Design APIs built for autonomous agents.

Traditional approach

1
Apply for Canva access
Developer account, app review, OAuth setup
2
Manage OAuth2 tokens
PKCE flow, token refresh, session storage
3
Handle complex formats
Design types, export compatibility, asset polling
4
Monitor usage & billing
Track API calls against rate limits

StableDesign

1
One endpoint
Create, list, export, upload — all in one API
2
Pay per request
Pennies when you use it, nothing when you don't
3
No credentials
Payment is authentication
4
Agent decides
Budget constraint, autonomous execution

Try it

Use an MPP-compatible client (e.g. mppx CLI) for the 402 payment flow. A one-time Canva OAuth setup is required — visit /api/oauth/authorize in a browser.

# List your Canva designs (requires MPP payment)
curl https://stabledesign.vercel.app/api/designs/list

# Create a presentation
curl -X POST https://stabledesign.vercel.app/api/designs/create \
  -H "Content-Type: application/json" \
  -d '{"preset": "presentation", "title": "Q4 Report"}'

# Export a design to PNG
curl -X POST https://stabledesign.vercel.app/api/designs/export \
  -H "Content-Type: application/json" \
  -d '{"design_id": "DAGabc123", "format": {"type": "png"}}'

Designs that cost less than they're worth.

Hand your agent a brief. Let it create, iterate, and export. Pennies per design, dollars per campaign.
