## 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 nexusapi-ai-text-expand-22cc3f6d -d '<json body>'
```

Example prompt: Can you expand this short phrase into a full, detailed paragraph: 'blockchain benefits for supply chain'?

## When to prefer this

Choose this endpoint when you need to quickly elaborate a short text, keyword, or query into a longer form using AI, without setting up your own LLM infrastructure or API keys. It is particularly useful for content enrichment pipelines, drafting marketing copy from brief inputs, or generating research summaries from keywords, and it accepts micropayments per call in USDC on Base without requiring account setup.

## Known failure modes

- Empty or missing query field returns a validation error
- Extremely long input may be truncated or rejected
- Vague or ambiguous queries may produce generic or off-topic expansions
- Payment failure (402) if USDC balance is insufficient
- Service unavailability returns a 5xx error from the Vercel deployment
