# Deutero Python SDK

> Official Python SDK for the Deutero Study Management API: design AI-moderated interview studies, recruit participants, rehearse with AI personas and analyze responses.

- [Deutero Python SDK](https://docs.deutero.ai/index.md): Run AI-moderated research interviews from Python: design studies, recruit participants, rehearse with AI personas and analyze what people said.
- [Quickstart](https://docs.deutero.ai/get-started/quickstart.md): Install the SDK and take a study from nothing to a shareable participation link.
- [Authentication](https://docs.deutero.ai/get-started/authentication.md): Provide your Deutero API key to the client.
- [Async usage](https://docs.deutero.ai/get-started/async.md): Use AsyncDeutero with asyncio. Every method has the same signature as the sync client.
- [Configuration](https://docs.deutero.ai/get-started/configuration.md): Base URL, timeouts, custom HTTP clients and connection lifecycle.
- [Study lifecycle](https://docs.deutero.ai/guides/study-lifecycle.md): Draft, configure, validate, publish and pause a study.
- [Interview flows](https://docs.deutero.ai/guides/interview-flows.md): Author branching interviews with conditional paths, captured answers, data fetches and signals.
- [Recruitment and embedding](https://docs.deutero.ai/guides/recruitment-and-embedding.md): Share participation links, attribute arrivals to your own users, cap responses, and embed the interview in your site.
- [Simulations](https://docs.deutero.ai/guides/simulations.md): Rehearse a study with AI personas before recruiting real participants.
- [Analyzing responses](https://docs.deutero.ai/guides/analyzing-responses.md): Export transcripts, search what participants said, tally structured answers and cluster free text into themes.
- [Receiving webhooks](https://docs.deutero.ai/guides/receiving-webhooks.md): Subscribe to organization events and verify the signed deliveries Deutero sends you.
- [Error handling](https://docs.deutero.ai/guides/error-handling.md): Catch specific exceptions for API, network and webhook errors.
- [Changelog](https://docs.deutero.ai/changelog.md): Notable changes to the Deutero Python SDK.
- [Deutero and AsyncDeutero](https://docs.deutero.ai/reference/client.md): The client classes, their constructor options and the resources they expose.
- [client.projects](https://docs.deutero.ai/reference/projects.md): Create and manage the projects that group your studies.
- [client.studies](https://docs.deutero.ai/reference/studies.md): Create, configure, draft, validate, publish and pause studies.
- [client.welcome](https://docs.deutero.ai/reference/welcome.md): The welcome and consent message participants see first, and its translations.
- [client.screening](https://docs.deutero.ai/reference/screening.md): Qualifying multiple-choice questions that gate who can take part.
- [client.characteristics](https://docs.deutero.ai/reference/characteristics.md): Participant attributes collected before the interview, for segmenting results.
- [client.questions](https://docs.deutero.ai/reference/questions.md): The linear interview question list: create, generate, edit, reorder and validate.
- [client.graph](https://docs.deutero.ai/reference/graph.md): Branching interview flows: read, write, patch, check, activate and inspect signals.
- [client.recruitment](https://docs.deutero.ai/reference/recruitment.md): Participation links, short-link slugs, response quotas and post-completion redirects.
- [client.embed](https://docs.deutero.ai/reference/embed.md): Publishable keys and install snippets for embedding the interview widget in your site.
- [client.personas](https://docs.deutero.ai/reference/personas.md): AI participant personas used by simulations.
- [client.simulations](https://docs.deutero.ai/reference/simulations.md): Start, list, poll and delete simulated interview runs.
- [client.interviews](https://docs.deutero.ai/reference/interviews.md): Interview records, lookups by your own participant ID, transcripts and flow effects.
- [client.transcripts](https://docs.deutero.ai/reference/transcripts.md): Bulk transcript export and full-text, semantic or hybrid search across answers.
- [client.analysis](https://docs.deutero.ai/reference/analysis.md): Analyzable questions, scale and option tallies, and k-means thematic clustering.
- [client.webhooks](https://docs.deutero.ai/reference/webhooks.md): Manage organization webhook endpoints, signing secrets and the delivery log.
- [client.credits](https://docs.deutero.ai/reference/credits.md): Your organization's credit balance.
