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/115/statements` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a max amount of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach an X-PAYMENT header with a valid payment proof.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what "account statements" contain or what parameters the POST body accepts. The endpoint's purpose and data model must be inferred entirely from its URL path and the generic platform description.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page listing, and no examples. The specific purpose of 'account statements for account 115' is opaque. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body format and response structure are completely unknown

- —The endpoint path references a hardcoded account ID (115); it is unclear whether this is a demo or a real account
