit Open API 15 (No machine payment protocol (0). The fee schedule is on upbit.com, which disallows every crawler path, so no price is recorded (0 of 20, unchecked). Public quotation endpoints need no key, card or account; trading needs a verified Korean account. Judgement call (15 of 20). A person must sign up, pass identity checks and issue keys on the PC web site (0). 0 + 0 + 15 + 0 = 15.)
