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 statement data behind an x402 paywall. The specific resource `/api/v1/accounts/27/statements` is a POST endpoint that returns JSON account statements. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) 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 translates to $0.02 per call, consistent with the site-wide pricing of $0.02/request advertised on the provider's landing page. No API keys are required; authentication and payment happen entirely through the X-PAYMENT header. The provider advertises no rate limits and instant access.
The provider (lowpaymentfee.com) hosts a broader catalog of x402-gated APIs spanning data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all at the same $0.02/request price point. However, this specific listing covers only the `/api/v1/accounts/27/statements` endpoint. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs. The purpose of 'account statements' for account 27 is unexplained, making it unclear what data is actually returned.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content.
- —The endpoint targets a hardcoded account ID (27); it is unclear whether this is a demo or a real resource.
- —No request body schema or response schema is documented anywhere.
- —No examples of actual response payloads are available to verify functionality.
