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 22) 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 provides instant access — callers simply attach an x402 payment header to authorize each call.
The endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/employees/22/salary`) is not prominently advertised on the provider's landing page among those categories, so its exact response schema and data source are unclear. The x402 challenge confirms it is live and accepting payments.
No OpenAPI spec, detailed documentation, or example responses were found during the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content. This limits confidence in what the endpoint actually returns beyond the generic "Premium API Access" description.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation, no example responses, and the endpoint path (employees/22/salary) is not listed among the provider's advertised APIs. The crawled docs/pricing/API pages were empty beyond a wallet-connect prompt. Effectively a stub listing.
