MemeStack

Search the MemeStack image gallery. Runs semantic AI and keyword matching in parallel and merges results. Returns images with captions, tags, zap stats, and URLs.

Get full metadata for a specific image by ID, including caption, alt text, tags, OCR text, zap stats, and URLs.

Find visually similar images using perceptual hash matching. Returns images that look alike.

Find semantically related images using AI embedding similarity. Returns images with similar meaning/topic.

Browse and filter the image gallery without a search query. Useful for discovering content by tag, trending, or recent uploads.

Get a user's public profile including display name, stats, and avatar info.

Get top-ranked images by zaps received, or top zappers by amount zapped, over a time period.

Browse images for a specific tag. Returns the tag profile (description, stats) and optionally a paginated list of images tagged with it.

Get a category and its featured images. Categories group related tags (e.g. "charts", "memes", "lightning-network").

List all available image categories. Use this to discover what categories exist before calling browse_by_category.
