Custom Instructions

Inject your own AI prompts to extract domain-specific insights from every transcription. Build QA scorecards, compliance checklists, and custom analysis workflows. Requires Pro plan ($0.39/hr).

How It Works

Pass an instructions field with your custom prompt (max 2,000 characters). The AI will process your prompt against the full transcript and return structured results in ai_analysis.custom_instructions_result.

curl
curl -X POST https://api.voxparse.com/v1/transcribe \
  -H "X-API-Key: YOUR_API_KEY" \
  -F "[email protected]" \
  -F "plan=pro" \
  -F "instructions=Score this call 1-10 on: greeting quality, problem resolution, upsell attempt. Return JSON with scores and reasoning."

Security

Injection protection: Custom instructions are sanitized server-side to prevent prompt injection attacks. Instructions attempting to override system behavior are silently dropped.

Maximum length: 2,000 characters. Included in the Pro plan rate ($0.39/hr) at no extra cost. Custom instructions are not available on the Lite plan.
