Farcaster username rules
- Length
- 1 to 16 characters
- Characters
- Lowercase letters, digits and hyphens. No capitals: the charset is lowercase only. Beat.rip lowercases what you type, so “Name” is checked as “name”.
Beat.rip checks these rules on your device before any request. A username that breaks them is marked invalid, never available, and no request is sent for it.
How Beat.rip checks Farcaster
The beat.rip edge asks fnames.farcaster.xyz directly, and nobody in between. The fname registry’s own transfer log: the latest transfer to a non-zero fid is the current owner; no transfers means unregistered.
Requests are paced to at most 2 requests at a time, 200 ms apart, identify themselves as beat.rip, and each answer is cached for seconds to minutes, so a busy minute never hammers the platform.
Every result row links to https://farcaster.xyz/name, with your name in place of “name”, so you can confirm by hand.
What each answer means on Farcaster
- Taken
The platform’s own endpoint returned an account for the username.
- Likely free
No account at the Farcaster name registry’s own endpoint. Likely free, but a name can still be reserved, suspended or held.
- Unknown
The platform refused, rate-limited or answered something unrecognised. The row says which and links to the profile.
- Invalid
The username breaks one of the rules above, so nothing was asked.
