X (Twitter) Credential Checker

Verify the credentials from your X Developer Portal before you build against them. It calls GET /2/users/me to fetch your own profile, so a green result means the creds actually work. Everything is sent only to api.x.com; nothing is stored or logged here.

OAuth 1.0a (4 keys)

Bearer / user token

From the portal's Keys and tokens tab — the classic user-context keys used for posting, following, etc.

API Key (consumer key) API Key Secret Access Token Access Token Secret

A single token: either an app-only Bearer token (from Keys and tokens) or an OAuth 2.0 user access token (from the OAuth2 flow). A user token can fetch your profile; an app-only token can only look a username up.

Bearer / access token Username to look up (only needed for app-only tokens)
