KYC verification endpoint on Base, pay-per-call via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/2` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header to each request.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, this specific endpoint focuses on KYC verification. The platform advertises no minimums, no commitments, and instant access.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the KYC verification endpoint expects or returns. The endpoint is confirmed live (returns a proper 402 x402 challenge), but without documentation it is unclear what input the POST body should contain or what the verification response looks like.

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 checks. All doc pages return only 'Connect wallet' with no content. This is effectively a stub listing.
