What this server can do
20 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
browse_by_category(category)- Get a category and its featured images. Categories group related tags (e.g. "charts", "memes", "lightning-network"). Required: category.
browse_by_tag(tag, limit, offset)- Browse images for a specific tag. Returns the tag profile (description, stats) and optionally a paginated list of images tagged with it. Required: tag.
browse_images(tag, sort, limit, offset)- Browse and filter the image gallery without a search query. Useful for discovering content by tag, trending, or recent uploads.
cite_image(image_ids)- Generate canonical attribution blocks for one or more MemeStack images. Returns markdown, HTML, and plain-text citation strings ready to paste into your output, plus a combined block for citing multiple images at once. Required: image_ids.
find_meme_for_text(vibe, limit)- Find a meme that captures a vibe, idea, or concept. Returns ready-to-embed images with citation blocks. Use this when writing posts, articles, or social content and you need a meme to illustrate a point. Required: vibe.
find_related(id, limit)- Find semantically related images using AI embedding similarity. Returns images with similar meaning/topic. Required: id.
find_similar(id, limit)- Find visually similar images using perceptual hash matching. Returns images that look alike. Required: id.
generate_meme(mode, prompt, aspect_ratio)- Generate a new image from a text prompt using AI (Grok Imagine). Paid tool — billed per call via the agent payment rails (x402/L402); not covered by any free quota. Generation runs asynchronously on the server and this call polls until it completes, up to ~90 seconds. If you get a "still running" error, call the tool again with the SAME payment proof to resume polling — you will never be charged twice for one payment. Note for x402 clients: "quality" mode (~$0.15) exceeds the agents-SDK default per-call cap of $0.10 — raise maxPaymentValue in withX402Client to use it. Required: prompt.
get_image(id)- Get full metadata for a specific image by ID, including caption, alt text, tags, OCR text, zap stats, and URLs. Required: id.
get_leaderboard(type, period)- Get top-ranked images by zaps received, or top zappers by amount zapped, over a time period. Required: type.
get_mutation_group(image_id)- Get all variants of a meme template tracked on MemeStack. Returns the dominant image plus every variant in the same mutation group, with citation blocks for each. Use this to research how a meme has evolved or to find variants of a known image. Required: image_id.
get_tag_profile(tag)- Get the profile for a tag (description, image count, total zaps, related tags) without fetching any images. Use browse_by_tag to also retrieve images. Required: tag.
get_user_profile(identifier)- Get a user's public profile including display name, stats, and avatar info. Required: identifier.
list_categories- List all available image categories. Use this to discover what categories exist before calling browse_by_category.
popular_tags(limit)- List the most-used tags 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.)
reverse_image_search(url, limit)- Find MemeStack images that look visually similar to a given image. Accepts an HTTPS image URL or a `data:image/...;base64,...` URL for bytes pasted into agent context. Returns visually-similar matches via perceptual-hash (dHash) hamming distance, with citation blocks. Heavily rate-limited (10/min/IP) since each call hashes the input. Required: url.
search_images(q, tag, sort, tags, limit, query, offset)- 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. Required: query.
search_text_in_image(limit, query, offset)- Search for images by the text written or printed in them (OCR). Different from regular search — only matches the text_in_image field, not captions or tags. Use this to find screenshots of specific quotes, signs, watermarks, or memes with specific embedded text. Required: query.
submit_image(tags, caption, image_url, attribution)- Submit an image to the MemeStack review queue. Paid tool — 100 sats (or USDC equivalent) per submission via the agent payment rails (x402/L402); no account or API key. IMPORTANT: there is NO refund if moderation rejects the submission (duplicate, nsfw/spam, low quality) — the fee is the anti-spam mechanism. Accepted images await human review before publication. Accepts an HTTPS image URL or a data:image/...;base64 URL (JPEG/PNG/WebP, max 8MB). Optional caption/tags/attribution are hints shown to the AI tagger and moderators — never published verbatim. If the call fails or times out, retry with the SAME payment proof to resume — one payment delivers at most one submission and is never charged twice (up to 10 delivery attempts per payment; a corrected image_url is allowed while no submission has been created yet). Note for x402 clients: 100 sats exceeds the agents-SDK default per-call cap of $0.10 whenever BTC trades above $100k — raise maxPaymentValue in withX402Client if payment is refused client-side. Required: image_url.
tag_autocomplete(limit, prefix)- 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. Required: prefix.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
