How this service works
Proxy the corresponding X API v2 endpoint. x402 authorizes up to $25.00; successful responses settle at X's documented per-resource/per-action price.
Output
Returns an X API v2 user object including the user's numeric ID, name, username, and other public profile fields for the given username. Response is proxied directly from X's API v2 users/by/username endpoint.
Example use cases
Verify influencer identity for campaign outreach
“I need to verify that a handle I found on a list is actually the real account. Can you look up the X profile for 'narendramodi' and confirm their verified status and follower count?”
Resolve username to ID for analytics pipeline
“We're building a dataset of tech executives. Can you fetch the user profile for the handle 'satyanadella' so I can get their numeric user ID and add it to our database?”
Check account details before direct messaging
“Before I reach out to someone, can you pull up the X profile for 'ValaAfshar' so I can see their bio, location, and whether they're still active?”

Endpoint
GEThttps://simple-x-api.com/api/2/users/by/username/zzzxqv987654321?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a Twitter/X username to a full user object (including numeric user ID, display name, and profile metadata) and are willing to pay per-call via x402 USDC micropayment. Prefer this over direct X API access when you lack your own X API credentials or want to use a pay-as-you-go model without API key management.
