x402-payable account statements endpoint on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides account statement data behind an x402 paywall. 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 priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/145/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach the X-PAYMENT header with a valid payment proof.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the statements endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what input parameters are expected or what shape the response takes.

Quality
The endpoint is confirmed live via a valid 402 challenge, but documentation is essentially nonexistent — all doc pages render only 'Connect wallet'. There is no OpenAPI spec, no request/response examples, and no description of what 'account statements' actually contains. The endpoint path includes a hardcoded account ID (145), raising questions about generality. Pricing is clear ($0.02/request in USDC on Base).
Warnings
- —No API documentation available — all doc pages show only 'Connect wallet'
- —No OpenAPI or schema definition for request parameters or response format
- —The endpoint path contains a hardcoded account ID (145); unclear if other account IDs are supported or what data is returned
- —No request or response examples exist in any crawled material
- —The nature of the 'statements' data is completely undocumented
