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/80/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 maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is granted purely through per-request micropayments.
The provider, lowpaymentfee.com, hosts a broader catalog of x402-gated APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto data feeds, and utility services — all priced at $0.02 per request. However, the specific endpoint listed here is scoped to account statements. Documentation beyond the landing page is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail.
Because there is no OpenAPI schema, no request/response examples, and no documentation describing what fields the statements endpoint accepts or returns, the actual functionality and data format remain unclear. The endpoint is confirmed live (402 challenge captured), but consumers should expect to experiment with request payloads to discover the accepted input format.

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. The /docs, /pricing, and /README pages are empty beyond a wallet-connect prompt. The purpose of 'account statements' for account ID 80 is unexplained, making this effectively a stub listing.
Warnings
- —No API documentation available — /docs, /api, /pricing, and /README pages all show only 'Connect wallet' with no technical content.
- —No request or response schema provided; input format and output fields are unknown.
- —The endpoint path references a hardcoded account ID (80); it is unclear whether other account IDs are accessible or what data is returned.
- —The broader site advertises many API categories (AI, finance, utilities) all at $0.02, but none have visible documentation, raising questions about actual functionality.
