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 data for a specific employee (ID 102) 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 — you simply attach an X-PAYMENT header with a valid x402 payment proof.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model and x402 payment flow on Base.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint actually returns. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know the exact request body format or response shape without experimentation.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The specific purpose of the salary endpoint is only inferable from the URL path. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown
- —All doc/pricing/README pages render only 'Connect wallet' with no technical content
- —The endpoint path suggests employee salary data, but no formal description confirms what fields are returned
- —This appears to be a demo/showcase site; data authenticity and reliability are unverified
