## 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-data-coingecko-powered-batched-price-feed-d5c06eed
```

Example prompt: Pull the full market snapshot for BTC, ETH, and SOL — I need current price, market cap, 24h volume, 24h high and low, and the all-time-high with date for each.

## When to prefer this

Choose this endpoint when you need rich, multi-field crypto market data (market cap, supply, ATH, 24h OHLCV) for multiple coins in a single batched call — especially when plain price-feed APIs return null for market cap. Prefer over standard stock-data crypto tickers, which often lack market cap and supply data. Ideal for portfolio dashboards, comparative analysis, or any agent task requiring more than just a spot price.

## Known failure modes

- Invalid or unrecognized ticker symbol returns null or error for that symbol
- Missing 'symbols' query parameter causes a 400 bad request
- Payment not included or insufficient causes a 402 Payment Required response
- Rate limits or CoinGecko upstream outages may cause 503 or timeout
- Some fields (e.g. max supply) may be null for tokens with no hard cap

## How this service works

Real crypto market data in one batched call: price, market cap, market-cap rank, 24h volume/high/low/change, circulating/total/max supply, and all-time-high with date -- for BTC, ETH, SOL, and 17+ other major coins by ticker. Richer than a plain price feed: most stock-data APIs' crypto tickers report null market cap. From CoinGecko. $0.005/call.

## Output

A batched JSON response keyed by ticker symbol, each containing: current price, market cap, market cap rank, 24h volume, 24h high, 24h low, 24h price change (absolute and percent), circulating supply, total supply, max supply, all-time-high price, and all-time-high date — sourced from CoinGecko.
