OpenAI Agents API hits public beta; Cloudflare ships sandbox integration for cloud Codex agents

ritakozlov · x · 2026-09-11

OpenAI announced the public beta of its Agents API, letting developers build cloud agents on the Codex harness with OpenAI managing orchestration, long-running sessions, and context compaction.

Cloudflare published an official integration showing how to self-host Agents API sessions in Cloudflare Containers: each agent session runs in a Durable Object backed by a container executing codex exec-server, with signed OpenAI webhooks handling session orchestration while workspace files stay in the user's Cloudflare account. Codex connects outbound via a restricted executor API key.

The docs also spell out permissions (api.model.read, api.agents.environments.connect for the executor key; api.agents.read for the Worker) and provide a deploy-to-Cloudflare executor template.
