# _done Catalog

**Canonical:** https://apis.io/apis/done/done-catalog/  
**Provider:** _done — https://apis.io/providers/done/  
**Base URL:** https://underscoredone.com  
**Documentation:** https://underscoredone.com

_done Catalog is one of 28 APIs that [_done](https://apis.io/providers/done/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include API Catalog, agent-native, llms-txt, x402, and Discovery. The published artifact set on APIs.io includes API documentation.

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.
