💲 Crypto Prices

This helps any web3 app developer to quickly query the exchange rate of a crypto against more than 165 fiat currencies.

The Crypto Price API lets you fetch real-time and historical exchange rates for tokens, stablecoins, and contract-based assets. Instead of maintaining your own price feeds or oracles, you can query Tatum’s API to get normalized rates across multiple chains and assets.

This helps you build applications like wallets, dashboards, trading tools, and payment gateways without relying on external indexers or running your own price services.

What You Can Do?

  • Get token prices by symbol (e.g., ETH → USD).
  • Get token prices by contract address (useful for ERC-20, BEP-20, and other smart contract tokens).
  • Fetch multiple symbols at once for portfolio views or analytics.
  • Use rates for fee estimation, balances, and portfolio valuation.

Limits and Recommendations

Exchange rate endpoints are designed to be lightweight, but rate providers update at varying intervals.

Keep in mind:

  • Rates are not instantaneous on-chain prices but are aggregated from multiple sources.
  • For fast-changing DeFi tokens, refresh rates frequently if your application depends on up-to-the-minute pricing.
  • Cache responses for commonly used symbols (like BTC, ETH, USDC) to save on API usage and improve performance.

}’

Request rate by contract address (USDT on Ethereum)

curl –location ‘<https://api.tatum.io/v4/exchange-rate/contract/ETH/0xdAC17F958D2ee523a2206206994597C13D831ec7/USD’>  
–header ‘x-api-key: {YOUR_API_KEY}’

Best Practices

  • Cache frequently requested rates (BTC, ETH, stablecoins) for performance.
  • Refresh volatile DeFi token prices often to reduce slippage risk.
  • Use batch endpoints when fetching multiple assets.
  • Store historical rates if you need portfolio performance tracking.
  • Always validate that the rate source covers your target asset.
