MultiOn API
AI web agent API that executes natural language web tasks via a managed browser. MultiOn's API takes a user command ('book a table at X restaurant for 2 people on Friday') and executes it autonomously in a browser, returning results. Designed as an action API for AI agents that need to perform web tasks — buying, booking, searching, filling forms — without custom browser automation code.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. Browser sessions may handle sensitive credentials — trust model is important to evaluate before production use. Actions are real and irreversible — security controls critical. SOC2 status not confirmed.
⚡ Reliability
Best When
Your AI agent needs to take real-world web actions (book, buy, submit, navigate complex portals) and you don't want to write custom browser automation for each website.
Avoid When
You need fast, predictable, structured data extraction from known websites — use traditional scraping tools. MultiOn's strength is task completion, not high-speed data extraction.
Use Cases
- • Execute web tasks programmatically for agents — shopping, booking, form submission — via natural language commands without browser automation code
- • Give AI assistants the ability to 'browse the web' and take real actions via MultiOn as a managed web agent capability
- • Build agent pipelines that delegate web-based data gathering or action execution to MultiOn as a specialized web operator
- • Automate repetitive web workflows (report downloads, portal data extraction) with natural language task descriptions
- • Enable agent-to-web interactions for services without APIs by describing tasks in plain English
Not For
- • High-frequency, high-volume web automation — MultiOn is designed for task-per-request pattern, not bulk scraping
- • Applications requiring deterministic, selector-based automation — MultiOn's LLM approach is non-deterministic
- • Cost-sensitive applications doing simple web scraping — cheaper to use Playwright or BeautifulSoup for structured data extraction
Interface
Authentication
API key passed in X-API-Key header. Key generated in MultiOn dashboard. No scope granularity — single key grants access to all API methods.
Pricing
MultiOn charges per session or task execution. Pricing varies by task complexity and duration. Detailed pricing requires account signup. LLM costs are included in MultiOn pricing.
Agent Metadata
Known Gotchas
- ⚠ Tasks may return 'paused' status requiring human input — agents must handle the PAUSE state and decide whether to continue, provide input, or abort
- ⚠ Task execution is non-deterministic — the same command may produce different navigation paths on different executions depending on website state
- ⚠ Sessions have time limits — long-running tasks may timeout; agents should set appropriate session duration expectations
- ⚠ Actions are real and irreversible (purchases, bookings, form submissions) — agents must implement safety checks before executing real-world actions
- ⚠ Website login handling requires passing credentials as part of task context — credential management is agent responsibility
- ⚠ Rate limits on concurrent sessions can queue tasks — time-sensitive agent workflows must account for potential queuing
