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 behind an x402 paywall. The specific resource `/api/v1/employees/76/salary` returns salary information for employee ID 76 in JSON format. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint is live and returns a valid x402 challenge (HTTP 402) with a maximum amount of 20,000 base units. Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the provider's advertised flat pricing of $0.02/request across all their APIs. The provider advertises no API keys, no rate limits, and instant access. The payment timeout is 300 seconds.
lowpaymentfee.com hosts a broader catalog of x402-gated APIs spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all at the same $0.02/request price point. However, this specific listing covers only the employee salary endpoint. Documentation beyond the landing page is essentially empty (pages return only "Connect wallet"), so the exact request body schema and response format are unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation on request body schema, response format, or what data fields are returned. The docs, pricing, API, and README pages all render only 'Connect wallet' with no useful content. The endpoint path suggests employee salary data but nothing confirms the actual payload structure.
Warnings
- —No request body schema or response schema documented anywhere
- —All documentation pages (docs, api, pricing, README) are empty beyond 'Connect wallet'
- —The nature of the 'employee salary' data is unclear — it may be demo/synthetic data
- —No OpenAPI spec or AI plugin manifest available
