Endpoint

GEThttps://api.messari.io/signal/v1/assets/time-series/1h

When to prefer

Use this endpoint when you need fine-grained (hourly) social signal tracking for a crypto asset, especially for intraday analysis of mindshare shifts, sentiment swings, or momentum changes. Prefer the daily endpoint for longer-horizon trend analysis. Choose this over generic price APIs when social/community signal data is the primary need.

Side effects

Missing required 'granularity' parameter returns a 400 validation error
Invalid or unknown assetID may return empty data or 404
Invalid date format for start/end returns a parsing error
Requests without valid x402 payment result in 402 Payment Required
Time range too large may result in pagination truncation or timeout
