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/46`. It is part of a broader platform offering 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/46`) 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. Payment is made via the x402 `exact` scheme to a specified wallet address.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema documentation, and no examples available. The endpoint path suggests it may relate to retrieving or initiating a KYC verification (resource ID 46), but the exact input parameters and response format are unknown. The POST method is indicated in the outputSchema.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation on request parameters, response schema, or what 'verifications/46' actually does. No OpenAPI spec, no examples, and all doc pages are empty. This is effectively a stub listing.
