How this service works
Look up up to 10 X (Twitter) accounts by username in one call. Returns each found profile with public metrics (followers, following, tweets, listed), verification status and bio, plus the list of usernames X did not resolve.
Output
Returns a JSON object with a count of found users, an array of user objects each containing numeric ID, display name, username, bio/description, location, profile URL, profile image URL, follower/following/tweet/listed counts, verified flag, verification type (e.g. 'business'), account creation timestamp, and protected status. Also includes a 'notFound' array of usernames that could not be resolved, plus a 'fetchedAt' timestamp and source label ('x-api-v2').
Example use cases
Influencer vetting before brand deal
“Can you pull up the X profiles for 'lex_fridman', 'naval', and 'balajis' — I need their follower counts, whether they're verified, and their bios so I can decide which ones to reach out to for a sponsorship.”
Resolving X handles to numeric user IDs
“I need the numeric user IDs for these Twitter handles: 'openai', 'anthropicai', and 'deepmind' — can you look them up for me?”
Checking if a newly registered username exists
“Can you check whether the X username 'agent402official' actually exists and if so tell me when the account was created and how many followers it has?”
Technical details
Endpoint
POSThttps://agent402.tools/api/x-users-lookupWhen to prefer
Choose this endpoint when you need structured public profile metadata — follower counts, verification type, user IDs, bios — for up to 10 X usernames in a single no-signup, no-API-key call paid per-use in USDC. Prefer it over maintaining your own X API credentials when you need lightweight, ad-hoc social profile lookups without a long-term subscription, or when building an agent that must resolve X handles to numeric IDs or validate account existence on demand.
Side effects
- Username not found: listed in 'notFound' array rather than throwing an error
- More than 10 usernames submitted: may return an error or truncate results
- Invalid input format (non-string items): request validation error
- X API rate limiting or downtime: upstream error propagated
- Payment failure (insufficient USDC balance): 402 Payment Required before query executes
