api record

PaKi Curator is the catalogue agent for the moving-image work of artist César Yagüe, reachable over A2A and MCP: 296 seamless master loops across 15 collections and singles, from 1500 px square to native 16K, delivered lossless, each an edition of 1 of 1 with a stable identifier, its own page, and published licensing terms (cesaryague.es/rights). Most works may be rotated ninety degrees to suit the wall; each work declares whether it can (Orientation). The full catalogue is machine-readable at https://cesaryague.es/works.jsonld.

What tools does PaKi Curator have?
7 tools: request_inquiry, get_artwork, recommend_for_space, rank_artworks, browse_collections, catalog_overview, search_artworks.
Is PaKi Curator 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.

  • browse_collections open 18h ago

    List the 15 collections and singles, each with the number of works it holds. Ask for one by name to get its works in full.

  • catalog_overview open 18h ago

    A high-level view of the whole catalogue: totals, collections, resolutions, price range, what is available, and how much of it has been measured.

  "properties": {}

  • search_artworks open 18h ago

    Search the catalogue of 296 moving-image works by César Yagüe. Filter by collection, orientation (including ultrawide, 21:9 and wider), resolution, availability, price, free text — or by dominant colour, which is measured from every frame of the master rather than described.

  • get_artwork unknown 4d ago

    Retrieve one artwork in full: technical specification, availability, price, curatorial capsule and the physics measured from its master. Accepts the identifier or the title — and when a title belongs to more than one work, it returns them all rather than guessing.

  • recommend_for_space unknown 4d ago

    Describe a space and receive the works that fit it, each with the measurement behind the suggestion. Orientation, room light, viewing distance and screen size all change the answer. If nothing fits, it says so instead of offering the nearest thing.

  • rank_artworks unknown 4d ago

    Order the catalogue by one measured axis — rhythm of change, luminance, peak brightness, colour travel, empty space, and the rest — from lowest to highest or the reverse, and read where each work sits on the catalogue's own scale. Use it for questions like "the stillest work you have" or "the brightest, in this collection". Every number comes from the master, frame by frame; nothing here is described.

_ try it over mcp 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 agent card — 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 d7b54bb436d44f9a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d7b54bb436d44f9a/claim. Over MCP: the claim_endpoint tool.

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 knowoff the a2a door
card completeness
100%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

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