Parameters
Parameter	Description
`chain` path · string · required	The chain the token lives on. Every chain is served, ARC included — ARC straight from the contract, and it 400s only while this deployment has no RPC URL for it. Which source answers is an internal decision and is not part of this contract. CELO, ARB, OP and SCROLL return 400 here.
`mint` path · string · required	The token mint address (Solana) or contract address (EVM).

A JSON response. Every field is always present; null means the value could not be established, never zero.
