QuickChart
Render Chart.js charts, QR codes, word clouds, GraphViz diagrams and table images through QuickChart's hosted or self-hosted image API.
OCNORA ships 6 typed QuickChart operations. Each node has a schema-driven form, input and output tables beside its settings, and is pre-flighted by Workflow Health before your first real run. Endpoints not covered by a typed node are called at https://quickchart.io through the HTTP node with the same credential.
Before you connect QuickChart
- Authentication
- API key
- Credential
- the API key, or {"api_key": "…"} — optional, since QuickChart's free tier and a self-hosted instance need none
- Connection test
- Available: the stored credential can be checked against the provider when you add it. This is not a record that a test was run or passed.

A sample QuickChart workflow
- 1A core triggerStart the run from a chat, form, manual, schedule, webhook, workflow trigger — no QuickChart trigger is needed.
- 2Render Chartquickchart.render_chartRender a Chart.js configuration to an image and emit it as a base64 file blob a storage, mail or Slack node can take straight from the wire.
- 3Create Chart URLquickchart.create_chart_urlStore a Chart.js configuration on QuickChart and return a short URL that renders it, so a chart can be embedded in an email or a page without putting the account's API key in front of the reader.
An outline built from this provider’s node contracts, not a recorded run. Each step’s output fields are available to the next in the field picker.
Every node below has a reference page: what it does, the connection it needs, its config fields with types, constraints and examples, and the shapes it emits.

QuickChart questions
- How does OCNORA authenticate with QuickChart?
- With a stored API key credential, shaped the API key, or {"api_key": "…"} — optional, since QuickChart's free tier and a self-hosted instance need none. A connection test can check it when you add it.
- What can I automate with QuickChart?
- 6 typed operations, each with a reference page listing its config fields and the shapes it emits.
- What if the QuickChart operation I need is not listed?
- Call https://quickchart.io from the HTTP node with the same credential, or describe the step to the AI builder, which asks our team for a typed node when one is missing.
- Are there templates that use QuickChart?
- Not yet. Start from a blank workflow, or describe the workflow to Build with AI.
- How are QuickChart calls controlled?
- Every call and every run step is audited, runs count against the execution budget, and Workflow Health pre-flights the workflow when you save it.
