Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #54) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broader suite 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 technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific data returned by the /api/v1/employees/54 endpoint is unknown beyond the stated mime type of application/json. The endpoint is confirmed live (returns a proper 402 challenge).

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing, but there is zero documentation on request parameters, response schema, or what employee data is actually returned. The docs, pricing, and README pages are all empty beyond a wallet connect prompt. This is effectively a stub listing.
Warnings
- —No OpenAPI spec or schema documentation available
- —No example request or response payloads — the actual data returned is unknown
- —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content
- —The specific meaning of employee record #54 is unexplained
- —Provider hosts many diverse API categories (AI, finance, geo, etc.) all at $0.02 — unclear if these are real production services or demonstrations
