Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #193) via an x402 pay-per-call model. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or subscriptions are required — each call is individually paid through the x402 payment header.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint being listed here — /api/v1/employees/193 — is not documented on the provider's landing page among the advertised APIs. Its exact response schema and the nature of the employee data it returns are unknown; the listing title simply says "Premium API Access."
Because the endpoint is live (returning a valid 402 challenge) but lacks documentation, response examples, or an OpenAPI spec, consumers should treat this as a lightly-documented data endpoint. The payment mechanics are well-defined via the x402 challenge, but the data payload is opaque.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing, but there is no OpenAPI spec, no response schema, no documentation for this specific endpoint, and it does not appear in the provider's own advertised API list. The data returned is entirely opaque.
