x402-payable account statements endpoint on Base, $0.02/request in USDC.
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, settled in USDC on the Base network.
The specific resource `/api/v1/accounts/91/statements` appears to return financial account statement information (JSON). Payment is handled via the x402 protocol: callers receive a 402 challenge containing the accepted payment scheme (exact), the USDC asset contract on Base (`0x8335…`), and a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). No API keys or rate limits are advertised; access is granted per-request upon valid payment.
Documentation on the site is extremely thin — the docs, pricing, API, 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 fields the statements endpoint returns or what POST body it expects. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes integration speculative.

Quality
The endpoint is confirmed live via a valid 402 challenge, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond a landing page listing. The purpose of the specific /accounts/91/statements resource is unclear — it may be a demo or placeholder. Score reflects minimal usable information.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The endpoint path includes a hardcoded account ID (91), suggesting it may be a demo or placeholder
- —No request body schema or response schema is documented anywhere
- —The platform lists many diverse API categories but provides no evidence any return real data
