paneui.com

Hand the human a rich interactive UI by URL and (optionally) get structured data back.

Fetch a pane's current metadata (status, title, template version, timestamps, expires_at) WITHOUT its event log.

Poll a pane's append-only event log for what the human did (form submissions, approvals, picks).

Push an event INTO an open pane — update the live UI the human is looking at (progress, a new message, a status change, fresh data).

Edit instance-level fields on a LIVE pane in place (PATCH) without minting a new one — the pane keeps its id, URL, event log, and template pin.

Re-pin a LIVE pane to swap its HTML (design) + event/input/record schemas in place — same URL, no new pane.

Enumerate YOUR agent's panes (newest first).

Close/delete a pane (idempotent — an already-closed pane still succeeds).

List rows in a pane's mutable record collection (todo list, shopping list, kanban board, comment thread).

Fetch a single record row by its key from a pane collection (scans the collection — fine for a one-off lookup, not a hot loop).

Create a row in a pane's record collection, or return the existing row if record_key is already present (deduped:true).

Update an existing row in a pane's record collection (replaces its data).

Soft-delete a row from a pane's record collection.

Drop a WHOLE per-pane record collection at once: every row plus the collection row itself.

Manage reusable, versioned UI templates (author once, instance many times via create_pane's template_id).

CRUD for TEMPLATE-level record collections — owner-curated content anchored to a template head and visible to every pane derived from any of its versions (vs per-pane records, which are the discrete record tools).

Manage a pane's participant URLs (recovery + leak-containment).

Identity sharing on a pane (layered on top of participant tokens).

Binary attachments (images, PDFs, audio, video) referenced from event payloads / input_data via `format: pane-attachment-id`.

Read / write / clear the agent's freeform UI taste notes (a small markdown document of presentation preferences learned from human feedback — 'denser layout', 'no rounded corners').

Inspect or revoke the calling agent's API key.

Manage soft-deleted panes + templates.

Send or list feedback to the relay operator.

Agent identity + binding.

Run read-only SQL over YOUR scoped data (panes, records, events) — the relay scopes every row to panes you own.

Fetch the relay's auto-updating SKILL.md (the full Pane usage guide) — UNAUTHENTICATED, needs no API key.
