What is OpenAI Agents API
OpenAI Agents API is a managed version of the Codex harness that lets developers build durable cloud agents with a single API call instead of building their own orchestration. It handles long sessions, smart tool use, and subagents working in parallel, and runs on OpenAI or partner sandboxes. The harness is open source and available in public beta, with no extra fees beyond token and tool usage.
Key Features
Use Cases
- Building durable cloud agents without custom orchestration
- Running parallel subagents for complex tasks
- Automating multi-step developer workflows
Why do startups need this tool?
Startups can ship agent-based products quickly without investing in orchestration infrastructure, since the API manages sessions, tool use, and parallel subagents while charging only for token and tool usage.
