Create an account in the API console and generate a key for the project you are building. Store the key as a server-side secret and follow the current SDK quickstart or REST reference. Select a supported Grok model and send a small request that reflects your application’s real inputs. Add instructions and tools gradually, testing how the model behaves when required information is missing. Validate the returned content before using it in automated workflows, and provide a useful fallback for errors or quota limits. Inspect token usage and any additional tool or media charges in the console. Keep keys out of client bundles and public repositories. Check the current model catalogue and pricing when deploying, since consumer Grok access and API billing are separate products.
