Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #37) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The provider, lowpaymentfee.com, hosts 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 are priced uniformly at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are made inline via the x402 protocol's X-PAYMENT header.
The specific endpoint `/api/v1/employees/37` is not listed on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear. No OpenAPI spec, detailed documentation, or example responses were found during the crawl — the docs, pricing, and README pages all returned only a "Connect wallet" prompt. The endpoint is confirmed live (returning a valid 402 challenge), but the lack of documentation about what employee data is returned and where it originates warrants caution.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, this specific employee endpoint is not listed in the provider's own catalog, no OpenAPI spec exists, no documentation was retrievable (all pages returned only 'Connect wallet'), and there are no example responses or schema details for the employee data returned. Effectively a stub listing.
