chord_find_token

Find a token by symbol, name or address on a chain Chord trades on (base, ethereum, monad, bnb, avalanche, arbitrum, robinhood, arc). Returns addresses, decimals and whether the token is verified; similar tickers are common, so compare addresses.

chainstring, required

Chord chain key.

querystring, required

Symbol, name or 0x address.

chord_find_token

read-only

Argument	Type	Description
chain*	string	Chord chain key.

chord_swap_quote

Best swap route from Chord (getchord.xyz) across the DEXs of the chain, with the UNSIGNED transaction to sign, the ERC-20 approval it needs (as a ready transaction) and a simulation run from the taker wallet. Amounts are integer strings in the token's smallest unit; the zero address is the native coin. Nothing is sent: sign with your own key, then send_raw_transaction.

read-only

Argument	Type	Description
chain*	string	Chord chain key.
taker	string	The wallet that will sign. With it the answer carries tx + approval + a simulation from that wallet.
amount*	string	Amount of tokenIn in its smallest unit, e.g. '10000000' = 10 USDC.
tokenIn*	string	Token sold (zero address = native coin).
tokenOut*	string	Token bought (zero address = native coin).
slippageBps	integer	Slippage in basis points (default 50).
