Any other status: an error

A status of 400 or above answers with the error object. Branch on its code, never on its message.

Errors

Beside the errors every call can answer with (a bad key, a missing scope, the rate limit), this call answers with:

Errors of List conversion offers
Code	HTTP	Meaning
`asset_unsupported`	400	Not an asset id from `GET /v1/assets`, or not usable for this purpose.
`insufficient_balance`	409	The available balance (amount minus reserved) of the source asset is too low; `error.available` gives it.
