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/15`. 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/15`) accepts POST requests and charges up to $0.02 per call (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach an X-PAYMENT header. The platform advertises instant access with no minimums or commitments.
Documentation is extremely sparse. The docs, API, pricing, 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 input the KYC verification endpoint expects or what it returns. The endpoint path includes an ID (`15`), but it is unclear whether this refers to a specific verification record, a verification type, or something else. The `outputSchema` in the x402 challenge only confirms it is an HTTP POST endpoint marked as discoverable.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/call in USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the KYC verification endpoint actually does or expects. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; it is unknown what input the endpoint expects or what it returns.
- —The endpoint path includes an ID (/15) whose meaning is undocumented.
- —KYC/identity verification is a regulated category — no compliance certifications or data handling policies are documented.
- —The platform lists many API categories but none specifically mention KYC on the landing page; this endpoint may be unlisted or experimental.
