x402-gated account statements endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/100/statements` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto market data, and utility services (geocoding, validation, conversion, generation), all priced at $0.02 per request. However, the specific endpoint cataloged here is the account statements resource. The exact schema of the request body and response payload is not documented in the crawled material, so callers should expect to discover the format experimentally or via additional documentation not currently available.
The endpoint is live and returned a proper 402 challenge when probed. The site's landing page loads successfully (HTTP 200), though the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive documentation.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond a landing page listing. The actual purpose and data format of the 'account statements' resource is unclear.
