| Param | In | Example or values | Meaning |
|---|---|---|---|
| `name` | path | `ascend` (Elysium); `liquidlaunch` (HyperEVM) | Launchpad name (`ascend`, `obol`, `liquidlaunch`, `unknown`…: `name` of GET /v1/launchpads) or one of its contracts |
| `layer` | query | `(empty)`, `elysium`, `hyperevm` | EVM layer |

Elysium:

```bash
curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/launchpads/ascend"
```

HyperEVM:

```bash
curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/launchpads/liquidlaunch"
```

| 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} |
