Errors

404: Not Found
- You have requested a URL that does not match any of the endpoints.

400: Bad Request
- You have requested a URL that includes a YYYY-MM-DD formatted date and the input is not a valid date (ex: 2023-30-01 — there is no 30th month, 2023-02-29 — there is the 29th of February in 2023)

Errors as a response header and json parameter
- If a parameter input was not within the list of allowed values, or the parameter was not within the list of expected parameters, this will appear within the response header ‘X-Error’ as well as within the json response body under the key ‘error’. A response is still given with the data that was most likely intended to be queried.
