Public API for Agent Builder — listing and managing agent configurations?

Is there a public API (or a planned timeline) for programmatically accessing Agent Builder configurations?
Specifically, we’re looking for endpoints to:

  • List agents/workflows created in Agent Builder
  • Get agent details — model, instructions, temperature, top_p
  • Get tool configurations — MCP server connections, web search, code interpreter, file search
  • Get associated resources — linked vector stores, files
  • Get metadata — creator, created/updated timestamps, versioning

We understand the Responses API replaces the execution side of Assistants(soon to be deprecated), but there doesn’t seem to be a
replacement for the management/configuration side — i.e., no equivalent of GET /v1/assistants for Agent Builder workflows.

Our use case is security and access governance — we need to inventory what agents exist, what models and tools they’re connected to, and who created them. We can see this data in the dashboard but can’t access it programmatically.

Is this on the roadmap? Any rough timeline?
