## 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 scrapling-x402-live-crypto-top-500-markets-dataset-216f1e64
```

Example prompt: Pull the latest live market data for the top 500 cryptocurrencies — I need current price, 24h volume, market cap, and how far each coin is from its all-time high, returned as JSON.

## When to prefer this

Choose this endpoint when you need a broad, pre-aggregated snapshot of the top 500 crypto markets in a single paid call, rather than querying individual coin APIs or assembling data from multiple sources. It is especially useful when you need structured, ranked market data including ATH metrics, supply figures, and multi-timeframe price changes all in one response. Prefer it over free alternatives when freshness and completeness across 500 assets matter and you can tolerate a $0.49 USDC per-call cost.

## Known failure modes

- Payment not settled — 402 returned if x402 payment header is missing or insufficient
- Invalid format enum value — returns error if format query param is not one of json/jsonl/csv/markdown
- Network or upstream data source unavailable — may return 503 or stale data
- Rate limiting or wallet-level abuse detection — repeated calls from same address may be throttled

## Output

Returns a JSON (or CSV/JSONL/Markdown) dataset of 500 records, each containing the coin's name, symbol, CoinGecko ID, rank, current USD price, 24h high/low, 1h/24h/7d percentage changes, all-time high price and drawdown percentage, market cap, 24h volume, circulating supply, fully diluted valuation, and a timestamp of when the source data was last updated.
