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/16`. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and infrastructure utilities. The endpoint uses the x402 payment protocol, settling on the Base network in USDC.
The x402 challenge confirms the endpoint is live and accepts POST requests. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The platform advertises a uniform $0.02/request pricing model across all its endpoints, with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the KYC verification endpoint actually accepts or returns. The specific resource path (`/verifications/16`) suggests this may be a fixed resource ID rather than a parameterized endpoint, but this is unclear without documentation. The endpoint's actual KYC functionality, required input fields, and response format are unknown from the available material.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the KYC verification endpoint actually does or requires. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all return only a wallet-connect prompt with no content.
- —No OpenAPI or input/output schema provided; request body and response format are completely unknown.
- —The path `/api/v1/kyc/verifications/16` contains a hardcoded ID; it is unclear if this is parameterized or fixed.
- —KYC/identity verification is a regulated category — no information on data handling, compliance certifications, or privacy policies is available.
- —The platform lists many API categories but the KYC endpoint is not listed on the homepage, raising questions about its status.
