Lookups
Reference data — the IDs the gateway will accept on job and site operations.
All lookups respond with { "items": [...] }. Results are scoped to what your key can see and capped at 100 items per call. Lookups require the jobs:read scope.
These IDs change rarely (only on operator action). Cache the results in your application — refresh on a daily schedule, or on demand if a lookup fails. See Rate limits for why this matters.
