Test your actual images
Include people, fine hair, reflective objects, white products, and low contrast scenes if they appear in your workload. Compare edge quality at the final display size, not just a small preview.
Read the full contract
Check authentication, accepted formats, maximum input size, output choices, rate and concurrency limits, error responses, and billing rules. A similar-looking endpoint does not mean every parameter or client is compatible.
Review data handling and operations
Understand where images are processed, retention behavior, service dependencies, and available support. Start with a measured pilot and keep a fallback plan for failures or quality issues.
