# Freshness delay and source references

A grant may carry a freshness delay. It applies to every read of its dataset that has a knowledge cutoff: entity, fixture, result and match-fact reads are served as known at `request time - delay` at the latest (`knowledge.known_at` reports the cutoff served), so nothing recorded inside the delay window, such as a kickoff move or a result, is served before the delay has passed. `GET /v1/competitions`, which takes no `known_at`, lists today's names as known at `request time - delay` too. Source references (`sources`) appear only where the rights of the source and your `read:sources` scope permit them.
