OpenAI Agents API, explained.
OpenAI Agents API is designed for developers building durable cloud agents with managed context, tools, optional subagents and configurable execution environments. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.

Cost reality
The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.
Budget for the result, not the plan badge.
