x402-payable account statements endpoint on Base, settling in USDC at $0.02/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 request and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/139/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach an X-PAYMENT header with a valid payment proof.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint returns or what parameters it accepts. The endpoint is confirmed live (402 challenge captured), but the actual functionality behind the paywall is opaque from available materials.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect prompt. The actual functionality of the statements endpoint is unknown, making this effectively a stub listing.
Warnings
