The /api/stealthify/agent endpoint runs a Stealth Agent pipeline: research, generation, humanization, and optional fact-checking and image insertion. It uses the same Stealth API word balance and pay-as-you-go rules as /api/stealthify. Requests can take several minutes. Use a client timeout of at least 10 minutes (the server allows up to 600 seconds).

Usage notes

  • Billing uses output words only: charged words = ceil(outputWords × 10) toward your Stealth API balance (see Pricing).
  • You must have prepaid words or accepted pay-as-you-go terms with a valid payment method when balance is low—same rules as other Stealth API endpoints.
  • Prefer idempotent retries with care: each successful 200 run creates a new run and document and charges credits again.
