Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

Example prompt: Can you run this draft blog intro through the Tempest AI pulse endpoint and rewrite it to sound more engaging and professional: 'We help businesses grow their online presence through digital marketing solutions.'

## When to prefer this

Choose this endpoint when you need pay-per-call AI text transformation without a subscription commitment, especially for sporadic or bursty content workloads. Prefer it over managed SaaS writing tools when you want programmatic control via API and are comfortable paying per call in USDC. Best suited for agents that need to compose, rewrite, or analyze text as part of a larger automated workflow.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty or very short text may yield poor AI output quality
- Payment failure (insufficient USDC) blocks the call via x402 protocol
- Rate limiting or model unavailability may cause transient failures
- Ambiguous or malformed text input may result in unexpected data shape in response
