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 via the x402 payment protocol. The specific resource `/api/v1/kyc/verifications/60` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled inline via the x402 header challenge — no API keys, accounts, or rate limits are required.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-request 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 is not listed on the site's public landing page, and no documentation describing its input schema, required fields, or response format was found in the crawl. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.
Because no input/output schema, example payloads, or detailed documentation are available for this endpoint, integrators will need to experiment or contact the provider to determine the expected POST body and response structure. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation is a significant gap.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is no documentation, no input/output schema, no examples, and the specific KYC endpoint is not even listed on the provider's landing page. This is effectively a stub listing with only pricing and liveness confirmed.
Warnings

- —The /api/v1/kyc/verifications/60 path is not listed among the provider's publicly advertised APIs
- —All documentation pages (docs, pricing, API, README) returned only a 'Connect wallet' prompt with no content
- —The meaning of the path segment '60' is unclear — it may be a verification type ID or a resource identifier
