## 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 pyfile-toolkit-crypto-defi-network-analyst-brief-ccfa5458
```

Example prompt: Give me a quick analyst brief on the DeFi topic — pull live yield data and give me a summary with key facts and your take, focused on stablecoin opportunities.

## When to prefer this

Choose this endpoint when you need a fast, opinionated analyst summary combining live market data with LLM-generated narrative — ideal for agents that need a human-readable briefing rather than raw data. Best for crypto, DeFi, or blockchain network topics where a structured facts + summary format is needed. Prefer over raw price APIs when interpretation and synthesis matter.

## Known failure modes

- Invalid topic value (not crypto|defi|network) — may return error or empty response
- Live data source unavailable — summary may be incomplete or stale
- LLM composition failure — no summary returned
- Rate limit or payment failure — 402 response requiring USDC payment
- Network timeout fetching live data — delayed or partial response

## How this service works

Analyst brief on a topic: gathers live data (crypto prices, DeFi yields, network status) and returns an LLM-composed summary with key facts and a take. ?topic=crypto|defi|network&focus=<optional text>

## Output

Returns a JSON object containing: a `summary` string with an LLM-composed analyst take, a `facts` object with structured key data points (prices, yields, metrics), a `sources` array listing the data sources used, and a `topic` string confirming the queried topic.
