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 expec

PhoneAgent — countries with rentable SMS phone numbers for AI agents. Returns 190+ supported countries, each with the number of services offered and the cheapest price tier ($1, $2, or $5 USDC). Add ?service=<alias> (e.g. tg, wa, go, zo for OpenAI, other for any platform) to see which countries carry that service with live price and inventory pool. Companion route GET /services lists all 1,000+ se

Generate scannable QR codes from any text, URL, or structured payload (WiFi, vCard, SMS, email, geo, crypto). Returns PNG by default with JPG, WebP, and SVG output, plus optional error-correction, sizing, color, version, and encoding controls. Simple cURL POST: send qr_data, receive an image.

Send one SMS to a mobile number, paid per message in USDC with x402. Use it when an agent must notify a person by text. The 402 quotes the exact price for the destination and message length. No account and no API key: any wallet that pays sends in one call. An opt-out link is appended to the message, and numbers that opted out are refused. Returns an order; poll GET /v1/orders/{id} for delivery st

Creates a five-minute inbound SMS lease through a configured licensed provider, polls received messages, and releases the number upstream on cancellation, expiry or failed x402 settlement. Twilio is supported directly; an HTTPS bearer-token lease provider can also implement the documented generic contract. Messages and lease metadata are removed after expiry.

Buy one virtual number for SMS verification. First GET /agent/v1/quote, then POST here with X-Quote-Id and Idempotency-Key (service_id/country_id in the query string). The 402 advertises the locked price. If no number is available the API answers 409 no_numbers and nothing is charged.
