Beyond Browsing: API-Based Web Agents
AI Web agents ditch clicking buttons, talk directly to servers through APIs to get tasks done faster.

Original Problem 🎯:
Web agents primarily rely on browser interfaces designed for humans, making them inefficient for machine-to-machine interactions. Current web browsing agents achieve limited success rates due to complex GUI navigation and accessibility tree limitations.
Solution in this Paper 🔧:
• Introduces two agent types: API-Based Agent and Hybrid Agent
• API-Based Agent directly communicates with web services through documented APIs
• Hybrid Agent combines API calls with web browsing capabilities
• Implements two-stage documentation retrieval for large API sets
• Uses GPT-4 to generate documentation for undocumented APIs
• Leverages OpenHands framework for agent evaluation and development
Key Insights from this Paper 💡:
• APIs offer more efficient task completion compared to browser-based interactions
• API availability and quality significantly impact agent performance
• Hybrid approach provides flexibility to handle both API-supported and unsupported tasks
• Well-documented APIs lead to higher success rates in task completion
• Manual API integration remains a current limitation
Results 📊:
• Hybrid Agent achieves 35.8% success rate on WebArena benchmark
• API-Based Agent outperforms browsing agents by 15% on average
• Hybrid Agent shows 20% absolute improvement over web browsing alone
• Best performance on GitLab (44.4%) and Map (45.9%) tasks
• Reduced number of steps: API agent (7.8) vs Browsing agent (8.4)
🚀 How do the three types of agents (Browsing, API-Based, and Hybrid) compare in performance?
Browsing Agent: 14.8% average success rate using only web browsing actions
API-Based Agent: 29.2% average success rate using only API calls
Hybrid Agent: 35.8% average success rate by combining both methods The Hybrid Agent outperforms both other approaches by dynamically switching between API calls and web browsing based on task requirements.
