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/112/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 charges up to 0.02 USDC per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals). Payment is settled on-chain via the x402 "exact" scheme to a designated wallet address. The platform advertises no API keys, no rate limits, and instant access — the only requirement is an x402-compatible payment header. The endpoint accepts POST requests and returns `application/json`.
Documentation on the site is extremely thin: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the statements endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what request body to send or what shape the response takes.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC per request). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The purpose of the specific '/accounts/112/statements' path is unclear — it may be a demo or placeholder. This is effectively a stub listing.
Warnings
- —No API documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The endpoint path '/api/v1/accounts/112/statements' includes a hardcoded account ID (112); unclear if this is a demo or a real resource
- —The broader platform lists many API categories but none have documented schemas or examples
- —Cannot verify what data the endpoint actually returns without making a paid request
