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/118` 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 particular endpoint confirms it is live, accepting POST requests, and requires payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to wallet address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. 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/118` endpoint is unclear. The platform's landing page lists various API categories but does not include an "accounts" endpoint in its public catalog. No OpenAPI schema, detailed documentation, or example request/response payloads are available — the docs, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. As a result, the exact input parameters and output format for this endpoint remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge, confirming pricing and payment details. However, the specific purpose of /api/v1/accounts/118 is undocumented, no request/response schema is available, and all documentation pages render only a wallet-connect prompt with no content. This is effectively a stub listing.
