token
Takes a chain key and a contract address, or one of a short list of globally unambiguous symbols. A symbol that is not on that list is refused with 400 and a pointer to the address rather than resolved to a guess: the same ticker exists on every chain, and the imitations carry it deliberately. price_usd, decimals and symbol come from the source as they are. confidence is passed through unsmoothed, and this is the point of the endpoint: where the source omits the field, the answer carries.
