🟢make_shape_collage(shape, photo_urls, photos, gap_pct, background)
Builds a photo collage in the shape of a heart, a number (age, anniversary, year), a word, a star, a flower and more from the user's photos, and returns a watermarked preview within seconds. Use when the user asks for a heart collage, a birthday/anniversary number collage, a 'photo collage in the shape of ...', or a collage from several photos. Pass the photos as public links in photo_urls, or as files the user attached (photos). 1 to 300 photos; if there are fewer photos than cells, photos repeat. The result id (clg_...) is a private handle valid for 30 days; photos and results are deleted after 30 days. The preview is watermarked; the full-resolution file is downloaded from the collager.ai page given in full_resolution_page. Building can take up to a minute - if status is still processing, call get_shape_collage with the id.

Input Schema
{
"type": "object",
"additionalProperties": false
}🟢list_mosaic_styles
Shows the looks of a Collager.ai photo mosaic (one large picture made of hundreds or thousands of small photos) with example images: soft classic, clean subject, stronger mosaic, uniform or mixed tile sizes. Use before start_photo_mosaic when the user wants to choose a style.
Input Schema
{
"type": "object",
"additionalProperties": false
}🟢start_photo_mosaic(occasion)
Gives the link where the user builds a photo mosaic: one main photo recreated from many small photos (best with 100-2000 photos - family archive, wedding, team, school year). The user uploads the photos on collager.ai, picks the style, and the site builds a watermarked preview in minutes. Use when the user wants a photo mosaic or a picture made of many photos.

{
"type": "object",
"properties": {
"occasion": {
"type": "string",
"maxLength": 60,
"description": "Optional: what it is for (anniversary, memorial, wedding, team ...), used only to tailor the tips."
