## 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-content-engine-social-signal-generator-d61e99fe -d '<json body>'
```

Example prompt: Write me a professional LinkedIn post about the rise of AI agents in enterprise software — keep the tone optimistic and forward-looking.

## When to prefer this

Choose this endpoint when you need to quickly generate platform-specific social media posts at scale with tone control, especially in automated content pipelines or agent workflows that require pay-per-call flexibility without a subscription. Prefer it over general LLM calls when you want pre-tuned social media formatting for Twitter, LinkedIn, or Instagram.

## Known failure modes

- Missing required 'topic' field returns an error response
- Invalid or unsupported platform value may produce generic output
- Vague or very short topic may yield low-quality or off-brand content
- Network or server timeout on the Vercel deployment
- Payment failure via x402/USDC prevents request from completing
