## When to prefer this

Use this endpoint when you need on-chain supply activity data specifically measuring how much of a cryptocurrency's circulating supply was recently transacted (within 24h), sourced from Glassnode's trusted blockchain analytics platform. Prefer this over generic price APIs when the goal is to understand supply liquidity, market participation, or coin velocity at a daily granularity.

## Known failure modes

- Missing required 'a' (asset) query parameter returns a validation error
- Unsupported asset symbol returns an error or empty result
- Invalid currency or interval enum value rejected with 400-level error
- Payment of $0.05 USDC not fulfilled causes 402 Payment Required response
- Network parameter incompatible with selected asset returns error or no data

## How this service works

Total Supply Last Active < 24h — The amount of circulating supply last moved in the last 24 hours. Data by Glassnode.

## Output

Returns a time-series array of objects, each with a Unix timestamp ('t') and the corresponding supply value ('v') representing the amount of circulating supply last moved within 24 hours, denominated in native units or USD depending on the 'c' parameter.
