agentbuilt
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

· protocol Audit AI readiness of a website audit_ai_readiness
Fetches a URL and reports how legible it is to AI assistants and agents: whether GPTBot, ClaudeBot, PerplexityBot and Google-Extended are allowed in robots.txt, how much real text survives without JavaScript, which JSON-LD entity types are declared, and whether llms.txt, sitemap.xml and an agent card exist. Returns a score, every check, and the fixes. Free.

Returns the agentbuilt catalog of pay-per-result data tools for AI pipelines, with what each does, when to use it, what it explicitly cannot do, and what it costs. Callers run them on their own Apify account.

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
