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.far.quest/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 API endpoints!

These APIs are used for far.quest, a Farcaster L1 + L2 client where FIDs are strings and far.quest L2 users can also create data. Feel free to filter out"external":true from responses, and learn more about our Layer 2 here!

Design Philosophy

Our API design is driven by far.quest usage, resulting in speed as a priority over everything. This means our endpoint complexity is minimal, as simplicity drives speed. We do not want to become a slow, bloated API with a billion features. If you want an extremely fast and free API, you've come to the right place!
