MemeStack

Get a tag's profile (description, image count, related tags) without fetching any images. Use browse_by_tag to also retrieve images.

Get a MemeStack uploader's public profile: display name, stats and avatar.

List the image categories (e.g. charts, memes) with their descriptions and image counts. Use it before calling browse_by_category.

List the most-used tags (topics) on MemeStack by all-time usage count. (Time-period filtering is not yet supported - tag usage is currently counted across the full lifetime of each tag.)

Find a meme, chart or screenshot on MemeStack from a copy of the image - to name a meme or find where an image came from: give an HTTPS image URL, or a `data:image/...;base64,...` URL for bytes pasted into the conversation, and get the same or visually similar images with their source and citation. Matches by perceptual hash (dHash hamming distance), so it finds copies and edits, not images about the same topic. Heavily rate-limited (10/min/IP) since each call hashes the input.

Search charts, graphs, maps and infographics with their source data: the dataset and its citation, the unit, the regions plotted and the period the chart actually shows. Two kinds of stored metadata: charts from Our World in Data and three statistical publishers (provenance 'authoritative') carry the publishing dataset and its citation, the period the chart displays (never the dataset's wider history), and whether the source has published newer data since the image was captured; community-uploaded charts (provenance 'extracted') carry a title, source line, unit and period read from the image itself and not checked against the original data. This tool covers only images that HAVE stored metadata, so use search_images for the widest chart coverage; search_images, get_image and cite_image carry the same metadata whenever a row exists. Set publisher_only to keep only the publishers' own charts (licence-clean, citable). Every image carries rights (source publisher/creator/community, licence, attribution line, commercial_use yes/no/unknown - unknown is never a guess), and match_quality says whether the search found any strong match (strong / closest_only / none). When corrected_query is present, the results are for that corrected wording, not the words as typed - say so to the user.

Search memes, reaction images, charts, graphs, infographics and screenshots by meaning or keywords - the general image search. Semantic and keyword matching run together and merge. Returns each image with its caption, tags, image and page URLs and a ready citation (source, licence). Use the key words only: a long descriptive phrase matches fewer images strongly. Every image carries rights (source publisher/creator/community, licence, attribution line, commercial_use yes/no/unknown - unknown is never a guess), and match_quality says whether the search found any strong match (strong / closest_only / none). When corrected_query is present, the results are for that corrected wording, not the words as typed - say so to the user.

Find screenshots, memes and other images by the exact words printed in them (OCR text): a quote, a caption, a sign, a watermark. Matches only the text in the image (the text_in_image field), not captions or tags, and returns strong matches only, each with a ready citation.

Suggest tag slugs matching a prefix. Use this to verify a tag exists before filtering by it, or to discover related tags. Prefix must be >= 2 characters.
