How this service works
Look up a public X user by numeric ID. Same fields as username lookup. e.g. GET /users/by/id?id=44196397
Output
A JSON object containing the user's numeric ID, username handle, display name, and follower count (e.g. {"data":{"id":"44196397","username":"elonmusk","displayname":"Elon Musk","followersCount":200000000}}). Returns data for a single user matching the provided numeric ID.
Example use cases
Resolve influencer identity from numeric ID
“I have the numeric X user ID 783214 — can you look up that account and tell me the username and how many followers they have?”
Enrich dataset with Twitter profile info
“For each X user ID in my list, look up their display name and follower count so I can enrich my spreadsheet with that info.”
Verify public account details
“Can you fetch the public profile for Twitter user ID 17919972 and confirm what their current username and display name are?”

Endpoint
GEThttps://x-data-gateway.annushka1190.workers.dev/users/by/idWhen to prefer
Use this endpoint when you have a numeric X/Twitter user ID and need to resolve it to a username, display name, or follower count without setting up a Twitter Developer account or managing API keys. Ideal for agents needing quick, pay-per-request identity resolution on X with no subscription overhead. Prefer this over the Twitter API directly when you want frictionless micropayment access via x402/USDC.
Side effects
- Invalid or non-numeric user ID returns an error response
- User ID not found (deleted or suspended account) returns empty or 404-style error
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting or worker errors if the upstream X API is unavailable
- Providing a username instead of a numeric ID will fail since only numeric IDs are accepted
