# IDs expire

Every id in the API (`searchId`, trip id, fare id, rate id) is opaque and expires. A `404` on an id that worked before means it expired: create a new search and rethread. Retrying the same id never recovers. Ids are also context bound: a trip id only resolves with the `searchId` it came from.
