## How to call it through Zero

```sh
zero fetch --capability questflow-b25d08e2 -d '<json body>'
```

Example prompt: Can you break down my goal of launching a small e-commerce store into manageable steps and delegate each part to the right specialized agents?

## When to prefer this

Choose this endpoint when a user has a complex, multi-step goal that needs to be broken down into actionable sub-tasks and potentially handed off to specialized agents. Ideal for project planning, workflow orchestration, and any scenario where a single agent cannot handle all aspects of a task alone.

## Known failure modes

- Missing X-PAYMENT header returns 402 with payment requirements
- Missing required 'input' field in request body returns validation error
- Task too vague or ambiguous may result in generic or unhelpful decomposition
- Agent delegation failure if no suitable specialized agents are available
- Timeout if task decomposition is computationally intensive
