Example prompt: Can you generate a set of differentiated headline variants for my residential door installation company in Dallas? My brief is that we require a consultation before quoting, we only do entry doors, and our tone is practical and clear — please group them by angle like consultation focus, location clarity, and brand voice, and flag any unsupported claims.

## When to prefer this

Choose this endpoint when you need multiple distinct marketing headline options generated from a structured brief, especially when you want them organized by strategic angle with built-in rationale and unsupported-claim review — ideal for copywriters, marketers, or agents automating content workflows who need more than a single headline suggestion and want a compliance-aware output before human review.

## Known failure modes

- Brief too short (below 10 characters) returns validation error
- Source text or brief exceeds character limits causing rejection
- Insufficient source material leads to thin or generic headlines with many evidence gaps flagged
- Ambiguous audience descriptor may produce misaligned angle groupings
- Network timeout on large source text payloads

## How this service works

Produce differentiated headlines grouped by angle, with rationale and unsupported-claim checks. Uses buyer-supplied information only; no external research or outbound actions. Returns a draft for human review.

## Output

A JSON object containing grouped headline variants organized by angle (e.g. consultation focus, service/location clarity, availability, brand voice), along with rationale for each group, an unsupported-claim check, a list of assumptions made, evidence gaps identified, and a flag indicating whether human review is recommended before publishing.
