Some endpoints don't query the source when you call. They answer from a complete copy of it that Croma keeps up to date and organized for querying: these are **dataset endpoints**. The rest are [live lookups](/live-lookups). A dataset endpoint: * answers in milliseconds and never becomes an [async job](/async-jobs), * keeps answering when the source is down or in maintenance, * searches everything the source has published, not one record per call, * spends **1 credit** per request instead of the live 10 (see [Credits](/credits)). ## `as_of` Every dataset-served response carries `as_of`: the data is current up to that moment. ```json theme={"dark"} { "data": { "as_of": "2026-09-07T05:12:44Z", "results": [] } } ``` Each dataset refreshes on its own schedule. If you need the source's answer as of this second, use a live endpoint where one exists. ## Lookups A third answer mode sits between the two. A **lookup endpoint** reads one record by its key. The first time a key is asked, Croma reads the source and keeps the answer; every call within the endpoint's freshness window answers from that copy in milliseconds and spends nothing at the source; past it, the source is read again. Croma also re-reads stored answers on a schedule, so a value the source changes on its own calendar is caught up with. Every lookup response says when the source was last asked and where the answer came from: ```json theme={"dark"} { "data": { "found": true, "checked_at": "2026-10-06T14:02:11Z", "served_from": "copy" } } ``` `served_from` is `copy` (answered from Croma's copy), `upstream` (the source was read for this call) or `stale` (the source could not be read and the stored answer stood in, with a warning). A key the source has nothing under returns `found: false` and is asked of the source again next time. Lookup endpoints carry the **Lookup** pill in their guide and `served_from: "lookup"` in the catalog, and are metered as live requests. ## Which endpoints are dataset-served? | Source | Dataset-served
