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. The specific resource `/api/v1/accounts/51/statements` is accessed via POST and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises a wide catalog of x402-payable 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 at the same $0.02/request price point. However, this specific listing covers only the account statements endpoint.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint is confirmed live via a valid 402 challenge, but the actual functionality and data format remain unclear.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the purpose of 'account statements' for 'account 51' is entirely unexplained. This is effectively a stub listing.
Warnings
- —No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content
- —No OpenAPI or input/output schema provided; request body format and response structure are unknown
- —The endpoint path references a specific account ID (51) with no explanation of what this account represents or whether other account IDs are valid
- —The broader platform claims many API categories (AI, finance, infrastructure) but none have documented schemas
