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/26`. It uses the x402 payment protocol on the Base network, accepting USDC (USD Coin) for per-request payment. The x402 challenge is live and returns a 402 with a payment requirement of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access via the x402 protocol on the Base L2 network. However, the specific KYC verification endpoint's input schema and response format are not documented in the crawled material. The endpoint accepts HTTP POST requests and returns `application/json`.
Because the docs pages, pricing page, and README all returned only a "Connect wallet" prompt with no substantive content, there is very limited documentation available about what data this endpoint expects as input or returns as output. The endpoint path suggests it may be scoped to a specific verification record (ID 26), but it is unclear whether this is a template parameter or a fixed resource. Users should expect to experiment or contact the provider for integration details.

Quality
The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation for the KYC endpoint's input/output schema, no OpenAPI spec, and all doc pages returned only a wallet-connect prompt. The endpoint path includes a hardcoded ID (26) with no explanation. This is effectively a stub listing.
Warnings
