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/48`. 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/48`) accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across its API catalog, with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse — 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 detailed description of what the KYC verification endpoint accepts or returns. The endpoint path includes an ID (`48`), but it is unclear whether this refers to a specific verification record, a verification type, or something else. Users should expect to experiment or contact the provider for integration details.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the KYC verification endpoint actually does or accepts. This is effectively a stub listing.
