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/95`. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and infrastructure utilities. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint listed here accepts POST requests and costs $0.02 per call (20,000 base units of USDC with 6 decimals). Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second payment timeout.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned 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 (`95`), but it is unclear whether this is a fixed resource or a variable parameter. The platform's landing page confirms uniform $0.02 pricing and lists categories of APIs but does not specifically list KYC endpoints, making this endpoint's exact functionality uncertain.

Quality
The x402 challenge is live and confirms pricing and network, but there is zero documentation on request format, response schema, or what the KYC verification actually does. No OpenAPI spec, no examples, and the docs pages are empty. 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 request/response schema provided; input and output formats are unknown.
- —The endpoint path includes a fixed ID (95) whose meaning is unclear — it may be a specific resource rather than a general verification endpoint.
- —KYC/identity verification is a regulated category; no information on data handling, compliance certifications, or privacy policy is available.
- —The platform landing page does not list any KYC endpoints among its advertised APIs, raising questions about this endpoint's status.
