Response fields
| Field | Type | Meaning |
|---|---|---|
name | string | Launchpad name: the `launchpad` filter of GET /v1/launches. `unknown`: the launches no launchpad we know of names (tokens launched by a contract we cannot name yet, or by their creator directly) |
label | string | null | Its display name (as the launchpad writes it); null for `unknown` or when none is held |
launches24h | int | Launches in the last 24 hours |
launches | int | Launches since the chain started |
onCurve | int | Launches still on their bonding curve now |
graduated | int | null | Curve launches that graduated to a DEX pool; null when none of its launches is on a curve (a launch straight into a pool has nothing to graduate from; an Ascend pool's escrow graduation is `ascendGraduation` of its launch row) |
graduationRate | number | null | graduated / curveLaunches, 0 to 1; null as `graduated` |
volume24hUsd | decimal | 24 h volume in USD of its tokens, each in the pool it trades in now (exact sum of the markets list's volume24hUsd) |
top | object | null | Its token with the most 24 h volume; null when none traded in 24 hours: {token, symbol, market, volume24hUsd, mcapUsd} |
daily[] | object | The last 30 UTC days, oldest first: {day, time, launches, graduated} |
