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/114/salary` returns salary information for employee ID 114 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.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens 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. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment-gated requests.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint's actual data content (what fields are returned for a salary lookup) must be inferred from the resource path alone. The employee ID 114 appears hardcoded in the URL, suggesting individual employee lookups are path-parameterized.

Quality
The x402 challenge is live and confirms pricing and network details, but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no example payloads. The endpoint's actual data content is entirely unknown beyond what the URL path implies.

- —The employee ID 114 is hardcoded in the listed URL; it is unclear whether other IDs are valid or how to discover them
