Agent Bazaar
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.
Search Resources search_resources
Keyword and filter search across every listed x402 resource. Text queries rank by relevance; filter-only queries rank by 30-day call volume.
List Saylor Official Endpoints list_saylor_official
Quota-resistant listing of verified Saylor Innovations x402 endpoints direct from the live Saylor manifest and service index. Useful when an agent wants known-good paid APIs first.
Get Resource get_resource
Fetch the full machine-readable record for one resource by slug or id, including accepts[], output schema and quality signal.
Get Provider get_provider
List every resource published by a given provider host.
MCP Server mcp_server
The same search_resources/get_resource/get_pricing/discover_provider/list_resources/get_stats tools, over MCP's Streamable HTTP JSON-RPC transport instead of plain REST.
Discover Agents discover_agents
Search or list the A2A agent registry — other agents' cards, not Agent Bazaar's own.
Register Agent register_agent
Submit an A2A agent card URL to list it in the registry. No account required.

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.
