Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary information for a specific employee (ID 27) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and no upfront commitments — callers simply attach an x402 payment header to each request.
The provider (lowpaymentfee.com) hosts a broader catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request on the Base network. However, this specific listing covers only the `/api/v1/employees/27/salary` endpoint. The x402 challenge was successfully captured (HTTP 402 with a valid accepts block), confirming the endpoint is live.
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 example payloads available. The exact structure of the salary response and what POST body (if any) is expected are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of this specific employee-salary endpoint is opaque. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no technical content
- —This endpoint targets a single hardcoded employee ID (27); generalizability is unclear
- —Provider description is generic ('Premium API Access') with no endpoint-specific detail
