## 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 inkbox-extract-terms-c89b3d8b -d '<json body>'
```

Example prompt: Pull out the key terms and important phrases from this article: 'Quantum computing leverages superposition and entanglement to perform calculations that classical computers cannot efficiently solve, with applications in cryptography, drug discovery, and optimization problems.'

## When to prefer this

Use this endpoint when you need to automatically identify and extract the most significant terms, keywords, or phrases from a body of text — ideal for SEO keyword discovery, content tagging, topic modeling, or building glossaries from documents. Prefer this over a general summarization endpoint when the goal is a discrete list of terms rather than a prose summary.

## Known failure modes

- Missing required 'text' field returns a 400 or error response
- Empty string input may return empty terms list or error
- Very short or uninformative text may yield few or no terms
- Payment failure (402) if USDC on Base is not provided or insufficient
- Rate limiting or service unavailability returns 5xx errors
