x402-gated employee salary endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 126) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the provider's site-wide flat pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access; the only authentication is the x402 payment header.
The broader lowpaymentfee.com platform lists many other x402 endpoints spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all at the same $0.02 price point. However, this specific endpoint (/api/v1/employees/126/salary) is not listed on the provider's landing page among the advertised APIs, and no documentation describes what fields the salary response contains or what the POST body should look like. The endpoint is live (returns a valid 402 challenge), but the actual response schema and input parameters are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, but it is not listed among the provider's advertised APIs, has no documentation, no input/output schema, and the crawled docs/pricing/README pages are all blank beyond a 'Connect wallet' prompt. Effectively a stub with confirmed liveness.
