x402-gated account statements endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/200/statements` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The provider's landing page advertises a broad catalog of x402-gated APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and instant access. The probed endpoint's x402 challenge shows a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site's advertised pricing.
Documentation is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples. The endpoint is live (returns a valid 402 challenge), but the actual data returned after payment and the expected POST body are unknown from available materials.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation of request body or response schema, and the docs pages are empty. The purpose of the specific '/accounts/200/statements' resource is only inferable from the URL path.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown.
