Pay-per-call customer data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to a "Premium API Access" resource at the path `/api/v1/customers/48`. It is part of a broader platform offering multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
The endpoint uses the x402 payment protocol on the Base network, accepting USDC (USD Coin, contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payments are sent to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds. The endpoint accepts HTTP POST requests and returns `application/json`.
The specific `/api/v1/customers/48` path suggests a customer record lookup, but the crawled documentation provides no details about the request body schema, response fields, or what "customer 48" represents. The broader site lists many endpoints but the docs, pricing, and README pages all render only a "Connect wallet" prompt with no further technical documentation. Without an OpenAPI spec, example requests/responses, or detailed field descriptions, the exact behavior of this endpoint remains unclear.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of /api/v1/customers/48 is not explained. Effectively a stub listing.
