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/197/statements` is a POST endpoint that returns JSON account statements. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the provider's site-wide flat pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge specifies a maximum timeout of 300 seconds.
The broader lowpaymentfee.com platform lists additional API categories including data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all at the same $0.02/request price point. However, this specific listing covers only the `/api/v1/accounts/197/statements` endpoint. Documentation pages on the site appear to be stub pages requiring wallet connection, so detailed request/response schemas are not available.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and the documentation pages are empty stubs. The purpose of 'account statements' for account 197 is vague and unexplained.
Warnings
- —No OpenAPI or request/response schema available — input and output formats are unknown
- —Documentation pages (/docs, /api, /pricing, /README) are all empty stubs showing only 'Connect wallet'
- —The endpoint references a specific account ID (197) with no explanation of what account data is served or how to access other accounts
- —The broader platform lists many API categories but none have documented schemas
