x402-gated account statements endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/9/statements`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind the x402 payment protocol on the Base network.
The specific endpoint listed here returns account statement data in JSON format. Payment is settled in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base) at a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). The platform advertises no API keys, no rate limits, and instant access — callers simply attach an x402 payment header to each request.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint is confirmed live (returns a valid 402 challenge), but the actual functionality behind the paywall is unverifiable from public information alone.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts USDC on Base. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The purpose of 'account statements' for 'account 9' is entirely opaque.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or input/output schema provided; request body format and response structure are unknown.
- —The endpoint path includes a hardcoded account ID ('/accounts/9/statements') — unclear if this is parameterizable or a fixed demo resource.
- —Actual data returned behind the paywall cannot be verified from public crawl data.
