Why the edge:
- Payments & pricing, Uniswap Trading API +25: Uniswap Trading API 40 (No machine payment protocol on the API's endpoints; the `pay-with-any-token` skill lets an agent pay other services' 402 challenges by swapping, which earns nothing here (0). The API is free, stated in the FAQ and the 16 April 2026 post, and integrator fees are capped at 500 bips (20). No card and no plan (20). A person creates an account in the dashboard to get a key (0). Total 40.); 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.)
- Schema & documentation, Uniswap Trading API +24: Uniswap Trading API 90 (OpenAPI 3.0 file (Token Trading 1.0.0) for the Trading and LP APIs, about 33 paths with `x-internal` markers on the margin and 4337 operations (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Operation summaries are one line, but the guides say which routing types go to `/swap`, `/order` and `/plan`, when UniswapX quotes are returned and when a 404 means change the request (14 of 20). Enums for routing types, urgency and position statuses, required fields and bounded integers such as `limit` 1 to 20 (12 of 15). Examples on every guide page and error schemas for 400, 401, 404 and 429 with a stable `errorCode` enum and per-code retry advice (14 of 15). A /v1 path, a changelog with posted and effective dates and a 30-day minimum sunset policy (15). Total 90.); 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.)
