All API requests require an API key for authentication.

​
Getting Your API Key

  1. Go to CrawlKit Dashboard
  2. Navigate to API Keys
  3. Click Create New Key
  4. Give it a name (e.g., “My App”, “Production”)
  5. Copy the key - you’ll only see it once!
Your API key looks like this: ck_abc123.... Keep it secret!

​
Using Your API Key

Add the Authorization header to every request: 
Authorization: ApiKey ck_your_api_key_here

​
Example Request

curl -X POST https://api.crawlkit.com/api/v1/crawl/raw \
  -H "Authorization: ApiKey ck_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

​
Managing API Keys

  • Create keys in the dashboard under API Keys
  • Name your keys to remember what they’re for (e.g., “Production”, “Testing”)
  • Delete unused keys to keep your account secure
  • Never share keys in public repos or client-side code
API keys provide full access to your account. Keep them secret!

​
Security Tips

Browser JavaScript can be viewed by anyone. Use a backend proxy instead.
Store keys in .env files, not in your code.
# .env file
CRAWLKIT_API_KEY=ck_abc123...
Create separate keys for development, staging, and production.
If a key might be exposed, delete it immediately and create a new one.
