Measured tools (5)

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.
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
verify_payment
Verifies a signed x402 payment payload against the supplied payment requirements. It checks validity but moves no funds.
Parameters:
- paymentPayload (required) — object
- paymentRequirements (required) — object
- x402Version — integer
- serverExtensions — object
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
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.
Parameters:
- paymentPayload (required) — object
- paymentRequirements (required) — object
- x402Version — integer
- serverExtensions — object
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
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.
Parameters:
- limit — integer
- offset — integer
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
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.
Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
