x402-payable account statements endpoint on Base, settled in USDC at $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/33/statements` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme. The max amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD.
The provider, lowpaymentfee.com, operates a broader platform offering multiple x402-gated API categories including data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. However, this specific endpoint (`/accounts/33/statements`) is not listed on the provider's landing page among the advertised APIs, so its exact functionality and response schema are unclear. The title "Premium API Access" is generic and does not describe what data the statements endpoint actually returns.
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 request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation makes it difficult to determine what input the POST body expects or what the response contains.
