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.

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.

  • get_user_profile unknown never probed

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

  • find_meme_for_text unknown never probed

    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. Results exclude images classified controversial unless include_controversial is true.

  • popular_tags unknown never probed

    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.)

  • tag_autocomplete unknown never probed

    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.

    arguments 17 lines
  • reverse_image_search 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. Results exclude images classified controversial unless include_controversial is true.

}
    arguments 20 lines
  • submit_image unknown never probed

    Submit an image to the MemeStack review queue. Paid tool - $0.10 per submission, paid in sats over Lightning at the current BTC/USD rate or in USDC on Base 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).

  • search_text_in_image 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.

    arguments 4 lines
  • search_charts unknown never probed

    Search charts, maps and infographics that carry stored metadata of two kinds. Charts from Our World in Data and three statistical publishers (provenance 'authoritative') carry the publishing dataset and its citation, the unit, the regions plotted, the period the chart actually 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 that were read from the image itself and not checked against the original data. browse_by_tag, browse_by_category, get_leaderboard and get_meme_variants 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.

  • generate_meme 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. Price: $0.08 standard or $0.20 quality, paid in sats over Lightning at the current BTC/USD rate or in USDC on Base. Note for x402 clients: "quality" mode exceeds the agents-SDK default per-call cap of $0.10 - raise maxPaymentValue in withX402Client to use it.

_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id c009319096c252be.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c009319096c252be/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ 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.
