Vero Data Hub API

Quick checklist

Check method and path

Compare your request against the endpoint page in the API reference.

Check credentials

For 401, verify the API key assigned to your account.

Check time format

Use ISO 8601 UTC timestamps with a Z suffix for from and to.

Check response status

Use the response tabs in the playground to inspect each status code.

Symptom	Common cause	Fix
`400 Invalid query parameter`	Missing required parameter or invalid time format	Check required params and use UTC `Z` timestamps
`401 Unauthorized`	Missing or invalid credential	Check your API key
`404 Not found`	Symbol, fund code, report ID or news ID does not exist	Use a list endpoint to find the correct value
`422 Unprocessable`	Correct format but unsupported value	Check enum values such as resolution or statement type
`429 Too many requests`	Request limit exceeded	Reduce request rate and retry later
`503 Unavailable`	API temporarily unavailable	Retry with backoff
