As of July 2026, ChatGPT Plus and Pro subscribers can authenticate OpenClaw agents through the Codex OAuth flow. One command does it: openclaw models auth login --provider openai.

That means you can reuse your existing ChatGPT plan. No separate API key needed.

This is a big shift. It removes one of the biggest setup barriers for new OpenClaw users.

This guide breaks down how the Openclaw OpenAI subscription auth works.

You’ll get the real cost per tier, the exact setup steps, and an honest answer to the question that are important: does it hold up for serious automation?

Here’s what we’ll cover:

• How subscription auth compares to API key auth
• What Plus and Pro unlock inside OpenClaw
• Step-by-step setup, from install to your first live task
• Whether it’s reliable enough for production workflows
• Which option fits your use case

Let’s get into it.

Subscription Auth vs. API Key

OpenClaw uses a single provider openai, for both auth methods. That keeps things simple.

You just choose how you want to pay.

Subscription auth routes through the bundled Codex app-server runtime. It bills against your existing ChatGPT Plus or Pro quota.

API key auth is pay-per-token, billed directly by OpenAI. It’s used for non-agent features, or as a fallback when your quota runs dry.

Here’s how the two stack up side by side.

	Subscription (OAuth)	API Key
Cost structure	Flat monthly fee (Plus/Pro), bundled into your existing ChatGPT plan	Pay-per-token, billed as you go
Usage limits	Capped by plan quota (resets periodically)	No fixed cap, scales with spend
Best use case	Regular or moderate agent use, personal automation, everyday tasks	High-volume, continuous, or production workloads
Reliability for long workflows	Can hit quota mid-task on heavy usage	Predictable, won’t throttle unless you hit billing limits
Setup	OAuth login, no key management	Requires generating and securing an API key
Non-agent features (images, embeddings, etc.)	Needs API key	Fully supported

Notice that last row. Subscription auth doesn’t cover everything.

If your agent generates images through the image_generate tool, for example, it still needs an API key behind the scenes for that specific feature.

For everyday agent chat and task work, though, subscription auth is enough for most people.

Cost Breakdown by Tier

Let’s talk real numbers, because this is where most guides get vague.

ChatGPT Plus costs $20/month. It’s the entry point, and it now includes Codex access across web, CLI, IDE extension, and mobile.

Inside a five-hour rolling window, Plus gives you roughly 15 to 90 messages on OpenAI’s top reasoning model, and up to 280 messages on its fastest, lightest model.

The range depends on task complexity and how much context your agent loads at the start of a session.

That’s plenty for personal automations. Think daily reminders, quick research tasks, or a WhatsApp assistant that fields a few dozen messages a day.

ChatGPT Pro starts at $100/month for 5x Plus limits, or $200/month for 20x limits. Both tiers include Codex, plus perks like deep research runs and higher context ceilings.

For OpenClaw users running longer agent sessions, or multiple automations at once, Pro buys real breathing room. The 20x tier especially suits someone running several always-on workflows in parallel.

Practical example: picture a multi-step automation that scrapes a webpage, summarizes it, and sends a Telegram digest. Under Plus, that task might use 5 to 45 credits, depending on the model and how much text it processes. Run that same workflow a dozen times a day, and Plus users on a heavier model may bump into the five-hour cap.

On Pro, that same load barely registers against your quota.

On API key billing, you’d pay per token instead, roughly $1 to $5 per million input tokens depending on the model.

For occasional automations, subscription auth is usually cheaper. For constant, heavy use, metered API billing can work out more predictable.

Step-by-Step Setup

Ready to connect your subscription? Here’s the full flow, start to finish.

Prerequisites:

• Node.js 22 or 24 installed
• OpenClaw installed globally: npm install -g openclaw@latest
• An active ChatGPT Plus or Pro subscription

Step 1: Install daemon

Run this to set up OpenClaw as a background service:

openclaw onboard --install-daemon

This installs the gateway so it keeps running, even after you close your terminal.

Step 2: Authenticate

Now connect your OpenAI account:

openclaw onboard --auth-choice openai

Or, if you’ve already onboarded and just want to add the provider:

openclaw models auth login --provider openai

Either command kicks off the OAuth flow.

Step 3: Browser OAuth vs. headless setup

On a local machine, this opens a browser tab automatically. You log in, approve access, and you’re done.

On a remote VPS, there’s no browser to open. Use the device-code flow instead:

openclaw models auth login --provider openai --device-code

This gives you a short code and a URL. Open that URL on any device, enter the code, and approve.

Example: you’re running OpenClaw on a Truehost VPS over SSH. The device-code flow lets you authorize from your phone, without ever opening a browser on the server itself.

Step 4: Verify

Confirm the connection worked:

openclaw models list --provider openai
openclaw status

You should see your subscription profile listed, along with its quota status.

Step 5: Optional API-key fallback

Want a safety net for when your quota runs out? Set an auth order:

openclaw config set auth.order.openai [subscription, api-key]

This tells OpenClaw to try your subscription first, then fall back to API billing if needed.

Step 6: Connect channels

Now hook up where you’ll talk to your agent:

openclaw channel add telegram

Swap telegram for whatsapp, slack, or discord, depending on where you work.

Step 7: Test it

Send your agent a real task. Something simple works best for a first run.

Then open the Control UI and watch your usage tick up in real time. This is the easiest way to learn how fast your quota burns.

Troubleshooting: if anything breaks along the way, these three commands solve most issues.

openclaw doctor --fix
openclaw logs

Run openclaw doctor --fix first. It repairs common auth and config problems automatically. Then check openclaw status in the Control UI to confirm your quota and connection are both healthy.

Reliability for Production Automation

Here’s the real concern for anyone thinking about scaling up: will your automation run out of credits mid-task?

Subscription auth caps you by plan tier. That cap resets on a schedule, but it doesn’t scale with demand.

API key billing works differently. It’s metered, so it scales with whatever you’re willing to spend.

For continuous or high-volume workloads, that predictability is important. You won’t get throttled mid-workflow just because a lot happened in the last five hours.

Throttling risk is real on subscription auth. If your agent hits a tier limit mid-task, OpenClaw doesn’t just fail silently.

It marks that profile as blocked until the next reset window. If you’ve set up an auth order fallback, it rotates to your next available profile or the API key, without changing your selected model.

Without a fallback configured, though, your agent simply waits.

Example: an agent running a long research task pulls from a dozen sources in a row. If it’s on Plus and hits the five-hour cap halfway through, the task stalls until the window resets or you switch providers.

That’s a real gap if you’re running anything time-sensitive.

Which Tier Should You Pick?

This comes down to how much you run your agent, and how tolerant you are of occasional delays.

Light use: a few automations a day, casual chat, simple reminders. Plus covers this comfortably, at $20/month.

Moderate use: several workflows running daily, some longer research or multi-step tasks. Pro at $100/month (5x limits) gives you real headroom without jumping to metered billing.

Heavy or continuous use: always-on agents, multiple parallel workflows, business-critical automation. Here, either Pro at $200/month (20x) or a straight API key makes more sense. API key billing scales cleanly, without any quota anxiety.

Cost comparison across real workflow types:

• Personal WhatsApp assistant, 20-30 messages/day: Plus is enough, costs stay at $20/month flat
• Daily content research and summarization, moderate depth: Pro 5x handles it, still cheaper than metered billing for most users
• 24/7 customer-facing agent, high message volume: API key billing, cost scales with actual usage instead of a fixed cap

Whichever you choose, none of it works well on a machine that isn’t always online. We’ll get to that.
