What it does

This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/23`. It uses the x402 payment protocol, accepting USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). The endpoint requires a POST request and returns JSON.

The broader lowpaymentfee.com platform offers a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML (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 using USDC on Base.

Note that the specific KYC verification endpoint (`/api/v1/kyc/verifications/23`) is not listed on the site's public API catalog, and no documentation was found describing its input schema, required fields, or response format. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content. As a result, the exact functionality, required request body, and response structure of this particular endpoint remain unclear.

The endpoint is live (returns a valid x402 402 challenge), but there is no documentation for the KYC verification endpoint specifically — no input schema, no response examples, and the endpoint path includes a hardcoded ID (23) with no explanation. The docs pages are empty beyond a wallet connect prompt.

Warnings

  • —No documentation found for the /api/v1/kyc/verifications/23 endpoint — input schema and response format are unknown.

  • —The path includes a hardcoded resource ID (23); it is unclear whether this is parameterized or fixed.
  • —KYC/identity verification is a regulated category — verify the provider's compliance posture before relying on this for production use.
  • —Docs, pricing, API, and README pages all returned only 'Connect wallet' with no substantive content.
