## What Happened?

Your request was too big! We limit how much data you can send in a single API request to keep everything running smoothly.

This usually happens when you're trying to send a lot of data at once - like huge metadata objects or really long strings in your request.

## How to Fix It

### 1. Trim Down Your Request

The most common cause is putting too much data in the `meta` field or other parts of your request.

<CodeGroup>
  ```bash Too Big theme={"theme":"kanagawa-wave"}
  curl -X POST https://api.unkey.com/v2/keys.create \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer unkey_XXXX" \
    -d '{
      "apiId": "api_123",
      "name": "My Key",
      "meta": {
        "userProfile": "... really long user profile data ...",
        "settings": { /* huge nested object with tons of properties */ }
      }
    }'
  ```

  ```bash Just Right theme={"theme":"kanagawa-wave"}
  curl -X POST https://api.unkey.com/v2/keys.create \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer unkey_XXXX" \
    -d '{
      "apiId": "api_123",
      "name": "My Key",
      "meta": {
        "userId": "user_123",
        "tier": "premium"
      }
    }'
  ```
</CodeGroup>

### 2. Store Big Data Elsewhere

Instead of cramming everything into your API request:

* Store large data in your own database
* Only send IDs or references to Unkey
* Fetch the full data when you need it

## Need a Higher Limit?

<Note>
  **Got a special use case?** If you have a legitimate need to send larger requests, we'd love to hear about it!

  [Contact our support team](mailto:support@unkey.com) and include:

  * What you're building
  * Why you need to send large requests
  * An example of the data you're trying to send

  We'll work with you to find a solution that works for your use case.
