Errors | Simplified Developer Docs

Status	Meaning	What to do
`202`	Accepted; work continues in the background	Poll — see Async jobs
`400`	Validation failed	Read `detail`; check required fields
`401`	Missing or invalid credential	Check the header carries an `Api-Key` or `Bearer` prefix
`403`	Authenticated, but no access to this workspace or space	Check key scoping
`404`	Not found, or outside your workspace	Cross-tenant resources return 404 by design
`429`	Out of credits, or rate limited	Check credits; back off and retry

Validation errors return field-keyed detail:

{
  "model": ["This field is required."],
  "parameters": ["This field is required."]
}

For image and video generation, model-specific settings belong nested under parameters, not flat on the request body. Unknown keys are dropped rather than rejected, so a misplaced setting produces an unexpected result instead of an error.
