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/26/statements`. It is part of a broader platform offering 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 requires a maximum payment of 20,000 base units of USDC (contract `0x8335…2913` on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain to address `0x1A2B…85F3` with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely via the x402 payment header.
The platform's landing page lists additional endpoint categories including sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, and more — all at the same $0.02 price point. However, documentation pages (`/docs`, `/pricing`, `/api`, `/README`) returned only a "Connect wallet" prompt with no substantive content, so the actual request/response schemas for this or any endpoint remain undocumented. The endpoint is confirmed live (402 challenge returned successfully), but without schema details or example payloads, integration requires experimentation.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, and no examples. The docs, pricing, API, and README pages all render only a wallet-connect prompt. The purpose of 'account statements' for 'account 26' is unexplained.
Warnings
- —No API documentation available — /docs, /pricing, /api, and /README pages all return only a 'Connect wallet' prompt with no content.
- —Request and response schemas are completely unknown; no OpenAPI spec or examples provided.
- —The endpoint path references a specific account ID (26), and it is unclear whether this is parameterized or fixed.
- —The broader platform advertises many endpoint categories (AI, finance, utilities) all at $0.02, but none have documented schemas — treat with caution.
