## 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 api-strale-io-583f52ac
```

Example prompt: Draft me a cold outreach email to a VP of Engineering at a mid-size SaaS company — I want to pitch our developer tooling product, keep the tone confident but not pushy, and make sure the subject line is compelling enough to get opened.

## When to prefer this

Choose this endpoint when you need to quickly generate a structured, professional email with subject line variants and key phrases — especially for common business scenarios like cold outreach, follow-ups, or apologies. Prefer this over general-purpose LLM prompting when you want a specialized output format that includes subject options and key phrases in a single structured response.

## Known failure modes

- Missing required 'context' query parameter returns a 400 error
- Vague or extremely short context may produce generic, low-quality output
- Unsupported intent or tone values may fall back to defaults or return validation errors
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Rate limiting or overload may return a 503 error

## Output

Returns multiple subject line options, a complete email body, and a set of key phrases — all tailored to the specified context, intent type (cold outreach, follow-up, apology, etc.), and tone.
