x402-gated account statements endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/118/statements`. It is part of a broader platform that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network.
The specific endpoint probed here charges up to $0.02 per request (20,000 base units of USDC, which has 6 decimals). Payment is settled on-chain via USDC (contract `0x8335…2913` on Base) to the payee address `0x1A2B…85F3`. The x402 challenge uses the "exact" scheme with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through per-call micropayments.
Documentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no explanation of what the statements endpoint actually returns or what parameters it accepts. The endpoint is confirmed live (returns a valid 402 challenge), but without documentation it is difficult to know what data it provides or how to structure a request body beyond the POST method.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is zero documentation: no OpenAPI spec, no request/response schema, no description of what 'account statements' actually contains. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The specific resource path '/api/v1/accounts/118/statements' includes a hardcoded account ID (118); it is unclear if this is parameterizable or a fixed demo
- —Purpose and data content of 'account statements' is not described anywhere in the crawled material
