stablephone.dev is a narrow-purpose lookup service targeting agents or applications that need to verify iMessage or FaceTime registration status for US phone numbers. It serves use cases such as pre-screening contacts before routing messages through Apple's ecosystem. The service is limited to NANP (+1) numbers and operates asynchronously, meaning callers must implement a polling loop to retrieve results after submitting a number.

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
Make my x402 API at https://stablephone.dev discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://stablephone.dev --json`. Heads up: 3 routes have never been scored — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
