Key point
Coasty has launched a managed API for AI agents that perform computer control and automation tasks.
Details
Coasty provides an API service for developers building Computer-use agents. Users can run autonomous tasks on managed machines and compose them into complex workflows.
The key features and hierarchy are as follows:
- Primary Automation: Supports high-level automation through Task runs, Workflows, and managed Linux/Windows machines (Machines).
- Primitives: For cases requiring finer control, developers can directly control primitives such as the stateless Predict, the stateful loop Sessions, the coordinate-finding Ground, and the code-to-action Parse.
Developers can generate prompts optimized for various LLMs such as Cursor, Claude Code, and ChatGPT to improve agent execution performance.
