Omni-moderation model always returning 429 even on first request

Trying to use the OpenAI omni-moderation model for my project but every request returns 429 Too Many Requests. Even tested it in Postman with a fresh API key and the very first request still failed with 429. Not sending high traffic or anything, so I’m confused what’s causing it. { “error”: { “message”: “Too Many Requests”, “type”: “invalid_request_error”, “param”: null, “code”: null } }
