Example prompt: Can you check how visible my brand 'Morning Bloom Coffee' (morningbloom.com) is in AI answer engines like ChatGPT and Perplexity — I want to see the score, which competitors are winning instead, and what I should fix first?

## When to prefer this

Choose this endpoint when you need a quick, scored assessment of a brand's presence in AI answer engines (ChatGPT, Claude, Perplexity) with actionable GEO recommendations. It is purpose-built for generative engine optimization audits, not traditional SEO or web search rankings. Prefer it over generic brand monitoring tools when the question is specifically 'does AI recommend us to buyers?'

## Known failure modes

- Missing required 'brand' field returns a validation error
- Unknown or very obscure brands may return low scores with limited question data
- Ambiguous brand names without URL or category may yield inaccurate competitor mapping
- Network timeouts if AI engine queries take too long
- $4 USDC payment failure or insufficient balance blocks the call
