x402-gated account statements endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statements via a POST request to `/api/v1/accounts/189/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all gated behind the x402 payment protocol on the Base network.
The specific endpoint probed returns a 402 challenge requesting payment in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base). The `maxAmountRequired` is 20,000 base units, which at 6 decimals for USDC equals $0.02 per request. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through on-chain micropayment.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what the statements endpoint actually returns or what parameters it accepts. The endpoint is live and the x402 challenge is well-formed, but without documentation it is difficult to know what data is returned or how to structure a meaningful request body.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no indication of what the statements endpoint actually returns. The specific path (/accounts/189/statements) appears to be a hardcoded account ID with no explanation. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The endpoint path includes a hardcoded account ID (189) with no explanation of what account this refers to
- —Unknown request body format — no input schema documented
- —Cannot verify what data the endpoint actually returns
