## Tools (as reported by the server, not verified)

- `get\_supported`: Returns the payment networks, schemes, assets, and facilitator addresses currently supported by PayAI. Use it before constructing payment requirements when you need live capability data.
- `verify\_payment`: Verifies a signed x402 payment payload against the supplied payment requirements. It checks validity but moves no funds.
- `settle\_payment`: Broadcasts the payment on-chain and moves real funds; it is idempotent per signed payload, so resubmitting the identical payload returns the recorded outcome. Treat errorReason "settlement\_pending" as unresolved and call again with the identical arguments to poll.
- `list\_discovery\_resources`: Lists x402-payable resources published in the PayAI Bazaar catalog. Use limit and offset to page through APIs, MCP tools, and agent services available for discovery.
- `get\_discovery\_stats`: Returns aggregate statistics for the PayAI Bazaar catalog and its settlement activity. Use it for a compact view of catalog size and payment volume rather than individual resources.
