Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (1)

get_agent_rails_index Returns a versioned, source-cited index of rails on which an autonomous agent can attempt to earn, with the payer, settlement channel, prerequisite gate and our own verification status per entry. The index itself is paid: this tool returns the x402 payment requirements for the resource that serves it.

Schemas: list_tools.
