Visit the Meta developer platform and create the account or team needed to access Model API. Review public-preview availability for your location and generate an API key through the documented setup. Select a supported model and inspect its pricing, limits, and data-use conditions. Keep the key on your server, then follow the current quickstart to make a small test request. Configure the compatible SDK or protocol according to the model you choose. Add grounding tools only when the request and model support them. Validate returned content and handle rate limits before connecting the endpoint to real users. Monitor your team’s usage and charges in the developer interface. Recheck preview documentation during upgrades, since supported models and service conditions can change.
