## When to prefer this

Choose this endpoint when you need automated auditing of advertising spend data to catch waste, anomalies, or budget misallocations — especially in agentic workflows where ad spend data needs to be reviewed programmatically without a human analyst.

## Known failure modes

- Empty or malformed data string returns an error or empty analysis
- Unstructured or unsupported data formats may yield low-quality results
- Insufficient data context may produce generic rather than actionable recommendations
- Network or payment authorization failures return a 402 or 5xx HTTP error
