Plans & Rate Limits
The Public AI Gateway offers four usage tiers. Rate limits apply per API key and are enforced on every request.
Tiers
| Tier | Rate Limit | How to Get It |
|---|---|---|
| Free | 100 requests/minute | Default when you create an API key |
| Plus | 200 requests/minute | Contribute via OpenCollective |
| Pro | 300 requests/minute | Contact [email protected] |
| Enterprise | 10,000 requests/minute | Contact [email protected] |
Upgrading Your Plan
Free (default)
Every new API key starts on the Free tier. Create an API key after signing in to get started.
Plus
Support Public AI through OpenCollective. To receive the Plus tier upgrade:
- Create at least one API key in this developer portal
- Contribute using the same email address as your portal account
Your rate limit will be upgraded to 200 requests/minute once your contribution is processed.
Pro and Enterprise
For higher rate limits or custom arrangements, email [email protected] with your account email and use case.
Usage Billing
Rate limits and token usage billing are separate:
- Rate limits control how many requests you can make per minute (based on your tier above)
- Token usage is billed against wallet credits on the Billing page
New accounts receive starter credits when they first use billing features. You can add a payment method and top up your wallet to continue using models beyond your free credits. Per-model token pricing is shown on the Billing page.
Rate Limit Exceeded
When you exceed your tier's rate limit, the API returns a 429 Too Many Requests response. Wait for the rate limit window to reset (one minute) before retrying, or upgrade your plan for a higher limit.
