Pay-per-call premium API access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific resource `/api/v1/accounts/156` is one of many endpoints offered by the platform, which spans categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints are priced at $0.02 per request, payable in USDC on the Base network with no API keys, rate limits, or commitments required.
The x402 challenge confirms the endpoint is live, accepting POST requests and settling payments in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base). The max amount required is 20,000 base units, which at 6 decimals equals $0.02. The payment scheme is "exact" with a 300-second timeout. The response MIME type is `application/json`.
However, the specific functionality of the `/api/v1/accounts/156` endpoint is unclear. It does not appear in the site's listed API catalog, which covers analytics, AI, finance, and utility endpoints. There is no OpenAPI schema, no request/response documentation, and the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional content. The actual data returned by this particular endpoint is unknown.
