x402-gated employee data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an employee record (ID 22) behind an x402 payment wall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).
The provider lowpaymentfee.com hosts a broader catalog of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all advertised at $0.02 per request with no API keys, no rate limits, and instant access. However, this specific listing is for the /api/v1/employees/22 endpoint, which is not listed on the provider's landing page catalog. Its exact response schema and the nature of the employee data it returns are undocumented.
The endpoint is live: the probe received a proper HTTP 402 challenge with a well-formed x402 v1 payment envelope. No OpenAPI spec, detailed documentation, or example responses were found in the crawl — the docs, pricing, API, and README pages all returned only a "Connect wallet" stub. This limits confidence in what the endpoint actually returns beyond the generic "Premium API Access" description.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no documented response schema, no example responses, and the endpoint itself (/api/v1/employees/22) is not listed in the provider's own catalog. Documentation pages are all stubs. The nature of the data returned is unknown.
