## How to call it through Zero

```sh
zero fetch --capability first-fold-conversion-brief-4e599dd6
```

Example prompt: Can you run a First Fold conversion brief for Northstar HVAC — we install heat pumps for homeowners replacing aging heating systems, targeting cost-conscious homeowners aged 40–65, their main problem is not knowing which system to pick, the outcome they want is a clear written installation plan, and the CTA is to request a planning call? Use a direct tone, and our proof points are: licensed in 3 states; 500+ installs; average project quote in 48 hours.

## When to prefer this

Choose this endpoint when an agent needs a ready-to-implement homepage strategy document for a local service business — especially when the user has a defined offer, audience, and CTA but needs structured positioning, headline options, and a prioritized build order. Prefer this over generic copywriting endpoints when the output must include conversion hierarchy, A/B test hypotheses, and message readiness scoring in a single structured response. Best suited for single-page homepage briefs rather than multi-page site audits or ad campaigns.

## Known failure modes

- Missing required query parameters (brand, offer, audience, problem, outcome, action) returns a validation error
- Invalid tone enum value causes a schema error
- Overly vague inputs (e.g. single-word audience or problem) may yield low message readiness scores and generic output
- Payment not fulfilled (x402) results in 402 Payment Required with no brief returned
- Extremely long input strings exceeding field limits may be truncated or rejected

## How this service works

Conversion-focused homepage rebuilds for local service businesses. One page, one revision, $225 flat.

## Output

A JSON object containing: a message readiness score (0–100) with interpretation, a one-line positioning statement, multiple hero headline variants each with angle, headline, and CTA, a recommended page hierarchy with section jobs, prioritized A/B test hypotheses, an ordered implementation checklist, content guardrails, and optional FAQ drafts and objection-handling blocks.
