Endpoint

When to prefer

Use this endpoint when you need time-series data on past token unlock events for a specific crypto asset, including USD valuations and cumulative supply release totals. Ideal for analyzing vesting schedules, supply inflation pressure, or comparing unlock cadences across date ranges. Prefer this over real-time or scheduled unlock endpoints when historical context or trend analysis is needed.
