# Token Filters Stream (view)

> A live token filter view: the server maintains the filtered, sorted launchpad view and pushes it - a full `snapshot` on subscribe, then `enter`/`update`/`leave` deltas as tokens move through the lifecycle. Cards are the exact REST `/v1/pulse` shape.

`WS channel: pulse`

A live token filter view: the server maintains the filtered, sorted launchpad view and pushes it - a full `snapshot` on subscribe, then `enter`/`update`/`leave` deltas as tokens move through the lifecycle. Cards are the exact REST `/v1/pulse` shape.

<ParamField body="view" type="string" required>
  `new`, `bonding` or `migrated` - same views as REST. Example: `bonding`
</ParamField>

<ParamField body="chains" type="string" required>
  Comma-separated public chain ids. Example: `evm:8453,solana`
</ParamField>

<ParamField body="limit" type="number">
  View size. Default 50, max 100.
</ParamField>

<Note>Every \~30s the server re-sends an authoritative `snapshot` - replace your local state with it, never merge. Deltas between snapshots keep the view live.</Note>
