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/193/statements`. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, 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 on Base using USDC (contract `0x8335…2913`) with the "exact" scheme. The platform advertises a flat $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and instant access.
Documentation is extremely sparse — the /docs, /pricing, /api, 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 the "account statements" resource actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data to send or what response to expect.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what data the endpoint actually provides. The docs pages are all blank 'Connect wallet' stubs.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; it is unknown what POST body to send or what the response contains.
- —The specific resource path '/api/v1/accounts/193/statements' references a hardcoded account ID (193); unclear if this is a demo or a real resource.
- —The platform lists many diverse API categories (AI, finance, infrastructure) at uniform $0.02 pricing with no visible documentation — exercise caution.
