x402-payable account statements endpoint on Base, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides account statement data via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all settled on the Base network using USDC.
The specific endpoint `/api/v1/accounts/1/statements` is labeled "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment on Base. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request — consistent with the platform's uniform $0.02/request pricing shown on its landing page.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema, no request/response examples, and no detailed documentation describing what fields the statements endpoint returns or what parameters it accepts. The endpoint is live (returns a valid 402 challenge), but the lack of documentation makes it difficult to know what data is actually returned.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are gated behind wallet connection with no readable content. The purpose and output of the 'accounts/1/statements' endpoint is unclear beyond its title.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —All doc pages (/docs, /pricing, /api, /README) render only a 'Connect wallet' prompt with no usable content
- —The endpoint path includes a hardcoded account ID ('1'), and it is unclear whether other account IDs are supported or what parameters the POST body accepts
- —No response examples or field descriptions are available — integration requires trial-and-error
