WS channel: pulse-pools Enabled on your key on request: contact us. A live launchpad column with one row per pool: the full list on subscribe, then every pool that enters, changes or leaves, as it happens. Same parameters, filters and messages as the Pulse Stream, which gives one row per token. Use it when the pool is what you track: a pool-level terminal, liquidity tooling, or a view where the same token can appear once per pool.

What differs from the Pulse Stream

	`pulse`	`pulse-pools`
One row	per token	per pool
Row `key`	`<chain>:<token address>`	`<chain>:<pool address>`
`pool`	the pool displayed for the token	the pool of the row
`pools`	every known pool of the token	not present
Counters and windows (`txns`, `volumeUsd`, `windows`…)	of the token	of the pool
Wallet counts per window (`windows.<w>.uniqueBuyers`, `uniqueSellers`, `traders`, `snipers`, `proTraders`)	across the token’s pools	of the pool
Holders (`holdersCount`, `top10HoldersPct`, `devHoldingsPct`)	of the token	of the token: every pool row of a token carries the same `holdersCount` and `top10HoldersPct`; `devHoldingsPct` is the share of the row’s own `creator.address` (`null` on a pool whose creator is not the token’s)

Everything else is identical: the columns (new, bonding, graduated), mixing chains, limit, sortBy, sortOrder, updatePeriod, windows, the filter tree and the flat REST filters, the snapshot then delta delivery, rank and order, the free snapshot every 60 s, since, errors and close codes. The Pulse Stream page is the reference for each of them.

Parameters

string

required

The column: new, bonding or graduated (migrated is accepted as an alias of graduated). Example: bonding

string[]

required

1 to 8 public chain ids, evm:<id> or solana. EVM chains and Solana can be mixed in one view. Example: ["evm:8453"]

number

View size, 1 to 100. Default 50.

string

Any numeric card field. Default: the date of the column, most recent first (bondingProgress on bonding).

string

asc or desc. Default desc.

object

A filter tree, same grammar and same fields as the Pulse Stream.

integer

Milliseconds, 0 to 60000, default 100: at most one delta per period. Same rules as the Pulse Stream; the ack carries the value applied.

string[]

The rolling windows to include in each row, among 1m, 5m, 15m, 30m, 1h, 4h, 6h, 12h, 24h. Default: none. Same rules as the Pulse Stream.

Applying a delta

Remove every key listed in leave.
Apply every update: the fields present replace those of the row.
Insert every row of enter at its rank, in the order given.
If order is present, arrange your rows in that order.

A snapshot replaces everything you hold for the view.

Billing

1 credit per message delivered. The snapshot of a subscription ("reason": "subscribe") costs 1, whatever its size; every delta costs 1, whatever it carries. Snapshots sent on our own after that first one ("reason": "periodic" every 60 s, "reason": "resync" after a hiccup) and deltas flagged "replay": true are free; the snapshot sent when you resume with since costs 1, like the one of a new subscription. The connection is free. A longer updatePeriod means fewer messages, and fewer credits. GET /v1/usage/breakdown reports this channel under WS pulse-pools, where requests is the number of messages delivered.

Ack

type:object

Server acknowledgement: the subscription is live.

Delta

type:object

Each change of the view, at most one per updatePeriod: 1 credit per message.

type:object

Client frame opening the subscription (additive, ack is explicit).
