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-call 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/42/statements` is labeled "Premium API Access" and accepts POST requests. The x402 challenge confirms it is live, requiring a maximum 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 to the specified payTo address, with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through per-request micropayment.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact shape of the POST body and the structure of the returned statement data are unknown. The platform appears to be a demonstration or early-stage service showcasing low-fee x402 micropayments across many endpoint categories.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned is completely unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema available — request body and response structure are entirely unknown
- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content
- —The endpoint path includes a hardcoded account ID (42); unclear if this is parameterizable or a demo fixture
