API Keys

API keys authenticate your requests to Context7's documentation services.

Managing API Keys

Creating API Keys

Generate a new API key in four simple steps:

1. Click "Create API Key" in the API Keys card
2. Enter a name (optional but recommended)
   • Use descriptive names like "Cursor", "Claude", "VS Code", or "Windsurf"
   • This helps you identify keys later
3. Copy the key immediately
   • Keys are shown only once for security
   • Format: ctx7sk-**********************
4. Use in your requests or add to your MCP configuration:

curl "https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=routing" \
  -H "Authorization: Bearer YOUR_API_KEY"

<Warning>Store your API key securely. You won't be able to see it again after creation.</Warning>

Revoking Keys

Remove API keys you no longer need:

1. Click the delete button next to the key
2. Confirm deletion in the modal
3. Key deactivates immediately - all requests using it will fail
