Hosted Cloudflare Worker exposing Polymer Labs' Prove API v2 for the Base network — submit proof generation jobs and poll their status. The single endpoint (/x402/v1) accepts proof_request (returns a job ID) and proof_query to check results; it also supports payment proofs for dispute resolution and on-chain settlement workflows. Priced per call at $0.01, this endpoint is suitable for integrating verifiable proof workflows into dApps, tooling, and analytics pipelines (docs: https://docs.polymerlabs.org/docs/build/prove-api-V2/api-endpoints).
