## 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 tempest-ai-signal-post-generator-4d4d75ea -d '<json body>'
```

Example prompt: Write me a LinkedIn post about the future of remote work with a professional tone — make it feel authoritative and thought-leadership focused.

## When to prefer this

Use this endpoint when you need to quickly generate platform-aware social media posts (Twitter, LinkedIn, Instagram) with tone control at $0.30 per call via USDC micropayment. Prefer it over general-purpose LLM calls when you want a dedicated, pay-per-use content API without managing prompt engineering for each platform.

## Known failure modes

- Missing required 'topic' field returns validation error
- Invalid platform value may produce generic output
- Network timeout on Vercel serverless cold start
- Payment failure via x402 USDC returns 402 before content is generated
- Ambiguous or very short topic may produce low-quality output
