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/84`. 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 responses.
The broader lowpaymentfee.com platform offers a suite of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto data (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints share the same $0.02-per-request pricing model with no API keys, no rate limits, and no minimum commitments — payment is handled entirely through the x402 protocol using USDC on Base.
Documentation on the site is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what the KYC verification endpoint actually accepts or returns. The specific resource ID "84" in the path is unexplained. Prospective users should expect to experiment or contact the provider for integration guidance.

Quality
The endpoint is live (returns a valid 402 x402 challenge), but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what the KYC verification endpoint accepts or returns. The resource ID '84' in the path is unexplained. Effectively a stub listing.
