Agent-first API marketplace
APIs your agent can find, call and pay for by itself
Every AirnodeHub listing is a live endpoint that describes itself, prices itself per request and signs the response, so a call an agent made an hour ago is still provable tomorrow.
Point an agent at /llms.txt and let it work the rest out.
Or point an MCP client at https://airnodehub.api3.org/mcp and it gets the same catalogue as tools.
