x402-gated account statements endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/19/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services.
The specific endpoint probed returns account statement data in JSON format. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maximum amount of 20,000 base units, which at 6 decimals for USDC equals $0.02 per request — consistent with the platform's uniform $0.02/request pricing displayed on its landing page.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api, /README) all returned minimal content (just a "Connect wallet" prompt), so there is no detailed schema documentation, request/response examples, or further technical guidance available. The endpoint is live and responding with a valid x402 challenge. The exact structure of the statement data returned after payment is not documented.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response documentation, no examples, and all doc pages are empty stubs. The purpose of the specific '/accounts/19/statements' resource is unclear beyond the generic 'Premium API Access' label.
Warnings
- —No API documentation available — /docs, /pricing, /api, and /README pages all return only a 'Connect wallet' prompt with no technical content.
- —The exact request body schema and response format for this endpoint are undocumented; integration requires trial-and-error or contacting the provider.
- —The endpoint path includes a hardcoded account ID (19), which may indicate a demo or single-tenant resource rather than a general-purpose API.
