## When to prefer this

Use this endpoint when an agent needs to programmatically generate a QR code from a URL or text string without requiring an API key, paying per-call in USDC on Base via x402 protocol. Prefer over alternatives when operating in a crypto-native or Web3 payment context, or when avoiding API key management overhead.
