x402-gated employee salary endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 172) via an x402 payment challenge. It is part of a broader platform offering numerous pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 micropayments on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum amount required per call is 20,000 base units, which at 6 decimals equals $0.02. The platform advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured, 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 substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains or what input the POST body expects. The endpoint's purpose (employee salary lookup) is inferred solely from the URL path. The broader platform lists many endpoints at $0.02 each, but none have documented schemas.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the endpoint's actual data content is entirely inferred from the URL path. This is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or input/output schema provided; request body format and response fields are unknown
- —The endpoint path suggests employee-specific salary data but this is unverified — no sample responses exist
- —The broader platform lists many endpoints but none appear to have documented schemas
