Scrape Tokens

Automate token market data collection from CoinGecko and CoinMarketCap using the agent-browser CLI.

Prerequisites

  • agent-browser CLI installed and accessible
  • Run agent-browser --help to verify installation

Core Workflow

Step 1: Scrape CoinGecko

Navigate to CoinGecko:

bash
agent-browser open https://www.coingecko.com/

Take snapshot to identify elements:

bash
agent-browser snapshot -i

CoinGecko provides:

  • Top cryptocurrencies by market cap
  • 24h price changes
  • Trading volume
  • Market cap rankings
Step 2: Extract Token Data (CoinGecko)

For the main token list, extract:

FieldDescription
rankMarket cap ranking
nameToken name
symbolToken symbol (BTC, ETH)
priceCurrent price in USD
change_24h24-hour price change %
change_7d7-day price change %
market_capMarket capitalization
volume_24h24-hour trading volume

JavaScript extraction pattern:

javascript
const tokens = [];
document.querySelectorAll('table tbody tr').forEach(row => {
  const cells = row.querySelectorAll('td');
  if (cells.length > 5) {
    tokens.push({
      rank: cells[1]?.innerText,
      name: cells[2]?.querySelector('a')?.innerText,
      price: cells[4]?.innerText,
      change_24h: cells[5]?.innerText,
      market_cap: cells[8]?.innerText
    });
  }
});
return tokens;
Step 3: Scrape CoinMarketCap

Navigate to CoinMarketCap:

bash
agent-browser open https://coinmarketcap.com/

Take snapshot:

bash
agent-browser snapshot -i

CoinMarketCap provides:

  • Similar data to CoinGecko
  • Fear & Greed Index
  • Trending tokens
  • Recently added tokens
Step 4: Extract Token Data (CMC)

Extract similar fields from CoinMarketCap table.

Note: CMC may have different CSS selectors. Use snapshot to identify correct refs.

Step 5: Extract Trending & New Tokens

Both platforms show trending/new tokens. Capture these separately:

CoinGecko Trending:

bash
agent-browser open https://www.coingecko.com/en/discover

CoinMarketCap Trending:

bash
agent-browser open https://coinmarketcap.com/trending-cryptocurrencies/

Extract:

  • Trending tokens (most searched/traded)
  • Recently added tokens
  • Top gainers/losers
Step 6: Compile Results

Merge and deduplicate data from both sources.

Output format (JSON):
