# CryptoRank Projects List

Fetches a ranked list of top cryptocurrency projects with real-time price, market cap, volume, and supply data from CryptoRank

## 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 cryptorank-projects-list-655bbf4a
```

Example prompt: Pull the top 20 cryptocurrencies from CryptoRank and show me their current prices, 24-hour volume, and market caps.

## When to prefer this

Use this endpoint when you need a ranked list of top crypto assets with comprehensive market metrics (price, volume, market cap, ATH, supply) in a single call and want pay-per-use access with no API key or subscription required. Prefer this over exchange-specific APIs when you need cross-asset rankings rather than a single coin's data.

## Known failure modes

- Invalid limit value (outside 1–100 range) may return an error or default
- Payment failure via x402 if insufficient USDC balance; failed calls are not charged
- Upstream CryptoRank API unavailability may cause stale or missing data
- Rate limiting or quota exhaustion on the underlying CryptoRank data source

## How this service works

CryptoRank top crypto projects by rank: name, symbol, type, price, market cap, fully diluted valuation, 24h volume, 24h high/low, supply and all-time high, from CryptoRank's API v2. Up to the top 100.

## Output

Returns a JSON object with a count, source URL, checkedAt timestamp, and an array of crypto project objects each containing: key, name, rank, type, symbol, priceUsd, low24hUsd, high24hUsd, maxSupply, lastUpdated, marketCapUsd, volume24hUsd, allTimeHighUsd, allTimeHighDate, circulatingSupply, and fullyDilutedValuationUsd.
