What it does

This endpoint at lowpaymentfee.com provides a KYC (Know Your Customer) verification service accessible at `/api/v1/kyc/verifications/90`. It uses the x402 payment protocol, accepting USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the endpoint.

The broader lowpaymentfee.com platform advertises a range of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model and settle on the Base network using USDC.

Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the KYC verification endpoint actually accepts or returns. The endpoint path includes an ID segment (`/90`) whose meaning is unclear — it may represent a specific verification type or a resource identifier. Callers should expect to POST JSON but will need to experiment or contact the provider to determine the required request body and response format.

Quality

0.25/ 1.00

The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation, no request/response examples, and the purpose of the '/90' path segment is unknown. The docs pages are all empty wallet-connect stubs. This is effectively a stub listing.

Warnings

  • —No documentation available — /docs, /api, /pricing, and /README all return only a wallet-connect prompt
  • —No OpenAPI or request/response schema provided; request body and response format are unknown
  • —The path segment '/90' is unexplained — unclear if it's a verification type ID or resource identifier
  • —KYC/identity verification is a regulated category; verify the provider's compliance posture before use
