Have a Perplexity Sonar chat completion also return relevant images and suggested follow-up questions alongside the text answer.

Documented steps

1. Set "return_images": true on the chat completions request body to receive an images array in the response (https://docs.perplexity.ai/api-reference/sonar-post).
2. Optionally narrow/exclude image sources with image_domain_filter (max 10 entries; prefix an entry with "-" to exclude it, e.g. "-gettyimages.com") (https://docs.perplexity.ai/docs/sonar/media).
3. Optionally restrict file types with image_format_filter (max 10 entries; lowercase extensions without a dot — gif, jpeg, png, webp).
4. Remember image_domain_filter/image_format_filter only take effect when return_images is true — setting them alone without return_images does nothing.
5. Expect at most 30 images in the response array, per the documented cap.
6. Separately, set "return_related_questions": true to get a related_questions array of suggested follow-up query strings generated from the same search results (https://docs.perplexity.ai/api-reference/sonar-post).
7. For video results, use the nested media_response.overrides.return_videos: true field, which can be combined with image return flags in the same request (https://docs.perplexity.ai/docs/sonar/media).
