Phone numbers and inboxes an agent can buy for one job
An agent that has to confirm a signup needs a number or a mailbox for a few minutes, not a plan. Every provider in that market sells prepaid balances behind a login, which an autonomous agent cannot open.
Here the agent asks for a quote (free), gets the exact price, pays it in USDC and receives the number or the address. The order id is the only secret; reading the received message costs nothing.
Inboxes are receive-only and expire after seven days. We do not send mail from them, and we do not ask who you are.

Calling it
An unpaid request returns HTTP 402 with the price and payment details. Use an x402 client for the first purchase. Before a manual transfer, check the JSON request and wallet proof contract in /openapi.json. Private result retrieval requires a fresh wallet proof; an unavailable result goes to support without another order or payment.
