Query Aave DeFi positions via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to Aave DeFi position data through the x402 payment protocol. It accepts POST requests and returns JSON responses containing Aave lending/borrowing position information. 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).
The provider operates a broader platform offering multiple API categories including data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced uniformly at $0.02 per call. The platform advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment challenges with x402 version 1.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what parameters the Aave positions endpoint accepts or what fields it returns. The endpoint path suggests it retrieves Aave protocol positions (likely supply/borrow balances for a given address), but the exact request format and response structure must be inferred.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation: no OpenAPI schema, no request/response examples, and no description of accepted parameters or returned fields. The request and response examples are entirely inferred from the endpoint path name. This is effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all return only a wallet-connect prompt
- —No OpenAPI or JSON schema provided for request or response
- —Request body format is entirely inferred from the endpoint path; actual required parameters are unknown
- —Response structure is unknown — example_response_json is null
