x402-gated employee salary lookup 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 155) via an x402 payment-gated POST request. It is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call API endpoints across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.
The x402 challenge confirms the endpoint is live and accepts payments via the "exact" scheme on Base mainnet. The maximum amount required is 20,000 base units of USDC (0x8335…2913), which equals $0.02 per request (USDC uses 6 decimals). The platform advertises uniform $0.02/request pricing with no API keys, no rate limits, and no minimum commitments.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint returns or what input it expects beyond an HTTP POST. The endpoint path suggests it returns salary information for a specific employee record, but the actual payload structure is unknown.

Quality
The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, no meaningful documentation (all doc pages show only 'Connect wallet'), and the purpose of this specific employee salary endpoint is opaque. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are entirely unknown.
- —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content.
- —The endpoint path references a specific employee ID (155); it is unclear whether other IDs are supported or what data is returned.
- —The nature of the 'employee salary' data is unverified — it could be sample/demo data.
