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/63`. It uses the x402 payment protocol, accepting USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the endpoint.
The broader lowpaymentfee.com platform advertises a range of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto data feeds, and infrastructure utilities, all priced uniformly at $0.02 per request. However, this specific listing covers the KYC verifications endpoint. The endpoint accepts POST requests and returns JSON.
Documentation is extremely sparse — the docs, API, pricing, 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 endpoint expects or what its response looks like. The endpoint is confirmed live (returns a proper 402 x402 challenge), but without documentation it is unclear what request body fields are required or what verification data is returned.

Quality
The endpoint is live and returns a valid x402 challenge, confirming it exists and accepts USDC on Base at $0.02/call. However, 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.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; request body and response format are unknown.
- —The specific purpose of '/api/v1/kyc/verifications/63' (the '63' path segment) is unexplained — it may refer to a specific verification record rather than a general endpoint.
- —KYC/identity verification is a regulated category; no compliance certifications or data handling policies are documented.
