Researcher API Reference

Complete API for interview creation, study guide design, recruitment, conversation analysis, and wallet management.

Base URL: https://api.avoko.ai/api/v1

Overview

The Researcher API uses a slug-based design — all interview operations reference the interview slug, a short URL-safe string (e.g. a1b2c3d4) returned when you create an interview. You never need internal UUIDs.

Study guide items use readable IDs (S1, Q1, T1) for sections, questions, and tasks.

Errors & Rate Limits

Error format

{
  "detail": "Interview not found"
}

Some endpoints return structured errors with error.code and error.message fields.

HTTP status codes

Code	Meaning	Common cause
400	Bad request	Invalid params or illegal state transition
401	Unauthorized	Missing or invalid API key
402	Payment required	Insufficient wallet balance to launch recruitment
403	Forbidden	No active subscription or wrong role
404	Not found	Interview slug not found
409	Conflict	E.g. recruiting on unpublished interview, or study already active
422	Validation error	Missing required fields or invalid types
429	Rate limited	Too many requests — wait and retry

Interview state machine

draft → published → active ⇄ paused
↓ ↓
awaiting_review → completed

API calls that violate the state machine return 409 Conflict. E.g. you cannot launch recruitment on a draft (must publish first), or pause a completed interview.
