Getting a free API Key

Start by creating a free API key! We use API keys to prevent abuse.

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "description": "YOUR_DESCRIPTION",
    "email": "YOUR_EMAIL"
  }' \
  https://build.wield.xyz/apikey/create

Field	Description	Example
`YOUR_DESCRIPTION`	The name and description of the project.	`Project X`
`YOUR_EMAIL`	Your email address for any notifications.	`[email protected]`

You'll use this API key as a request header in your HTTP request (API-KEY). For Authentication, use farquest-default-auth-token from your cookies formatted as Bearer ${token}.

Now you can access our free & open-source Farcaster L1 + L2 API endpoints!
