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/36`. It is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/kyc/verifications/36`) returns a live 402 challenge requesting up to $0.02 per call (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). The platform advertises a flat $0.02/request pricing across all its APIs with no API keys, no rate limits, and instant access. Payment is made via the x402 `exact` scheme to a specified wallet address.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what input the KYC verification endpoint expects or what it returns. The `outputSchema` in the 402 challenge only indicates it accepts HTTP POST requests. Without further documentation, it is unclear what request body format is required or what verification data is returned.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request format, response schema, or what the KYC verification actually does. Docs pages are empty beyond a wallet-connect prompt. No OpenAPI spec or examples exist. This is effectively a stub listing.
