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/21` accepts POST requests and charges up to $0.02 per call 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 hosting site lowpaymentfee.com offers 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 verification endpoint's input schema, required POST body fields, and response format are not documented in any crawled page. The docs, pricing, and API pages all resolve to a minimal "Connect wallet" prompt with no further detail. Because of this, the exact capabilities and data returned by the KYC verification call remain unclear.

Payment settles on Base using USDC (contract 0x8335…2913) to address 0x1A2B…85F3, with a maximum timeout of 300 seconds. The endpoint is live and returns a valid x402 challenge (HTTP 402).

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, required fields, or what the KYC verification actually checks. Docs pages are empty stubs. The listing is effectively a stub with only pricing and protocol details confirmed.

Warnings

  • —No documentation available for request body schema or response format
  • —All doc/pricing/API pages resolve to a minimal 'Connect wallet' prompt with no content
  • —The exact nature and scope of the KYC verification is unknown — 'verifications/21' may refer to a specific verification record rather than a general-purpose endpoint
  • —No OpenAPI spec or AI plugin manifest found
  • —Regulated category (KYC/identity) — verify vendor compliance certifications independently
