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/130` sits within a broader platform that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints on the platform 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 for this endpoint confirms it is live and accepts exact-scheme payments of up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payments are sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The endpoint accepts POST requests and returns application/json.
The exact functionality behind `/api/v1/accounts/130` is not documented beyond the label "Premium API Access." The platform's docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical documentation, OpenAPI spec, or example payloads. Without additional documentation it is unclear what data or service this specific account endpoint returns. The broader platform advertises analytics, AI inference, finance data, and utility endpoints, but this particular path does not map to any of those listed categories.
