What it does

This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/17`. It uses the x402 payment protocol, accepting USDC on the Base network. The endpoint is live and returns a standard 402 challenge when called without payment.

The specific endpoint charges up to $0.02 per request (maxAmountRequired of 20,000 base units of USDC, which has 6 decimals = $0.02). Payment is made via the x402 exact scheme to the specified wallet address. The endpoint accepts POST requests and returns JSON. No API keys or rate limits are advertised — access is gated purely by micropayment.

The broader lowpaymentfee.com platform hosts a variety of pay-per-call APIs across categories including data analytics, AI/ML inference (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 listed at $0.02 per request. However, this specific listing is for the KYC verifications endpoint, which is not prominently documented on the site's landing page. No detailed documentation, request/response schemas, or examples are available for this endpoint — the docs, pricing, and API pages all render only a wallet-connect prompt with no further content.

Quality

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no documentation, no request/response schema, no examples, and the KYC verifications endpoint is not listed on the site's landing page. The docs/pricing/API pages are empty beyond a wallet-connect prompt. The actual functionality behind this endpoint is entirely opaque.

Warnings

  • —The KYC verifications endpoint is not listed among the site's advertised APIs — its purpose and expected input/output are unknown.
  • —No documentation, request schema, or response schema is available for this endpoint.
  • —All documentation pages (docs, pricing, API, README) render only a wallet-connect prompt with no useful content.
  • —KYC/identity verification is a regulated category — verify the provider's compliance credentials before relying on this service.
  • —The '/17' path suffix suggests a specific resource ID; it is unclear whether this is a fixed endpoint or a parameterized route.
