# Extended history

> Extended Global Nodes keep more history than a standard full node — more retention than Full, without being a complete archive — with no change to request-unit billing.

Some Chainstack [Global Nodes](/docs/global-elastic-node) carry an **Extended** label. An Extended node is a full node that keeps more history than a standard full node of the protocol — more retention than a plain Full node, but not a complete archive from genesis.

It exists because Full and Archive don't describe these nodes well. A standard full node keeps only a short recent window, an archive node keeps everything from genesis, and Chainstack Global Nodes for some protocols sit in between. **Extended** is the honest label for that middle ground: more than Full, less than Archive.

## Billing

Extended is not a new billing class. Requests are billed exactly as on a Full node, with no request-unit change. See [Request units](/docs/request-units).

## Availability

* Global Nodes only.
* The label maps to the actually deployed node configuration, so it appears only where the node genuinely serves extended history — never on a standard full node.

## How much history you get

The exact window depends on the protocol and moves over time, so read it from the node at runtime rather than assuming a fixed depth:

* **Sui** — serves checkpoint history from genesis, well beyond the \~2 epochs (\~48 hours) a standard Sui full node keeps locally. See [Sui tooling](/docs/sui-tooling).
* **XRP Ledger** — keeps more recent ledgers than a default `rippled` server. Read `complete_ledgers` from `server_info`. See [XRP Ledger tooling](/docs/xrpl-tooling#how-much-ledger-history-your-node-holds).
* **Stellar** — keeps an extended retention window plus full `getLedgers` history. Read the window from `getHealth`. See [Stellar tooling](/docs/stellar-tooling#historical-data-availability).
