## 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 wealth-agent-brief-research-question-answering-685c8ecc
```

Example prompt: Can you research what the current outlook is for REITs in a high-interest-rate environment and give me a sourced one-page brief with key findings and any gaps in the data?

## When to prefer this

Choose this endpoint when you need a sourced, structured research brief on any open-ended question — especially financial, investment, or wealth-related topics — and want findings with citations and explicit knowledge gaps rather than a raw web search dump. Prefer this over general-purpose search when you want a synthesized one-page answer with provenance, not just a list of links.

## Known failure modes

- Question is missing or outside the 5–400 character limit — returns error
- Question is too vague for meaningful research — may return sparse findings
- Underlying research sources unavailable — may return 'paid_not_delivered' status
- Payment not confirmed — 402 Payment Required before research is executed
- Rate limiting or worker timeout on complex queries

## How this service works

Returns a one-page research brief with cited source URLs, key findings and open gaps for a question. Call it when an agent needs a sourced answer instead of an unsourced guess. Input: {"question": "..."} (5-400 chars, any language).

## Output

Returns a JSON object with a 'deliverable' containing: a plain-language summary answering the question, an array of findings each with citations, a list of source URLs and titles, a list of gaps (things that could not be verified), and a status confirming delivery. Also includes a resource identifier and a boolean ok flag.
