The default path is **submit audio → analyze → get results**, using the wellness model (`pulse`). Other models are available. Walk through it once in the [Quickstart](/guides/quickstart).

## Submit, analyze, get results

**Submit.** On the analyze request, send the file as multipart `audio`. Formats, size, and quality codes: [Audio Requirements](/guides/audio-requirements). If the bytes should not ride on that request, mint a PUT URL first — [Audio Uploads](/reference/audio).

**Analyze.** `POST /v2/models/pulse/analyze` returns a job immediately (`status: queued`, `result: null`) — [Model API](/reference/models). Other bundles: [Choosing a Model or Sign](/guides/choosing-a-model-or-sign).

**Get results.** Poll `GET /v2/jobs/{job_id}` or use a [webhook](/guides/jobs#webhooks) until `status` is `done`. On a model job, route on `result.summary.recommended_action` — [Interpreting Results](/guides/interpreting-results).

## As-is

All models and API outputs are provided **as-is**. Labels such as **Established**, **Emerging**, and **Investigational** describe published research depth, not a commercial tier. See [Sign Catalog — evidence tiers](/catalogs/signs#evidence-tiers). Outputs are biomarker signals, not diagnoses.

## Advanced

- **[Specific sign analysis](/reference/signs)** — Result for one health sign from the recording.
- **[Longitudinal analysis](/guides/longitudinal)** — Analysis that takes the person's past results into account.
- **[Group-based analysis](/guides/longitudinal#cohort-aggregates)** — Group-level or population-level aggregate analysis.

- [API Reference](/reference) — base URL, auth, rate limits, endpoint map.
- [Production Checklist](/guides/production) — ship against this API.
