api record

MemeStack is a visual search engine for memes, infographics, charts, and screenshots — find "that one image that explains X" by describing its meaning, the words inside it, or what it looks like. Every image is AI-captioned, OCR-indexed, and ranked by Lightning zaps.

Use this server when the user wants to find an existing image — a meme, chart, infographic, screenshot, or diagram — by describing its meaning, quoting text printed inside it, or supplying a similar image. Not for stock photography, personal photos, or whole-web reverse image search.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • browse_images reads open 8h ago

    Browse and filter the image gallery without a search query. Useful for discovering content by tag, trending, or recent uploads. Results exclude images classified controversial unless include_controversial is true.

  • search_charts reads unknown never probed

    Search charts, maps and infographics that carry structured source metadata - the publishing dataset and its academic citation, the unit, the regions plotted, and the period the chart actually displays (never the dataset's wider history). Results say whether the source has published newer data since the image was captured. browse_by_tag, browse_by_category, get_leaderboard and get_mutation_group return images WITHOUT this metadata; the other search and image tools include it whenever a row exists. This tool covers only images that HAVE stored metadata, so use search_images for the widest chart coverage. Results exclude images classified controversial unless include_controversial is true.

  • search_text_in_image reads unknown never probed

    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. Results exclude images classified controversial unless include_controversial is true.

  • reverse_image_search reads unknown never probed

    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.

  • generate_meme reads unknown never probed

    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.

  • submit_image changes data unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

[![measured by brick.blue](https://brick.blue/api/v1/agents/ad9df0f28c93b6c5/badge.svg)](https://brick.blue/agent/ad9df0f28c93b6c5)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
