Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/56/salary` returns salary information for employee ID 56 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. The endpoint was confirmed live, returning a proper 402 challenge with x402 version 1.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the salary endpoint returns or what input it expects beyond a POST method. The endpoint path suggests it retrieves salary data for a specific employee by numeric ID, but the exact request body format and response structure are unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response examples, and all doc pages show only 'Connect wallet'. The purpose of this specific endpoint (employee salary data) is only inferrable from the URL path. The broader site catalog suggests a pattern but provides no detail on this resource.
Warnings
- —No OpenAPI schema or endpoint documentation available
- —All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content
- —Request body format and response schema are completely unknown
- —The endpoint path '/employees/56/salary' is very specific — unclear if other employee IDs are supported or if this is a demo resource
- —Provider legitimacy and data source are unverifiable from available materials
