Do I need a Pro plan for the API?

Yes. API access is included in the Pro plan (€5.90/month or €59/year). The free tier does not include API access.

How do I get an API key?

In your AnnexShow profile under Settings → API Tokens, generate a token starting with ask_.

What data does POST /api/v1/agent/visualize accept?

Either a list of nodes and edges, a chart object, objects3d for 3D primitives, or a text brief.

Text & JSON become diagrams, slides, and brand assets — via REST and MCP API.

Your agent supplies the data. AnnexShow turns it into a professional visualization in seconds and returns a shareable link. No design software, no manual layout work.

Why AnnexShow for agents

One API call, one finished visual.

Send a title, bullet points, or a JSON structure to the agent API. AnnexShow handles layout, colors, and aspect ratio. The result is ready to use immediately.

Every asset looks like it came from one source.

Brandkits store colors, fonts, and logos. Just pass a brandkit_id — AnnexShow applies your brand automatically to every generated graphic.

No file chaos, no version conflicts.

Every visualization can be published via a share link. The link works in browsers, emails, chat threads, or embedded in dashboards.

Same editor, two modes.

Use the visual canvas editor for manual work — or automate recurring graphics via the API. Perfect for AI agents, no-code workflows, and productivity tools.

Your data stays in the EU.

AnnexShow runs GDPR-ready on EU hosting — no US cloud lock-in.

3D on demand.

With "style": "3d" bar charts become isometric 3D visuals; objects3d places 3D primitives — editable like any other object.

What you can automate with the agent API

Use case	Input	Output
Synergy diagrams	List of terms or JSON nodes	Radial bubble diagram + share link
Org charts	JSON hierarchy	Tree diagram with reporting lines
Presentations	Slides with titles and bullets	Multi-page canvas presentation
Brand assets	Brandkit ID + content	On-brand graphic on the first try
Charts & KPIs	JSON data (labels, values)	Bar, line, pie, or 3D chart

Code examples

cURL — structure to share link

curl -X POST https://annexshow.com/api/v1/agent/visualize \
  -H "X-AnnexShow-Api-Key: ask_your_token" \
  -H "Content-Type: application/json" \
  -d '{
    "nodes": [
      {"id": "idea", "label": "Idea"},
      {"id": "concept", "label": "Concept"},
      {"id": "design", "label": "Design"},
      {"id": "launch", "label": "Launch"}
    ],
    "edges": [
      {"from": "idea", "to": "concept"},
      {"from": "concept", "to": "design"},
      {"from": "design", "to": "launch"}
    ],
    "layout": "tree",
    "title": "Process Flow",

Python SDK — diagram from JSON data

from annexshow import AnnexShow

client = AnnexShow(api_key="ask_your_token")

result = client.visualize(
    title="Quarterly Numbers",
    layout="radial",
    nodes=[
        {"id": "revenue", "label": "Revenue +12 %"},
        {"id": "customers", "label": "3 new customers"},
        {"id": "pipeline", "label": "Pipeline filled"},
    ],
    edges=[
        {"from": "revenue", "to": "customers"},
        {"from": "revenue", "to": "pipeline"},
    ],
    share=True,
)

print("Share link:", result["share_url"])
