x402-payable employee salary lookup endpoint on Base, settled in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via an x402 payment-gated API. The specific resource `/api/v1/employees/37/salary` returns salary information for employee ID 37 when called with an HTTP POST and a valid X-PAYMENT header. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with an exact-scheme challenge requiring up to 20,000 base units (i.e., $0.02 USD given USDC's 6 decimals).
The hosting provider lowpaymentfee.com offers a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The employee salary endpoint is not prominently listed on the landing page catalog, so its exact response schema and data source are unclear. The x402 challenge confirms the endpoint is live and accepts POST requests, returning application/json content.
Because there is no OpenAPI spec, no documented request/response schema for this specific endpoint, and the crawled docs/pricing/README pages returned only a wallet-connect prompt with no additional content, the actual data returned and its accuracy cannot be verified from available materials alone.

Quality
