api record

Renderball turns a deck you write into a designed, animated, editable presentation the user can finish in the Renderball editor and share. Write it the way the studio's own writer does, ONE PAGE AT A TIME: (1) create_deck with the user's brief, the brand (if you can open the brand's website, read its real colours and fonts there and declare them; always give the website; never invent a colour) AND your outline, one entry per page — the reply carries PAGE 1'S BRIEF with example pages chosen for it. (2) Study the examples, follow THE STUDIO'S METHOD, write page 1 (the file with Section0 and the…

_ is it live, free and safe measured by this hub
Is renderball live?
Yes — it answered the hub's last check (checked 47m ago). It answered 100% of checks over the last 30 days.
Is renderball free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does renderball have?
13 tools: deck_status, read_page, get_page_brief, get_examples, create_deck, get_brief, write_outline, see_deck, ….
Is renderball safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

  • list_decks reads auth-required 5h ago

    The user's Renderball documents, newest first, with editor links. Needs an account (a key). The design open in the person's editor right now comes first, marked open_now.

  • read_page unknown 5h ago

    Read one page of a design as it is NOW — the code the person's editor shows, including their own edits — before changing it. Use it whenever the person asks to change something in a design that already exists: their editor may hold edits you have not seen. The reply carries the page's code, the code every page shares (palette, fonts, helpers), the page's element ids and, when the person has the design open, the element they selected ("this").

    The full writing brief for ONE page: the studio's method, the rules, the examples chosen for that page, and (after page 1) page 1's file to continue. You rarely need it: page 1's brief comes with create_deck and each submit_page reply carries the next page's. Use it for a helper that writes one page with nothing in front of it.

  • create_deck changes data unknown never probed

    Start a new presentation from a brief, the brand and your outline. The brand: if you can open the brand's website, read its real colours and fonts there first and declare them — the lead colour is usually the main buttons and the large coloured areas, not the link colour — and always give the website; never invent a colour. With the outline the reply carries PAGE 1'S BRIEF; write page 1 and send it with submit_page — each reply carries the next page's brief.

  • see_deck reads unknown 23h ago

    The deck's rendered pages as images, page 1 first — look at them for overlapping or clipped text, odd spacing, an element off its page or a picture that does not say its page's claim, then fix that page and submit_page it again. Available once the deck has been rendered.

  • edit_page unknown never probed

    Change part of a design that already exists, the way you edit a file: each edit replaces exact text from read_page (it must appear exactly once) with new text. Use it for any change the person asks for in an existing design — a headline, a colour, a picture, moving or removing something — instead of sending the whole page again: everything you do not touch stays as it is, the person's own edits included, and they see the change in their editor at once and can undo it. One page per call, or shared: true for the code every page shares. A refused edit changes nothing and says why. The reply shows the page as it looks now.

  • submit_deck changes data unknown never probed

    Replace the whole file of a deck whose pages are all written (while pages are still being written, submit_page each one — a whole file is refused then). Renderball checks it against the brief, renders every page and opens it in the editor. Returns 'ready' with the editor_url, or 'importing' — then poll deck_status.

  • submit_page unknown never probed

    Save one page you wrote (page 1: the file with Section0 and the shared design; page N: only its Section), with its direction (one sentence: the thing, the motion that acts out the claim, one craft detail). A page is accepted only after its brief was handed to you. The reply carries the next page's brief; when every page is saved the deck is merged, checked and rendered and the reply carries the rendered pages. To rewrite one page of a finished design, submit just that page: it replaces that page only, and everything else stays as it is, the person's own edits included. To change part of a page, read_page and edit_page are lighter.

_ 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 ab943d0d1f893c67.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ab943d0d1f893c67/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/ab943d0d1f893c67/badge.svg)](https://brick.blue/agent/ab943d0d1f893c67?ref=badge)

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.
