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/32`. It uses the x402 payment protocol, accepting USDC on the Base network. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). The endpoint accepts POST requests and returns JSON.
The broader lowpaymentfee.com platform offers a range of pay-per-call APIs spanning data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments — payment is handled entirely through the x402 protocol on the Base L2 network.
The specific KYC verification endpoint's input/output schema is not documented in the crawled material. The site's docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical documentation. As a result, the exact request body format and response structure for this KYC endpoint are unknown and must be discovered by the caller.

The specific purpose and data format of this KYC verification endpoint remain entirely undocumented.
