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 ID 179) behind a micropayment wall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge of 20,000 base units, which equals $0.02 per request (USDC uses 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 catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints appear to share the same $0.02/request pricing model. However, this specific listing covers only the `/api/v1/employees/179` endpoint, which is categorized under what appears to be a sample or demo employee record resource.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint is confirmed live (402 challenge captured), but the actual data payload and its usefulness remain unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the purpose of an 'employees/179' endpoint is unclear. This is effectively a stub listing.
Warnings
- —No documentation available — all doc pages return only 'Connect wallet' with no content
- —No OpenAPI or schema describing request parameters or response fields
- —The endpoint targets a single hardcoded employee ID (179); unclear if this is a demo or production resource
- —No information on what data fields are returned in the employee record
