Command line interface#
uniswap-python provides a basic command line interface named unipy, to let you easier query the chain for things like the current price and token metadata.
Example usage#
Note: uniswap-python contains a small database of token contract addresses for convenience. You can always provide a contract address in place of a shorthand, and need to do so for all tokens not in the bundled database, or if you’re not on mainnet.
# Get price for 1 WETH quoted in DAI $ unipy price WETH DAI 3350.883387688622 # Get price for 1 WETH quoted in DAI, skip decimal normalization $ unipy price --raw WETH DAI 3350883387688622003541 # Get price for 1 WETH quoted in USDT $ unipy price WETH 0xdac17f958d2ee523a2206206994597c13d831ec7 3348.128969 # Get token metadata from its ERC20 contract $ unipy token 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 {'name': 'Wrapped Ether', 'symbol': 'WETH', 'decimals': 18} # List known/hardcoded tokens, with metadata $ unipy tokendb --metadata {'name': 'Wrapped Ether', 'symbol': 'WETH', 'decimals': 18} {'name': 'Dai Stablecoin', 'symbol': 'DAI', 'decimals': 18} {'name': 'Wrapped BTC', 'symbol': 'WBTC', 'decimals': 8} ...
