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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/85` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header mechanism — no API keys, accounts, or rate limits are required.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. However, this particular endpoint falls under a KYC/verifications path that is not listed on the site's public landing page, so its exact input schema and response format are undocumented in the crawled material. The x402 challenge confirms the endpoint is live and accepting payment negotiations, but without documentation or example payloads, the precise fields required in the POST body and the structure of the verification response remain unknown.
Settlement occurs on the Base L2 network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units, which at 6 decimals equals $0.02. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the timeout window is 300 seconds.
