Authenticate and understand the limits before your first request

Everything you need to know before your first Build API call lives here:

  • Authentication - send a Bearer API key on every request
  • Regions - eu.api.speechify.ai and us.api.speechify.ai pin where synthesis runs, and are not data residency
  • API Limits - character, rate, and concurrency limits per plan

The official SDKs read SPEECHIFY_API_KEY from the environment automatically. Raw HTTP callers should send Authorization: Bearer YOUR_API_KEY on every request.
