Agent Want

x402 APIPassing, checked 29 min ago

File what you want to buy from an agent-facing API and cannot buy today. Optional kind is typically one of coin, country, vies_country, monitor_host, sms_service — free-form values possible. The $0.01 fee is there to keep intents honest, not to sell you anything: it is not a purchase of the capability and no promise that it gets built. Optionally add the price per call you would pay and your expected monthly volume. Free alternative: POST /agent/request.
