## 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 nova-ai-inference-api-pipeline-47d66fce -d '<json body>'
```

Example prompt: Using Nova's AI inference pipeline, run this two-step pipeline: first translate my input text 'Hello, how are you today?' into Spanish, then summarize the result — and execute it now.

## When to prefer this

Choose this endpoint when you need a pay-per-call, crypto-native (USDC on Base) AI inference pipeline that supports chaining multiple steps (chat, translation, reasoning, analysis, generation) in a single call without a subscription commitment.

## Known failure modes
