Funktionen

Tools

5 Tools
get_discovery_stats
Get Bazaar discovery statistics
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.
Eingabeschema 
{'type': 'object', 'required': [], 'properties': {}, 'additionalProperties': False}
get_supported
Get supported payment kinds
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.
Eingabeschema 
{'type': 'object', 'required': [], 'properties': {}, 'additionalProperties': False}
list_discovery_resources
List Bazaar 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.
Eingabeschema 
{'type': 'object', 'required': [], 'properties': {'limit': {'type': 'integer', 'maximum': 1000, 'minimum': 1}, 'offset': {'type': 'integer', 'minimum': 0}}, 'additionalProperties': False}
settle_payment
Settle a signed x402 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.
Eingabeschema 
{'type': 'object', 'required': ['paymentPayload', 'paymentRequirements'], 'properties': {'x402Version': {'enum': [1, 2], 'type': 'integer'}, 'paymentPayload': {'type': 'object'}, 'serverExtensions': {'type': 'object'}, 'paymentRequirements': {'type': 'object'}}, 'additionalProperties': False}
verify_payment
Verify a signed x402 payment
Verifies a signed x402 payment payload against the supplied payment requirements. It checks validity but moves no funds.
Eingabeschema 
{'type': 'object', 'required': ['paymentPayload', 'paymentRequirements'], 'properties': {'x402Version': {'enum': [1, 2], 'type': 'integer'}, 'paymentPayload': {'type': 'object'}, 'serverExtensions': {'type': 'object'}, 'paymentRequirements': {'type': 'object'}}, 'additionalProperties': False}
