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/65`. 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/65`) 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. The endpoint accepts POST requests and returns application/json.
Documentation is extremely thin — the docs, pricing, API, 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 fields the KYC verification endpoint expects or returns. The endpoint path includes a numeric ID (65), suggesting it may be a lookup or status check for a specific verification record rather than a creation endpoint, but this is speculative. Without documentation or example payloads, integrators will need to experiment to determine the expected request body and response format.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and all doc pages render only 'Connect wallet'. The specific purpose of the /kyc/verifications/65 path is unclear. This is effectively a stub listing.
Warnings
- —No documentation available — all doc/pricing/API pages show only 'Connect wallet'
- —No OpenAPI or request/response schema provided for this endpoint
- —The path includes a hardcoded ID (65); unclear if this is a generic endpoint or a specific record lookup
- —KYC/identity verification is a regulated category — no information on provider compliance certifications
- —The platform lists many diverse API categories but provides no evidence of actual functionality behind them
