View on GitHub → Complete crypto market data for autonomous agents. One AISA_API_KEY unlocks CoinGecko — prices, charts, OHLC candles, on-chain token lookup, exchange tickers, trending coins, and news. Everything an agent needs to research, screen, and track the crypto market.

Install

aisa skills install crypto-market-data

​
What can agents do with it?

Price tracking

“Get current BTC and ETH prices in USD and EUR with 24-hour change.”

Historical charts

“Pull bitcoin’s 30-day price chart in USD for my dashboard.”

OHLC candles

“Return the last 7 days of OHLC candles for ethereum.”

On-chain token lookup

“Identify the ERC-20 at address 0xA0b8…eB48 and pull its price.”

Market-cap screening

“Show me the top 25 coins by market cap, ordered descending.”

Exchange research

“List Binance tickers ordered by trust score.”

​
Core capabilities

  • Simple prices — current prices across fiat and crypto currencies, with optional market-cap / 24h-volume / 24h-change includes
  • Coin data — full coin profile, lists, historical snapshots, market charts, OHLC candles, tickers
  • Contract-based lookup — resolve a token by contract address on a supported platform (Ethereum, BSC, Polygon, etc.) and pull its price or full profile
  • Markets & screening — coins by market cap with flexible ordering and pagination
  • Categories — category lists and per-category market leaderboards (DeFi, AI, L1s, etc.)
  • Exchanges — exchange lists, detailed data, trading pairs, ID mappings
  • Trending & news — trending search queries and current crypto news
