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/92`. 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.
The broader lowpaymentfee.com platform offers a range of pay-per-request APIs spanning data & analytics, AI & machine learning (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 required.
Note that while the endpoint is live and returns a valid x402 challenge, the specific KYC verification path (`/verifications/92`) is not listed among the documented APIs on the landing page, and no documentation exists describing the expected request body or response schema for this endpoint. The docs, pricing, and API pages behind the site all appear to require wallet connection and provide no additional technical detail.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation for the KYC verification endpoint—no request schema, no response schema, no examples. The docs pages are empty behind a wallet-connect gate. The specific path /api/v1/kyc/verifications/92 is not listed on the landing page, making its purpose and input/output entirely opaque.
Warnings
- —The endpoint path /api/v1/kyc/verifications/92 is not listed among the documented APIs on the provider's landing page.
- —No request or response schema is available; input format is unknown.
- —All documentation pages (docs, pricing, API, README) are gated behind wallet connection and contain no useful content.
- —KYC/identity verification is a regulated category—verify the provider's compliance posture before relying on results.
- —The hardcoded ID '92' in the path is unexplained; it may refer to a specific verification record rather than a general-purpose endpoint.
