x402-payable account statements endpoint on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides account statement data behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/18/statements` accepts POST requests and returns JSON. The x402 challenge confirms it is live, requiring a payment of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 USD. Payment is made via the x402 "exact" scheme to the payee address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, with a 300-second timeout window.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api, /README) all resolve but contain only a "Connect wallet" prompt with no substantive content, so the actual request/response schema for this statements endpoint is unknown. The endpoint's purpose — account statements — suggests financial or accounting data, but without documentation or example payloads, the exact fields and capabilities cannot be confirmed.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no documentation, no request/response schema, and no examples available. The docs, pricing, and API pages are all empty stubs showing only 'Connect wallet'. The purpose of the specific /accounts/18/statements path is unclear beyond the generic 'Premium API Access' label.
Warnings
- —No API documentation available — all doc pages return only a 'Connect wallet' prompt with no content
- —Request body schema and response schema are completely unknown
- —The endpoint path includes a hardcoded account ID (18), suggesting it may be account-specific rather than general-purpose
- —Platform appears to be a demo or early-stage project with many listed endpoints but no substantive documentation
