Glossary
Copy page
The terms these docs use, each defined once and linked from its first use on every page.
As-of timeLink to this section
When a value was true, in the as_of field. For a derived value, the time of its newest input.
CreditLink to this section
The one unit Kelly meters: one cached engine read. Every operation has a whole-credit price, the same on every surface.
CursorLink to this section
An opaque string in next_cursor that fetches the next page of a list. Send it back unchanged with the same filters.
DeltaLink to this section
One change to a Kelly Wire topic, whose seq is the previous one plus one.
Key scopeLink to this section
A permission an API key holds, such as read:reference. An operation that needs a scope the key lacks answers insufficient_scope.
Problem detailsLink to this section
The RFC 9457 error body every failed call returns, with a stable code.
ProvenanceLink to this section
Who produced a value and when it was true: the source and as_of every value carries.
Request IDLink to this section
The ID of one call, in the Request-Id header and in every error body. Quote it to support.
SnapshotLink to this section
A Kelly Wire topic's whole current state, with its last seq. It comes first after you subscribe, and again after a gap.
Test modeLink to this section
Keys and tickets that serve recorded sample data instead of live data.
TicketLink to this section
A single-use credential that lives 60 seconds and opens one Kelly Wire connection or stream, so a long-lived key never goes in a socket URL.
TopicLink to this section
One stream of live values on Kelly Wire, such as one market or one game, named like market:{market_id}.
