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/37/statements`. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, 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 to the specified wallet address using the "exact" scheme. The platform advertises a uniform $0.02/request pricing across all its endpoints, with no API keys, no rate limits, and no minimum commitments required.
The endpoint returned a valid 402 challenge confirming it is live and operational. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the "account statements" resource actually returns or what input parameters it expects. The endpoint's purpose (account statements for account ID 37) is unclear without further documentation.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is no OpenAPI schema, no documentation, no request/response examples, and no explanation of what 'account statements' actually returns. The docs pages are all empty 'Connect wallet' stubs. This is effectively a stub listing.
Warnings
- —No API documentation available — all doc pages render only 'Connect wallet' with no content
- —No OpenAPI or input/output schema provided; request parameters and response format are unknown
- —The specific resource '/api/v1/accounts/37/statements' references a hardcoded account ID (37) with no explanation of what it represents
- —The platform lists many endpoints on its homepage but none have documented schemas or examples
