## 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 primeapi-ai-expand-d64c1a87 -d '<json body>'
```

Example prompt: Can you expand this short idea into a more detailed description: 'sustainable urban farming using vertical gardens'?

## When to prefer this

Use this endpoint when you need to take a short text snippet, keyword, or concept and have AI expand it into a richer, more detailed response — especially when you want a pay-per-call model with no API key setup. Prefer this over general-purpose LLM APIs when operating within an x402/USDC micropayment workflow on Base.

## Known failure modes

- Empty or missing query field returns an error or empty response
- Query too long may be truncated or rejected
- Payment failure (402) if USDC balance is insufficient or x402 protocol handshake fails
- Generic 500 error if the AI backend is unavailable
- Vague or ambiguous query may produce low-quality or off-topic expansion

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

An AI-generated expanded version of the input query — a longer, more detailed or elaborated text response based on what was submitted in the query field.
