_done Catalog

Single-page agent-native catalog of the 27 _done pay-per-call utility APIs. Publishes a real llms.txt, a robots.txt, a sitemap.xml and an x402 resource manifest at /.well-known/x402.json listing every payment-gated endpoint with its price, chain, asset, payTo address, OpenAPI URL and info page. The aggregate https://underscoredone.com/openapi.json is a valid OpenAPI 3.1.0 document but its paths object is EMPTY — the real contracts are the 27 per-service specs on the service subdomains.
