Query AAVE wallet balances via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns AAVE token wallet balance data, paid per-call using the x402 protocol. The payment is settled in USDC on the Base network at a cost of $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the data.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/wallet/AAVE/balance` falls under the Finance & Web3 category and is designed to return balance information for the AAVE token. The endpoint accepts POST requests and returns JSON.
Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of required parameters or response fields. The x402 challenge is live and well-formed, confirming the endpoint is operational, but the lack of documentation makes it difficult to know what request body (if any) is expected or what the response structure looks like.

Quality
The x402 challenge is live and well-formed, confirming the endpoint is operational at $0.02/request in USDC on Base. However, documentation is essentially nonexistent — no OpenAPI schema, no request/response examples, and no parameter descriptions. The request body and response format are entirely inferred.
Warnings
- —No documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no technical content
- —No OpenAPI or schema definition for request or response bodies
- —Example request JSON is speculative — the actual required parameters are unknown
- —The broader site lists many API categories but it is unclear how mature or complete each endpoint is
