## 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 crypto-market-brief-for-agents-ebd2a224
```

Example prompt: Give me the current crypto market brief — total market cap, BTC and ETH dominance, prices and recent moves for BTC, ETH, SOL and XRP, the latest Bitcoin and XRP ETF flows, and any macro or crypto events coming up in the next 48 hours.

## When to prefer this

Choose this endpoint when an agent needs a comprehensive, ready-to-use crypto market context object at the start of a trading, portfolio, or research loop — especially when you need dominance metrics, multi-timeframe price moves, ETF flow data, and a forward event calendar all in one parameter-free call rather than assembling them from multiple specialized endpoints. It is ideal when speed and simplicity matter more than deep historical data or per-coin granularity.

## Known failure modes

- Payment failure if x402 USDC micropayment is not completed — endpoint returns 402 Payment Required
- Network timeout if the Blockchain IQ backend is temporarily unavailable
- Stale data risk if the 1-minute refresh cycle is delayed on the provider side
- Malformed JSON if an upstream data source feed is interrupted

## How this service works

Market brief in one parameter-free call: BTC, ETH, SOL and XRP prices with 24h, 7d and 30d moves and rank, scheduled macro and crypto events in the next 48 hours, and short risk flags. Use as the opening call of a trading, portfolio or research agent loop. Refreshed every minute. JSON, no API key. $0.01 per call. Blockchain IQ.

## Output

A JSON object containing: total crypto market cap and 24h percentage change; Bitcoin and Ethereum dominance percentages; current USD prices for BTC, ETH, SOL, and XRP each with 24h, 7d, and 30d percentage moves; Bitcoin and XRP spot-ETF net flow figures for the latest session and trailing 7 days; a list of scheduled macro and crypto events in the next 48 hours; and short-form risk flags summarizing the current market regime.
