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 91) 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 hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance & Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. However, this specific endpoint (`/api/v1/employees/91/salary`) is not listed on the site's public catalog, and no documentation beyond the x402 challenge was found. The response schema, request body format, and exact data returned are undocumented. The crawled docs, pricing, API, and README pages all rendered only a "Connect wallet" prompt with no additional content.
Because the endpoint is live (returns a valid 402 challenge with x402 version 1) and the payment parameters are clear, agents can integrate it, but the lack of input/output schema documentation means callers must discover the expected POST body experimentally. The endpoint pays to wallet 0x1A2B...85F3 and accepts the canonical Base USDC contract (0x8335...2913).

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing and payment parameters. However, there is no OpenAPI schema, no documented request/response format, no examples, and the endpoint is not listed in the provider's own public catalog. Docs pages returned only wallet-connect prompts with no usable content.
