## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability exepal-ai-brand-visibility-a0e7ae20 -d '<json body>'
```

Example prompt: How visible is Notion on AI answer engines like ChatGPT, Perplexity, and Google compared to competitors Evernote and Obsidian in the US note-taking apps category? Run 10 prompts to measure it.

## When to prefer this

Choose this endpoint when you need to quantitatively measure how often a brand appears in AI-generated answers across multiple LLMs simultaneously, especially for competitive benchmarking. Prefer this over manual SERP monitoring when the goal is AI engine share-of-voice rather than traditional search ranking. Ideal for marketing teams, brand managers, or AI agents tasked with tracking AI discoverability without managing API keys or subscriptions.

## Known failure modes

- Invalid or unsupported engine names return validation errors
- Exceeding promptCount tier cap truncates results or returns an error
- Unrecognized brand domain may reduce accuracy of results
- Payment failure via x402 results in 402 response and no data
- Ambiguous category string may produce off-topic prompts reducing accuracy

## How this service works

## Output

Returns a structured report showing the brand's mention rate and visibility score across the specified AI engines, broken down by engine, compared against the listed competitors within the given product category and market. Likely includes share-of-voice percentages, prompt-level results, and a competitive ranking.
