x402-payable account statements endpoint on Base, settling 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-request 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/86/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335… 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 an X-PAYMENT header with a valid payment proof.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what "account 86 statements" actually contains. The endpoint is live (402 challenge confirmed), but without documentation it is difficult to know what data is returned or what POST body is expected.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what 'account 86 statements' actually represents. No OpenAPI spec, no examples, and all doc pages are empty. The listing is essentially a stub.

- —No OpenAPI or schema definition for request or response bodies
