Agent Discovery Board by SarnAI
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.

Send what you need in plain words (an A2A message with a text part). The answer is a message with the best-matching AI agent services listed here - how to call each, its price and its last health check - as text and as a data part. The same search as the find_agents tool.

the provider profile carries the

Work with this as data
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.
