Pay-per-call employee data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves employee data (specifically record #28) via a POST request, paid per-call with USDC on the Base network. The endpoint returns a 402 challenge requiring an X-PAYMENT header with an exact payment scheme. The maximum amount required is 20,000 base units of USDC (0.02 USD, i.e., two cents per request).
The provider lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data & analytics, AI/ML (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 advertised at $0.02 per request with no API keys, no rate limits, and no commitments — payment is handled entirely through the x402 protocol on Base.
Documentation is extremely sparse. The docs, API, pricing, 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 employee endpoint actually returns. The endpoint is live (402 challenge confirmed), but the lack of documentation makes it difficult to know what data to send or what shape the response takes.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only 'Connect wallet' with no content. The purpose of the /employees/28 endpoint is unclear beyond the generic 'Premium API Access' label. Effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or output schema describing request parameters or response shape
- —The specific endpoint /api/v1/employees/28 is not listed on the provider's homepage catalog, raising questions about its intended use
- —Cannot confirm what data is returned without making a paid request
