Ask a person to complete a real-world task from your software.

Your software or AI agent describes the action and the result it needs. Fangst returns a hosted task link. The person completes it and reports the outcome.

From API call to structured result.

  1. Create the taskSoftware or an AI agent describes the action and the evidence it needs.
  2. A person does the workThe person opens the hosted page, completes the action, and reports the result.
  3. Read the outcomeFangst returns structured findings and files through the API or a webhook.

Get a structured outcome, not a status message.

Specify the reading, photographs, and confirmation required for the task to count as complete.
