x402-gated account statements endpoint on Base, pay $0.02 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/121/statements`. It is part of a broader platform offering dozens of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request settled in USDC on the Base network.
The endpoint uses the x402 payment protocol (version 1, "exact" scheme). When called without payment, it returns a 402 challenge advertising a max amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is `application/json`.
The specific endpoint path (`/accounts/121/statements`) suggests it returns financial statement data for a particular account. However, no detailed documentation, request schema, or response schema is available — the docs, pricing, and API pages on the site all render only a "Connect wallet" prompt with no further content. Because of this, the exact request body format and response structure are unknown. The platform advertises no API keys, no rate limits, and instant access, with all payments handled on-chain via the Base network.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and payment details. However, there is no OpenAPI schema, no request/response documentation, and the docs pages are empty ("Connect wallet" only). The specific purpose of account 121 statements is unclear, and no example payloads are available.
Warnings
- —No API documentation available — docs, pricing, and API pages all render only 'Connect wallet' with no content.
- —No request body schema or response schema documented; integration requires trial and error.
- —The endpoint path references a specific account ID (121); it is unclear whether other account IDs are supported or what data is returned.
- —The broader platform lists many endpoints but none have documented schemas.
