Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #157) via the x402 payment protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) 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 broader lowpaymentfee.com platform advertises a wide 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 share the same $0.02/request pricing model and Base-network USDC settlement.
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 spec, no request/response schema documentation, and no example payloads available. The specific data returned by the /api/v1/employees/157 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, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schemas, no examples. The purpose of the /employees/157 endpoint is unclear beyond the generic 'Premium API Access' label. The score reflects a live but poorly documented stub.
Warnings
- —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content
- —No OpenAPI or schema definition; request body format and response structure are completely unknown
- —The specific data returned by /api/v1/employees/157 is undocumented — 'Premium API Access' is the only description
- —The endpoint path suggests a single hardcoded employee record (#157); unclear if this is a demo or production resource
