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 records via a simple HTTP POST, gated by the x402 payment protocol. The specific resource `/api/v1/employees/50` returns JSON data for employee ID 50. 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). No API keys or rate limits are required — access is granted purely through the x402 payment header.
The provider, lowpaymentfee.com, hosts a broader 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 listed at $0.02 per request with the same x402 payment model on Base.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the employee endpoint returns. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response payload structure is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and documentation pages are effectively empty. The actual data returned is completely unknown, making this largely a stub listing.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README pages only show 'Connect wallet' with no content
- —No OpenAPI or schema definition for request or response payloads
- —Unknown response structure — it is unclear what fields the employee endpoint returns
- —The endpoint path suggests a demo/sample resource (employee ID 50); unclear if other IDs are supported
