Why am I getting an error code when I try to retrieve my data acquired via API?

When acquiring data via API, it is possible that when you call an API, it may not be available for several reasons.

Here are the Data Exchange Solution (DXS) error codes that may be reported to a data acquirer and their meanings:

Codes	Descriptions
400	The request does not match the description in the data offering For example, a required parameter is missing
401	The API key is unknown or cannot be found
403	The API key is recognized but is not authorized to access this data offering
404	The URLbase is incorrect or the route cannot be found in the specification
429	For quota-based transactions, too many requests have been made For unit-based transactions, the number of units has been exhausted For volume-based transactions, the number of requests has been exhausted
500	Internal error
502	Error when the DXS cannot contact the data provider's API (several possible technical causes)

These are DXS error codes only.

If the error originates from the data provider, DXS returns the error returned by the data provider's API.
