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/10` accepts POST requests and charges up to $0.02 per call, settled in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header to each request.
The host 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 specific listing is for the KYC verifications endpoint. The crawled documentation pages were essentially empty (showing only a "Connect wallet" prompt), so the exact request/response schema for this KYC endpoint is unknown. The endpoint is confirmed live — it returns a proper 402 x402 challenge when called without payment.
Because no OpenAPI spec, request body schema, or response examples are available, agents will need to experiment or obtain documentation from the provider to understand the required input fields and output format. The pricing is clear ($0.02 per call in USDC on Base), and the endpoint is discoverable via the x402 challenge.
