How-To Resolve '403 Forbidden' Returned by Crusoe Managed Inference

Last Updated: Mar 23, 2026

Introduction

Sending requests to the Crusoe Managed Inference service returns the following error: 403 Forbidden.

This article provides steps to troubleshoot and resolve the error.

Prerequisites

• Crusoe Account: Access to the Intelligence Foundry enabled.
• Crusoe Managed Inference API key

Step-by-Step Instructions

The most common reasons for 403 Forbidden errors are:

1. Incorrect API key:
   Make sure you copied the Crusoe Managed Inference API key correctly. Also, double check the expiration date and confirm it's still valid.
2. Quote Formatting:
   If you're using double quotes (") to encapsulate your API key in the curl request, change it with single quotes ('). Double quotes can lead to parsing errors because they allow the terminal to interpret special characters like $ inside the key.

If the above doesn't resolve the errors, please Submit a Support Request.
