/**
* Authenticated Usage Example - Audit Proof Circuit
*
* This example demonstrates how to use the Audit Proof circuit
* with the AffixIO SDK in production mode with API authentication.
*
* ⚠️ IMPORTANT: This example requires an API key from AffixIO.
* Get your API key at: https://dashboard.affix-io.com
*
* Prerequisites:
* - npm install @affixio/sdk
* - npm install typescript @types/node ts-node
* - Get an API key from https://dashboard.affix-io.com
* - Set AFFIXIO_API_KEY environment variable or replace the placeholder
*
* Run with:
* AFFIXIO_API_KEY=affix_xxxxx npx ts-node examples/authenticated-usage.ts
