Pay-per-call employee salary lookup API on Base via x402 (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request, settled per-call using the x402 payment protocol on the Base network with USDC. The specific resource `/api/v1/employees/12/salary` returns salary information for employee ID 12. The x402 challenge confirms the endpoint is live and accepts payments of up to $0.02 per request (20,000 base units of USDC with 6 decimals = $0.02).
The provider lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. Payments settle on the Base L2 network using USDC (contract 0x8335...2913). No OpenAPI schema or detailed documentation was found beyond the landing page listing; the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
Because the endpoint path references a specific employee ID and the description is simply "Premium API Access," the exact response schema and the full set of available employee endpoints are unknown. The endpoint is confirmed live via a valid 402 challenge, but the lack of documentation means callers must discover the response format empirically.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, but there is no OpenAPI schema, no response examples, and no meaningful documentation (all doc pages return only 'Connect wallet'). The endpoint path suggests a demo/sample resource (employee 12) with unclear real-world utility. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (/docs, /pricing, /README, /api) returned no content beyond 'Connect wallet'
- —The endpoint path references a hardcoded employee ID (12); it is unclear whether other IDs are supported or what the broader API surface looks like
- —The 'Premium API Access' description is generic and does not describe the actual data returned
- —No rate limit or SLA information available
