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-ff6ccda0 -d '<json body>'
```

Example prompt: Write me a professional LinkedIn post about the future of remote work — make the tone optimistic and forward-looking.

## When to prefer this

Choose this endpoint when you need to programmatically generate platform-specific social media posts at scale with tone control. It is especially useful for marketing automation agents, content scheduling pipelines, or AI assistants helping users craft social media copy quickly. Prefer it over generic LLM prompting when you want a purpose-built, pay-per-call API with consistent social post formatting across Twitter, LinkedIn, and Instagram.

## Known failure modes

- Missing required 'topic' field returns a validation error
- Invalid or unsupported platform value may produce generic output not optimized for any platform
- Payment failure via x402/USDC results in 402 Payment Required before content is generated
- Vague or very short topics may produce low-quality or generic posts
- Rate limiting or Vercel cold-start may cause latency spikes or timeouts
