## 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 sitecheck-web-intel-dappradar-top-50-rankings-c542a990
```

Example prompt: Can you pull the top 25 dapps from DappRadar for the Ethereum chain over the last 7 days, including their token price, market cap, UAW, and TVL?

## When to prefer this

Use this endpoint when you need a quick, no-API-key snapshot of the top dapps ranked by DappRadar, especially when you need UAW, TVL, token price, and volume across multiple time periods. Prefer this over direct DappRadar API integrations when you want a simple GET call without authentication. Best for lightweight dapp discovery, market monitoring, and cross-chain comparisons.

## Known failure modes

- DappRadar page structure changes causing parse failures
- Chain slug not recognized — returns empty or error response
- Limit out of range (>50 or <1) may return default or error
- Network timeout if DappRadar public page is slow or unavailable
- Missing values (null) for dapps without token listings or TVL data

## How this service works

Top 50 dapps from DappRadar's public rankings page: rank, name, token symbol, chains, market cap, token price, price change, trading volume, unique active wallets (UAW) and TVL, for 24h/7d/30d, optionally for one chain (eth, solana, bnb, base, polygon, arbitrum, tron...). Values in USD as shown by DappRadar; missing values are null. Public page, no key.

## Output

Returns a ranked list of up to 50 dapps with fields including rank, name, token symbol, supported chains, market cap (USD), token price (USD), price change percentage, 24h/7d/30d trading volume, unique active wallets (UAW), and total value locked (TVL). Missing values are returned as null. All monetary values are in USD as displayed by DappRadar.
