## 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 coinpaprika-tickers-via-sitecheck-crypto-finance-626eb543
```

Example prompt: Pull the latest market data for the top 20 cryptocurrencies — I want to see current prices in USD, market caps, 24-hour volume, and how much each coin has moved in the last hour, 24 hours, and 7 days.

## When to prefer this

Choose this endpoint when you need broad cryptocurrency market overview data — ranked prices, market caps, volumes, and short-term percent changes for multiple coins at once — without requiring an API key or subscription. It is ideal for agents doing pay-per-call crypto monitoring, portfolio snapshots, or trend detection across the top coins. Prefer this over on-chain lookups when you want aggregated market-level data rather than raw transaction or wallet data.

## Known failure modes

- Invalid limit parameter (outside 1-100 range) may return an error or default response
- Payment failure results in no charge and no data returned
- CoinPaprika upstream unavailability may cause stale or missing data
- Network timeout on the Cloudflare Worker edge may result in a 503 or gateway error

## How this service works

CoinPaprika top crypto tickers by market rank: USD price, 24h volume, market cap and percent changes (1h, 24h, 7d). The first N coins by rank, N from 1 to 100.

## Output

A JSON object containing an array of coin objects (up to 100), each with coin ID, name, symbol, rank, USD price, market cap in USD, 24h volume in USD, and percent changes for 1h, 24h, and 7d intervals, along with a count, the source URL (CoinPaprika), and a checkedAt timestamp.
