## 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 gadgethumans-research-api-0ab161e1
```

Example prompt: Can you research the topic of quantum computing for me and give me a solid summary of what it is, how it works, and where it's headed?

## When to prefer this

Choose this endpoint when you need a quick, AI-synthesized research summary on any topic without requiring a specific data source or structured database. It is best for broad knowledge retrieval tasks where the goal is a readable summary rather than structured data. It is part of a multi-tool hub, so prefer it when you want a low-cost ($0.005 USDC), no-API-key-needed research call.

## Known failure modes

- Missing or empty topic parameter returns an error
- Topic too vague or broad may return generic results
- Payment failure (x402) results in 402 Payment Required
- Rate limiting on free tier may block repeated calls
- Response schema is minimal ({ok:true}) so actual content structure may vary
