Why the edge:
- Schema & documentation, Deribit +22: Deribit 88 (OpenAPI 3.0.0 for the whole JSON-RPC surface (Deribit API 2.1.1, about 1.4 million characters) plus AsyncAPI files for the WebSocket side (25). llms.txt with production and upcoming indexes, and a Markdown twin of every page (10). Each operation has a description such as "Places a buy order for an instrument." with parameter notes, and the articles say when to use WebSocket subscriptions over polling, but the reference seldom says when not to use a method (13 of 20). Parameters are typed with enums (order `type` has eight values, `time_in_force` four) and required flags, with `amount` or `contracts` as a documented either-or (13 of 15). Every reference page carries an example request and response, and the errors page lists about 159 codes with retry guidance, though most operations document only a 200 response and the smaller error tables disagree with the full one on two codes (12 of 15). A versioned path (/api/v2), a production and an upcoming docs branch, and a dated changelog of 64 entries since 21 January 2020 (15). Total 88.); 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.)
- Maintenance & community, Upbit Open API +18: Deribit 65 (Read as a closed service. The JSON-RPC changelog's latest production entry is 13 October 2026 and an entry dated 5 November 2026 describes the next release; Deribit's posts of 14 October and 2 November 2026 change fees (30). Entries of 18 August, 15 September and 13 October 2026, three in 90 days (20). A public changelog and a support site; whether support answers wasn't tested and the support site refused our reader (10 of 15). No official SDK and no MCP registry entry (0). The OpenAPI and AsyncAPI files are maintained with the docs (5 of 10). Total 65.); 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.)
- Payments & pricing, Deribit +10: Deribit 25 (No machine payment protocol (0). The fee schedule is on support.deribit.com, which answered 403; Deribit's own posts give VIP4 to VIP7 taker fees and the 0 bps linear options maker fee, so partial prices are public but the lowest tier is unchecked (5 of 20). Public market data needs no key and the test environment is free, with no card anywhere (20). A person signs up in a browser with identity checks before any key exists (0). Total 25.); 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.)
- Transparency & trust, Upbit Open API +8: Deribit 46 (The editorial half. A closed service whose terms (Deribit FZE membership terms and DRB Panama Inc. terms) sit on a support site that answered 403, with the entity confirmed on VARA's register (12 of 30). The privacy policy was not read, and nothing in the docs states retention (0 of 30). The changelog marks deprecations and the upcoming docs branch previews the next release, but removals such as `public/get_index` on 25 November 2025 carry no notice period (10 of 20). No subprocessor or data-location statement found (0 of 20). Total 22.); 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.)
