How this service works

Get detailed social signal profile for a specific X user.

Technical details

Endpoint

GEThttps://api.messari.io/signal/v1/x-users/*

When to prefer

Use this endpoint when you need a rich, single-user social signal snapshot for a specific X account in the crypto space — including AI-generated narrative insight, mindshare, sentiment, and engagement metrics in one call. Prefer this over the ranked list endpoint when you already know the user and want depth rather than breadth, and over the historical endpoints when you need current snapshot data rather than time-series.

Side effects

Invalid or nonexistent X user ID returns a 404 or empty data response
Rate limiting or quota exhaustion returns a 429 error
Payment not received or insufficient funds returns a 402 error
Malformed xUserID path parameter may return a 400 bad request
User exists but has insufficient signal data to generate profile
