## 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 lion-research-agent-7e6418ac -d '<json body>'
```

Example prompt: Can you do a deep research on the current state of quantum computing hardware and give me a structured breakdown with key findings, sources, and how confident you are in the results?

## When to prefer this

Choose this endpoint when you need structured, citation-backed research output with an explicit confidence rating — particularly useful for agent pipelines that need to reason about result reliability or pass findings downstream in a structured format rather than raw web search results.

## Known failure modes

- Missing required 'query' field returns a 400 or validation error
- Vague or ambiguous query may produce low confidence score
- External sources unavailable may reduce source count and lower confidence
- Payment not provided or insufficient USDC may result in 402 payment required error
- Network timeout if underlying research process takes too long

## How this service works
