x402-gated account statements endpoint on Base, pay $0.02 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/173/statements` is a POST endpoint that returns JSON account statements. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme.
The provider operates a broader platform offering multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an X-PAYMENT header with a valid x402 payment proof. The max amount required for this endpoint is 20,000 base units of USDC (6 decimals), which equals $0.02 USD.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact structure of the POST body and the response format for account statements are unknown. The endpoint is confirmed live (returns 402 with a valid x402 challenge).

Quality
The endpoint is confirmed live with a valid x402 challenge, but documentation is essentially nonexistent — docs/pricing/API pages only show 'Connect wallet'. There is no OpenAPI spec, no request/response schema, and no examples. The purpose of 'account statements' for account 173 is opaque. This is effectively a stub listing.
Warnings
- —No API documentation available — all doc pages render only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The specific resource '/api/v1/accounts/173/statements' is not listed on the provider's homepage; its purpose and data contents are unclear
- —No examples of request body or response format available
