Getting Started

This API uses OAuth for authentication, which is more involved than a simple API key but provides better security, especially when accessing user data.

Register your app — Create an application on the API provider's developer portal to get a Client ID and Client Secret.
Implement the OAuth flow — Redirect users to the provider's authorization page, where they grant permission to your app.
Exchange the code — After authorization, you'll receive a code that you exchange for an access token.
Use the token — Include the access token in the Authorization header of your API requests.

OAuth is commonly used by APIs that access personal data (like social media accounts). Many libraries exist to simplify the OAuth flow in every major programming language.

CORS Support

CORS support for this API is unknown. If you get cross-origin errors in the browser, try calling the API from your server instead.

Quick Example

// Using cURL
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" https://docs.clarifai.com/api-guide/api-overview

// Using JavaScript fetch()
const response = await fetch(apiUrl, {
  headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
});
const data = await response.json();

Frequently Asked Questions

What AI capabilities does Clarifai offer?

Clarifai provides machine learning or AI functionality that you can integrate into your applications via API calls. This might include text analysis, image recognition, natural language processing, predictions, or other intelligent features. Check the documentation for the specific models and capabilities available.

Do I need ML expertise to use Clarifai?

Most AI and ML APIs like Clarifai are designed to be accessible to developers without deep machine learning knowledge. You send data to the API and receive predictions or analysis back — no need to train models yourself. The API handles the complex ML infrastructure behind the scenes.

What are the rate limits and processing times for Clarifai?

AI APIs often have stricter rate limits than simpler data APIs because each request requires significant computation. Processing time varies based on the complexity of the task (e.g., image analysis takes longer than text classification). Check Clarifai's documentation for specific rate limits and expected response times. Browse more Machine Learning APIs for alternatives.

Is Clarifai free to use?

Yes, Clarifai is listed as a free public API. You will need to register an application to get OAuth credentials, but access is free. Some APIs have rate limits on their free tier, so check the official documentation for current limits.

Is Clarifai still working in 2026?

Yes! According to our most recent health check (Clarifai's last ping: 2026-04-01 13:44:24), this API is responding normally. We periodically verify all listed APIs to ensure they are still online and functioning.
