Pay-per-call account statements API on Base network via x402 protocol, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements data via a POST request, paid per-call using the x402 protocol. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities, all priced at $0.02 per request. The specific endpoint `/api/v1/accounts/137/statements` appears to serve account-level financial statement data, though detailed documentation on request/response schemas is not publicly available.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. It accepts POST requests and returns application/json responses. The payment is routed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.
