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 164) 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 (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. However, this specific listing covers only the `/api/v1/employees/164` resource, which appears to be a sample or demonstration employee-record endpoint.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no description of request parameters or response fields, and no usage examples beyond what can be inferred from the x402 challenge. 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. However, there is no OpenAPI schema, no documentation of request/response fields, no examples, and the docs pages are empty. The endpoint path (/employees/164) suggests a demo or sample resource with unclear real-world utility.

- —No OpenAPI or schema describing request parameters or response structure
- —The endpoint targets a single hardcoded employee ID (164); unclear if other IDs are available or what the data contains
