_done

_done is an agent-native catalog of 27 single-purpose utility REST APIs — network and DNS lookups, domain intelligence, email-authentication checks, HTTP and SEO inspection, OCR, screenshots, hashing, JSON tooling, web3 resolution and finance calculators. There are no accounts, no signups and no API keys: every call is metered individually at $0.01 in USDC over the x402 protocol, settled on Base Mainnet or Solana Mainnet through the Coinbase CDP facilitator. Each service runs on its own subdomain, exposes a single POST operation, and publishes its own OpenAPI 3.1.0 spec annotated for AI agents with x-ai-instructions, x-guidance, x-pricing and x-402 payment metadata. Discovery is served from /.well-known/x402.json, /llms.txt, robots.txt and sitemap.xml. There is no MCP server, no A2A agent card, no SDK, no changelog, no status page and no published terms of service.

_done publishes 27 APIs on the APIs.io network, including asn lookup API, cors headers API, Data API, and 24 more. Tagged areas include Developer Tools, Utility APIs, AI Agents, agent-native, and x402.

_done’s developer surface includes documentation, API reference, support, authentication, code examples, pricing, and 44 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/done: open an issue to ask a question, or submit a pull request to add artifacts.
