description: >-
  Guardant Health publishes no public, self-serve developer API and therefore no
  public rate-limit documentation. Ordering and results integration is delivered
  through institutional EMR interfaces (Epic Aura, Flatiron OncoEMR) whose
  throughput and quotas are governed by partner integration agreements and the
  host EMR, not by a public API gateway. No rate-limit values can be reconciled
  from public sources.
notes: >-
  Reconciled false: no public rate-limit values exist. Any throttling, batching
  or volume constraints are defined per institutional partner during EMR
  onboarding. Update this artifact only if Guardant Health publishes public API
  rate limits.
