## 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-pulse-endpoint-bfd6481b -d '<json body>'
```

Example prompt: Run this paragraph through Tempest's pulse endpoint and tell me what it finds: 'Our Q3 revenue grew 18% year-over-year, driven primarily by enterprise subscription upgrades and expansion into APAC markets.'

## When to prefer this

Choose this endpoint when you need fast, pay-per-call AI text analysis without a subscription commitment. It is part of a larger 25-endpoint AI content suite (Tempest), so it is best suited for workflows already integrated with the Tempest ecosystem or when USDC micropayment billing via x402 is preferred over monthly API key plans.

## Known failure modes

- Missing required 'text' field returns a validation error
- Empty string input may return empty or null data
- Very long text inputs may exceed token or size limits
- Payment failure (insufficient USDC) blocks request processing
- Network timeout from the Vercel-hosted service under load
- Malformed JSON body returns a 400-level error
