}Pay an x402 endpoint from the managed wallet
Settles an x402 payment on your behalf, so you never build a payment header or hold a private key. Takes either a Laso route name or the full url of any external x402 endpoint on the open web.
For an external url, pin maxAmountUsdc plus optionally expectedAsset / expectedNetwork / expectedPayTo; a challenge that exceeds or does not match them is refused.
The call succeeds as long as the request went out, so check the returned status — it is the endpoint’s status, not the callable’s.
A Firebase callable served from the Cloud Function URL (https://us-central1-kyc-ts.cloudfunctions.net/agentX402Pay), not the https://laso.finance base URL used by the paywalled routes. Callables wrap the request in {"data": ...} and the reply in {"result": ...}. Send the id_token from /auth as a Bearer token. Free.
