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/34`. It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with payment proof before granting access. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD per request.
The broader lowpaymentfee.com platform advertises a range of API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced uniformly at $0.02 per request. The platform emphasizes a no-API-key, no-rate-limit, pay-per-use model settled on the Base network. However, the specific KYC verification endpoint (`/api/v1/kyc/verifications/34`) is not listed on the site's public landing page, and no documentation, input schema, or example responses are available for it. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content.
Because there is no published documentation describing what this KYC endpoint accepts as input or returns as output, its actual functionality is unclear. The path suggests it may relate to retrieving or submitting a verification record (ID 34), but this is speculative. The endpoint is confirmed live (402 challenge captured), and the payment parameters are well-defined.

Quality
The endpoint is live and returns a valid x402 challenge with clear payment parameters. However, there is no documentation, no input/output schema, no example requests or responses, and the specific KYC endpoint is not even listed on the provider's landing page. Functionality is essentially unknown beyond the path name.
