# Plan quotas and limits

The quota counts cars, not requests; the rate is limited in requests per second.

## What the quota counts

The catalog and the change feed count the cars and events returned, not requests: a response with 37 cars costs 37 records, an empty one costs nothing. The demo counts every data request. References, usage, photos and health checks are free.

## Plans

| Plan | Quota | Markets | Req/s | limit | Feed | Live US |
| --- | --- | --- | --- | --- | --- | --- |
| Demo | 100 requests a day | 3 | 1 | 20 | ✓ | — |
| Start | 100,000 cars a month | 1 | 2 | 100 | — | — |
| Pro | 500,000 cars a month | 2 | 5 | 100 | ✓ | 2,000 |
| Max | 2,000,000 cars a month | 3 | 10 | 100 | ✓ | 10,000 |

Usage at any moment: [GET /v1/usage](https://apiauto.space/en/docs/endpoints/usage/); what is left is in the X-Quota-Remaining header of every answer.

## Reset and renewal

The monthly quota renews on the 1st at 00:00 UTC. After the paid period ends the key works for 3 more days at a fifth of the plan's rate (at least 1 request per second), then answers 401 — renewing within 90 days keeps the same key.
