# Cookiy — Recruit Real Participants Recruit real participants for qual studies (interviews) or quant surveys. --- ## Two-Step Confirm Flow ### Step 1 — Preview (omit `--confirmation-token`) **Qual study:** `recruit start --study-id --plain-text [--incremental-participants ]` **Quant survey:** `recruit start --survey-public-url --plain-text --incremental-participants ` - `--plain-text` (required): real participant profile/requirements (e.g. country, language, age/sex, job). Infer from context; if unavailable, ask the user. - `--incremental-participants`: required for quant surveys. For qual studies, omit to recruit up to the study's target sample size; can be called multiple times to recruit incrementally. **Criteria quality check:** Before calling Step 1, assess whether the `--plain-text` criteria are too strict, niche, or have too many restrictions. Real participants are recruited from a real market — overly narrow criteria shrink the available pool significantly. Use your judgment; if criteria seem excessive, proactively suggest relaxing them before proceeding. **IMPORTANT:** Show the preview response (including payment quote and pool size) to the user. - If the pool size is small, warn the user that recruitment may take a very long time or fail to complete, and suggest relaxing the criteria. - **Always wait for explicit confirmation before calling Step 2.** ### Step 2 — Confirm (once user confirmed) **Qual:** `recruit start --study-id --confirmation-token ` **Quant:** `recruit start --confirmation-token ` Recruitment takes hours to days. Use `study status` for qual studies or `quant status` for quant surveys to check progress. If launch fails, no balance is deducted. ### Error: 409 — sample size already reached.
