KYC verification endpoint on Base, pay-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/14`. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/kyc/verifications/14`) accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request), consistent with the platform's uniform $0.02/request pricing. Payment is made via the x402 "exact" scheme to a specified wallet address, with a 300-second timeout. No API keys or rate limits are advertised — access is gated entirely by the x402 micropayment.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further 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 segment (`/14`), but it is unclear whether this is a resource identifier, a verification type, or something else. Prospective users should be aware that the actual functionality behind this endpoint is unverified beyond the x402 challenge metadata.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request format, response schema, or what the KYC verification actually does. No OpenAPI spec, no examples, and all doc pages are empty. 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 request or response schema provided; it is unknown what input the endpoint expects or what it returns.
- —The meaning of the path segment '/14' is unclear — it may be a resource ID, verification type, or placeholder.
- —KYC/identity verification is a regulated category; no compliance certifications or data handling policies are documented.
- —Actual endpoint functionality is unverified beyond the x402 payment challenge.
