Handling Unrecognized Inputs in Image Profile API Workflows

When integrating computer vision tools into your application, the most robust workflows account for the reality that not every input will be a perfect, high-resolution portrait. Whether due to broken links, corrupted files, or non-human subjects, your application needs a strategy to handle inputs that the API cannot process.

Understanding the Recognition Lifecycle

The Image Profile API (/v1/image/profile) operates by analyzing an image source—either a public URL or a base64-encoded string—and returning attributes like estimated age, gender, and category.

Crucially, the API distinguishes between a successful recognition and a non-billable state. Understanding this distinction allows you to build resilient integration boundaries that don't penalize your usage metrics for malformed or unreachable inputs.

Step 1: Secure Your Credentials

Before making requests, ensure your X-API-Key is handled securely. Never hardcode your key in your source code. Use environment variables or a secret management service to inject the key at runtime.

# Example: Setting your key as an environment variable
export EKYC_API_KEY='your_secret_key_here'

Step 2: Implement the Integration Boundary

When you send a request to the /v1/image/profile endpoint, your logic should check the success boolean before attempting to process the returned data.

If the API cannot recognize the image (e.g., a 404 on an image URL or an unreadable binary), it returns a success: false response. According to the API documentation, these specific instances are marked with pricingStrategy: FREE and do not incur billing costs.

Conceptual Implementation Pattern

// Conceptual logic for handling API response
async function processImage(inputData) {
 const response = await fetch('https://api.ekycpro.com/v1/image/profile', {
 method: 'POST',
 headers: { 'X-API-Key': process.env.EKYC_API_KEY },
 body: JSON.stringify(inputData)
 });

 const result = await response.json();

 if (result.success === false) {
 // Handle non-billable, unrecognized input
 console.log('Image could not be recognized; no charge applied.');
 return null;
 }

 // Proceed with processing successful attributes
 return result.data;
}

Step 3: Handling HTTP Status Codes

Beyond the success field, your error handling should account for standard HTTP status codes:

• 400: Check that you are providing exactly one of image_url or image_b64 and that your base64 string is properly formatted.
• 401: Ensure your X-API-Key is correctly passed in the headers.
• 500: Indicates a server-side issue; implement a standard retry policy for these cases.

Conclusion

By checking the success flag and pricingStrategy before proceeding, you can create a clean separation between valid user profiles and unrecognized noise. This approach ensures your application remains stable when dealing with unpredictable user-provided images while maintaining clear visibility into your integration’s health.
