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 X
The beat.rip edge asks api.x.com directly, and nobody in between. X’s own sign-up check username_available.json: valid:true only for a registrable name, reason taken, or is_banned_word for a reserved one. Names of four characters or fewer it will not judge; those and any refusal go to publish.x.com oEmbed (200 with a timeline for a public account, 404 for none, which suspended and protected accounts also give).
Requests are paced to one request at a time, 500 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://x.com/name, with your name in place of “name”, so you can confirm by hand.
What each answer means on X
- Taken
The platform’s own endpoint returned an account for the username.
- Available
X’s sign-up check: available.
- 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.
Questions about X usernames
How long can a username be on X?
Between 1 and 15 characters.
Which characters can a username use on X?
Only letters, digits and underscores. Capitals are allowed, and Beat.rip lowercases every name before asking, so it checks the lowercase form. The platform’s own rule: max 15, letters digits underscore only.
Can Beat.rip tell whether a username is free on X?
Yes: X’s own sign-up check answers, and only that earns “available”. It is still not a reservation; someone can sign up first.
Does checking a username on X reserve it?
No. Beat.rip cannot sign up on your behalf; claim the username on X itself. Availability changes by the minute.
