## 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 dt0ur-online-crypto-market-brief-11f200de -d '<json body>'
```

Example prompt: Give me a full market brief for BTC — I want the current price, 24h change, funding rate, open interest, Fear and Greed index, and any signals about crowded longs or shorts.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one crypto market snapshot for a single coin in one API call, rather than stitching together spot price, derivatives, and sentiment data from multiple sources. Particularly valuable for agents building trading dashboards, daily briefings, or pre-trade checklists where funding rates, open interest, Fear & Greed, and plain-language signals are all needed together. Best suited for the 50 major coins enumerated in the schema.

## Known failure modes

- Unsupported coin ticker returns validation error — only the 50 enumerated tickers are accepted
- Downstream exchange data unavailable may return stale or partial data
- Network timeout if exchange APIs are slow to respond
- Invalid request body (missing 'coin' field) returns a 400 bad request

## How this service works

One-call market brief for a coin (BTC, ETH, SOL, HYPE and 45+ majors): USD price and 24h change, spot 24h high/low/volume and bid/ask, perpetual funding rate (APR), open interest and perp-vs-spot basis, the Crypto Fear & Greed index, and plain-language signals (crowded longs/shorts, big moves).

## Output

A structured JSON response containing: current USD price and 24h percentage change, spot 24h high/low/volume and best bid/ask prices, perpetual funding rate expressed as APR, open interest in USD, perp-vs-spot basis, the Crypto Fear & Greed index value, and plain-language signals such as 'crowded longs', 'crowded shorts', or 'big move detected'.
