x402-gated account statements endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/157/statements` is described as "Premium API Access" and accepts POST requests, returning JSON responses. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the site-wide $0.02/request pricing advertised on the provider's landing page. The provider advertises no API keys, no rate limits, and instant access; callers simply attach an X-PAYMENT header with a valid x402 payment proof.
lowpaymentfee.com hosts a broader catalog of x402-gated APIs spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/crypto (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints share the same $0.02/request pricing model. However, this specific listing covers only the `/api/v1/accounts/157/statements` resource. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the purpose of 'account statements' for account 157 is entirely opaque. This is effectively a stub listing.
Warnings

- —The specific resource '/api/v1/accounts/157/statements' is unexplained — unclear what account 157 refers to or what data is returned
