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 an employee record (ID 169) via the x402 payment protocol. It accepts POST requests and returns JSON. 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).
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 priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are handled entirely through the x402 protocol on the Base L2 network.
The specific endpoint `/api/v1/employees/169` appears to serve a single employee record. No OpenAPI schema, request body specification, or response schema was found in the crawled material. The docs, pricing, and README pages all rendered only a "Connect wallet" prompt with no additional documentation. As a result, the exact request format and response structure for this endpoint are unknown and must be discovered by the caller.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, and all doc pages render only a wallet-connect prompt. The specific purpose of the /employees/169 resource is opaque.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown
- —All documentation pages (docs, pricing, README) returned only a 'Connect wallet' prompt with no useful content
- —The endpoint serves a single hardcoded employee ID (169); unclear if other IDs are available or what the data contains
