Miro API
Miro is an online collaborative whiteboard platform. Its REST API v2 enables agents to create and manage boards, add visual items (sticky notes, shapes, connectors, images, text, cards, frames), and automate whiteboard content. WebSocket support enables real-time board updates.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth2 with board-specific scopes. SOC2 Type II, ISO27001. Enterprise security features available. Whiteboard content may contain sensitive business information.
⚡ Reliability
Best When
An agent generates visual content that humans will collaborate on — diagrams, boards, or structured visual representations of complex data.
Avoid When
Your agent's output is primarily textual or tabular — a doc or spreadsheet tool is more appropriate.
Use Cases
- • Generating visual diagrams or architecture charts from structured agent data
- • Populating retrospective or brainstorming boards with agent-processed input
- • Creating and organizing sticky notes from meeting transcripts or analysis
- • Building real-time monitoring dashboards on Miro boards
- • Automating mind maps or flowcharts from data sources
Not For
- • Data storage or retrieval (Miro is a visual canvas, not a database)
- • Agents needing sub-second write latency at high throughput
- • Document generation where structured output format matters over visual layout
Interface
Authentication
OAuth 2.0 required for all API access. Scopes are granular: boards:read, boards:write, microphone:listen, etc. Access tokens are short-lived with refresh tokens. No API key option for agents — OAuth user context is always required. Miro Apps (installed to workspaces) can use service account tokens for agent automation.
Pricing
Free tier's 3-board limit is a hard constraint for agents that create boards dynamically. Starter plan required for most agent automation scenarios. API access is available on all tiers.
Agent Metadata
Known Gotchas
- ⚠ OAuth-only auth requires initial user authorization — no simple API key for headless agents
- ⚠ Free tier 3-board limit is quickly exhausted by agents that create boards per-task
- ⚠ Item positions on the board use an x/y coordinate system — agents must manage layout explicitly
- ⚠ No idempotency — item creation is always additive; implement state tracking to avoid duplicates
- ⚠ Bulk operations are capped at 300 items per request — large boards require batching
- ⚠ WebSocket connections for real-time updates require separate auth and connection management
- ⚠ Board content queries are paginated but can be slow for large boards with thousands of items
