  The ELSA API is a partner/B2B speech-assessment service. ELSA's developer
  documentation publishes per-request pricing metered per 15 seconds of audio,
  split between scripted and unscripted scoring, across STANDARD and PREMIUM
  plans (the plan is selected per call via the api_plan parameter). Production
  access and contract terms are arranged with ELSA (request an API key /
  contact for business), so the representative rates below are not reconciled.
notes: >-
  Rates below are representative figures published on the ELSA API documentation
  and may change; ELSA partner onboarding is sales-assisted. Verify current
  pricing and plan limits with ELSA during reconciliation.
