Errors

Responses use a consistent body:

{
  "name": "unauthorized",
  "message": "Invalid API token",
  "statusCode": 401
}

`name`	Typical status	When
`validation_error`	422	Bad body, unverified from, suppression hit, etc.
`unauthorized`	401	Missing/invalid token or session
`not_found`	404	Unknown resource
`conflict`	409	Idempotency conflict, duplicate domain
`rate_limited`	429	Quota / rate limit
`internal_error`	500	Unexpected failure (no provider leak)

The SDK throws EvreApiError with code and statusCode matching name and HTTP status.
