Pay-per-call employee salary lookup API on Base via x402, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request, paid per call using the x402 protocol. The specific resource `/api/v1/employees/123/salary` returns salary information for employee ID 123 in JSON format. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request.
The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced uniformly at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an x402 payment header to each request. The x402 challenge confirms the endpoint is live and accepting payments to address 0x1A2B...85F3 on Base.
Documentation is extremely sparse. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples. The endpoint path suggests it returns salary data for a specific employee, but the exact request body format and response structure are unknown. Treat this listing as a stub until richer documentation becomes available.

Quality
The x402 challenge is live and confirms pricing and network, but there is zero documentation beyond the landing page listing. No OpenAPI spec, no request/response schema, no examples. The endpoint path is specific (employee 123) with no guidance on parameterization. Effectively a stub.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are entirely unknown.
- —Docs, pricing, API, and README pages all render only 'Connect wallet' with no technical content.
- —The endpoint path hardcodes employee ID 123; it is unclear how to query other employees.
- —No information on data source, accuracy, or whether this returns real or mock data.
