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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/61` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header challenge — no API keys, accounts, or rate limits are required.
The parent site lowpaymentfee.com hosts a broader catalog 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, the KYC verifications endpoint is not listed on the site's public catalog, and no documentation was found describing its input schema, required fields, or response format. The docs, pricing, and API pages behind the site all render only a "Connect wallet" prompt with no additional content.
Because there is no OpenAPI spec, no request/response examples, and no documentation beyond the x402 challenge itself, the actual capabilities of this KYC endpoint remain unclear. It is live (returns a proper 402 challenge), but consumers should expect to experiment or contact the provider to learn the expected POST body and response structure.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and the KYC endpoint isn't even listed on the provider's own catalog page. Effectively a stub listing.
