Tools & batch

Data charts, stateless re-generation, multi-slide carousels, animated GIFs, bulk generation, and pattern discovery — full parity with everything the Studio web app can do.

Example KPI chart with three metric tiles — A /chart response — chartType: "kpi", generated deterministically from the data in this page’s code sample.

POST/api/v1/renderFree

content	Required	The content object from a prior response, optionally edited.
size	String	Override the canvas aspect ratio.
theme	String	Override the color mode.
brand	Object	Override branding for this re-render only.

POST/api/v1/animateIncluded · Developer plan

Turns content you already hold — or an existing diagram — into a reveal GIF. Offloads to an async job (poll GET /api/v1/jobs/{id}) for larger renders; otherwise generates inline and returns the GIF directly. Two input modes, pick one.

Can take up to a couple of minutes for large animations — build your integration around the async jobId path, not just the inline one.

Field	Type	Description & options
format	String	Which pattern this content belongs to. Required together with content; omit when using diagramId.
content	Object	The content object to animate. Required together with format; omit when using diagramId.
diagramId	String	Animate an existing diagram from /api/v1/diagrams instead of raw content. Cannot be combined with format/content.
anim	String	Animation style — flow reveals along the connections/edges, build reveals elements in sequence. `flow (default)build`
speed	String	Playback speed. `slownormal (default)fast`
size	String	Override the canvas aspect ratio.
brand	Object	Per-request branding override (ignored when animating an existing diagramId — it keeps its own saved brand).

# Mode 1 — animate content you already hold (from a prior /posts or /chart call)
curl -X POST https://api.capci.app/api/v1/animate \
  -H "x-api-key: capci_your_api_key" -H "Content-Type: application/json" \

# → { "async": true, "jobId": "…" }  when offloaded — poll GET /api/v1/jobs/{jobId}
# → { "gif": "data:image/gif;base64,…" }  when generated inline (small/fast payloads)

# Mode 2 — animate an existing diagram by id instead (mutually exclusive with format/content)

base	Object	Fields shared by every item.
items	Required	Array of per-item overrides merged onto base, up to 200.
theme	String	Color mode, applied to every item. `light (default)dark`

GET/api/v1/jobs/{id} · /api/v1/jobs/batch/{batchId}Free · unlimited polling

Poll status for an async job created by /animate or /batch. Returns { status: 'queued' | 'rendering' | 'done' | 'failed' } while pending, plus the image(s) once done. Not subject to the 20/min generation rate limit — poll every 2-3s.

Lists every post format id with its human-readable title and the exact content schema it expects — the machine-readable counterpart to the format pills on the Posts page. Useful if you're building your own prompt/format picker UI against this API.
