x402-payable employee salary lookup endpoint on Base, settled in USDC at $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via an x402 payment-gated API. The specific resource `/api/v1/employees/104/salary` returns salary information for employee ID 104 when called with a POST request and a valid x402 payment header. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broad catalog of x402-payable 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 — payment is the only authentication mechanism. However, documentation is extremely sparse: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail.
Because there is no OpenAPI schema, no request/response examples, and no documentation beyond the landing page listing, the actual structure of the salary response body is unknown. The endpoint is confirmed live (returns a proper 402 challenge), but callers will need to experiment to determine what fields are returned and what input the POST body expects.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing, but there is zero documentation on request/response schemas, no OpenAPI spec, and the docs pages are empty. The purpose of the endpoint (employee salary data) is only inferable from the URL path. This is effectively a stub listing.
Warnings
- —No OpenAPI schema or request/response documentation available
- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no content
- —The actual response format and required POST body fields are completely unknown
- —The endpoint path suggests access to personal salary data — consider data privacy implications
- —This appears to be a demo/showcase site; the authenticity and source of employee salary data is unverified
