x402-payable account statements endpoint on Base, settled in USDC at $0.02 per 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 call and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/22/statements` accepts POST requests and returns JSON. The x402 challenge confirms it is live, requiring a maximum of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request. Payment is made via the x402 exact scheme to the specified payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is granted purely through on-chain micropayment.
Documentation is extremely sparse. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint's purpose (account statements) is inferred solely from the URL path and the generic "Premium API Access" label. Prospective users should expect to experiment with the endpoint to discover its input/output contract.

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 contract of the /accounts/22/statements endpoint is unknown.
Warnings
