You POST a phone number in E.164 format, pay $0.05 in USDC (settled on Base via x402 or Tempo via MPP), and receive a JWT token. The lookup is asynchronous (typically 30–90 seconds). You poll `GET /api/lookup/status?token=<jwt>` (authenticated via SIWX) until the result resolves to `complete`, at which point you get iMessage availability (`available`, `unavailable`, or `unknown`), FaceTime availability, carrier information (carrier name and number type), and country metadata. Results for the same number are cached for approximately one hour, so repeated lookups within that window don't incur additional charges. Tokens expire after 60 minutes.\n\nThis endpoint is part of the broader StablePhone API, which also offers AI-powered phone calls ($0.54/call), dedicated phone number provisioning ($20.00 for 30 days), and number top-ups ($15.00 per 30-day extension). All paid endpoints use x402 or MPP payment protocols — no API keys or accounts required. Free status-polling endpoints use SIWX (Sign-In With X) wallet authentication, restricting access to the wallet that initiated the request.\n\nThe endpoint accepts only POST requests. The probe returned 405 on HEAD and GET, which is expected since the OpenAPI spec defines it as POST-only. The endpoint is live and correctly configured.","tags":["phone","call","voice","ai-call","imessage"],"capabilities":["imessage-lookup","facetime-lookup","carrier-detection","phone-number-validation","async-polling","usdc-payment","x402-protocol","mpp-tempo-settlement","siwx-auth","e164-format"],"categories":["telecom","lookup"],"synonyms":["iMessage check","FaceTime check","phone number lookup","Apple messaging detection","iMessage availability","carrier lookup","phone type detection","blue bubble check"],"warnings":["Probe returned 405 because HEAD/GET were used on a POST-only endpoint; this does not indicate the endpoint is down","The /docs page returns 404 — all documentation comes from the OpenAPI spec and llms.txt guidance","Phone number pattern restricts to +1 (US/CA) numbers only","Lookup is async (30-90 seconds); token expires after 60 minutes"],"endpointUrl":"https://stablephone.dev/api/lookup","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stablephone.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.820","qualityRationale":"Full OpenAPI schema with request/response definitions, detailed guidance docs, clear pricing ($0.05), and well-documented async polling flow.
