this plugin lists.

02Bring your own key, or hosted

How you
pay for it.

No API key at all: Codex on a computer you registered runs the agent, signed in with your own ChatGPT plan, and the model bill goes there. Start the NextOS bridge on that machine and pick Codex under Settings > Privacy > Background runs.

  • Full tool calling - agents can use every app and MCP tool through this provider
  • No provider-hosted web search
  • No provider-hosted URL fetch

03Governance

The same controls
as every provider.

  • Restrict which providers and models a team may use at all - an allowed list on the org policy, enforced on every gateway call
  • Set a default model the whole workspace inherits, with per-agent pins for the job that needs a different one
  • Per-org and per-key budgets and rate limits, checked before a call reaches the provider
  • Guardrails (PII redaction, prompt-injection screening) applied to every request and response, regardless of provider
  • A full audit trail of governance and budget events, in the team's activity log

04Over the gateway

One endpoint,
OpenAI-compatible.

gateway — next.os
curl https://www.jonkum.in/api/v1/chat/completions \
  -H "Authorization: Bearer ngk_..." \
  -H "X-Provider-Key: your-codex-key" \
  -H "Content-Type: application/json" \
  -d '{"model":"codex/default","messages":[{"role":"user","content":"..."}]}'

Omit X-Provider-Key to run on the account's hosted allowance instead, where the plan supports it. See the gateway page for the full API.

05Every other provider

one plane · every provider · your key or ours
