工具清单
工具（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.

"properties": {},
"required": [],
"additionalProperties": false
}⚪verify_payment(paymentPayload, paymentRequirements, serverExtensions, x402Version)
Verifies a signed x402 payment payload against the supplied payment requirements. It checks validity but moves no funds.
输入模式
{
"type": "object",
"properties": {
"paymentPayload": {
"type": "object"
},
"paymentRequirements": {
"type": "object"
},
"serverExtensions": {
"type": "object"
},
"x402Version": {
"type": "integer",
"enum": [
1,
2
]
}
},
"required": [
"paymentPayload",
"paymentRequirements"
],
"additionalProperties": false
}⚪settle_payment(paymentPayload, paymentRequirements, serverExtensions, x402Version)
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.
