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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/73` accepts POST requests and charges $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header — no API keys, accounts, or rate limits are required.
The provider site (lowpaymentfee.com) hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. However, the specific KYC verifications endpoint is not listed on the provider's public landing page, and no documentation, request schema, or response schema is available for it. The crawled docs, pricing, and API pages all returned only a "Connect wallet" prompt with no additional content.
Because there is no published documentation describing what input this KYC endpoint expects or what it returns, agents should treat this as an exploratory or experimental endpoint. The x402 challenge is live and well-formed, confirming the endpoint is operational, but the lack of any input/output schema or usage examples limits practical usability without trial-and-error.
