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 #88) 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, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints appear to share the same $0.02/request pricing model on Base. However, the specific endpoint being listed here (/api/v1/employees/88) is not prominently documented on the provider's landing page, and no detailed schema or example response is available for it.
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 spec, no response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data returned after payment is unknown.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no response schema, no example payloads, and the /employees/88 path is not documented on the provider's site. Documentation pages are effectively empty. This is a stub-level listing.
