## 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 agent402-tools-crypto-market-brief-ff4350d1 -d '<json body>'
```

Example prompt: Give me a full crypto market brief for ethereum — including its current price, what coins are trending right now, and the global stats like total market cap, BTC dominance, and 24h volume.

## When to prefer this

Use this endpoint when you need a comprehensive crypto market snapshot in a single call — combining a specific coin's price, trending coins, and global stats — rather than making three separate API calls. Ideal for dashboards, daily briefings, or any agent workflow where crypto market context is needed efficiently with one x402 micropayment.

## Known failure modes

- Invalid or unknown coin id returns an error or empty price field
- CoinGecko API downtime may cause partial or failed data retrieval
- Insufficient x402 payment balance causes 402 Payment Required rejection
- Malformed request body missing the coin field may return a validation error

## How this service works

Bundled execution of the Crypto market brief workflow - Quick crypto market snapshot: price for a specific coin, trending coins, and global market stats (total cap, BTC dominance, volume) - one call. One x402 payment runs 3 underlying tools (crypto-price, crypto-trending, crypto-global); partial-success per step.

## Output

Returns the spot price for the requested coin, a list of currently trending coins, and global market statistics including total market capitalization, Bitcoin dominance percentage, and 24-hour trading volume — all in one response from a single x402 payment.
