KYC verification endpoint on Base, paid per-call via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/74`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/kyc/verifications/74`) returns a live 402 challenge requesting payment of up to 20,000 base units of USDC (0.02 USD) per call. The platform advertises a flat $0.02/request pricing model with no API keys, no rate limits, and instant access. The endpoint accepts HTTP POST requests and returns `application/json` responses.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what input the KYC verification endpoint expects or what it returns. The resource path includes a numeric ID (`74`), but it is unclear whether this refers to a specific verification record, a verification type, or something else. Without documentation, the actual functionality and required request body remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what the KYC verification actually does. No OpenAPI spec, no examples, and all doc pages are empty. This is effectively a stub listing.
