What it does

This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/47`. It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with payment proof before granting access. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request.

The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific listing is for the KYC verifications endpoint. The exact input schema and response format are not documented in the crawled material; the endpoint accepts HTTP POST requests and returns application/json.

Note that the endpoint path includes a numeric ID (`47`), which may represent a specific verification record or configuration. Without further documentation it is unclear whether this ID is user-supplied or fixed. The docs, pricing, and README pages on the site all render only a "Connect wallet" prompt with no additional technical documentation.

Quality

The endpoint is live and returns a valid x402 402 challenge, confirming it accepts USDC on Base at $0.02/call. However, there is no documentation of request/response schemas, no explanation of what the KYC verification actually checks or returns, and the docs pages are empty. The endpoint path contains a hardcoded ID with no explanation. This is effectively a stub listing.

Warnings

  • No API documentation available — docs, pricing, and README pages all render only 'Connect wallet'
  • Request body schema and response schema are completely undocumented
  • The endpoint path includes a fixed ID (47) with no explanation of its meaning
  • KYC/identity verification is a regulated category — verify compliance requirements before use
  • Cannot confirm what data the KYC verification actually checks or returns
