SNOW Docs

Turn patient history into structured actionable summaries. One API key, four integration flows, real-time webhooks.

What SNOW does

SNOW takes a combination of patient questions, uploaded reports, and pre-collected structured data, and returns a clinician-grade structured summary. Use it for pre-visit forms, emergency triage, discharge handoffs, and other clinical workflows.

Pre-visit summarization

Patient gets a WhatsApp link, fills the form, doctor sees the summary. Single-submit or iterative, with or without uploads. Recipe →

Direct-mode summarization

Your backend already has the data — POST it, get a summary. No patient UI needed. Perfect for emergency triage from in-app red-flag detection.

Hosted patient form

SNOW hosts the patient-facing form on previsit.summary.to. You don’t write any UI. Voice, uploads, multi-language all built in.

Real-time webhooks

Configure once. Receive session.completed, intake_session.completed, and other events with HMAC-signed delivery + retry sweep.

The four integration flows

#	Flow	When
1	Hosted form, fixed questions, single-submit	WhatsApp pre-visit form, no uploads
2	Hosted form, full UX (questions + uploads + voice)	Pre-visit with prior reports
3	Direct API — you POST what you have	Your backend has the data; no patient UI
4	Hosted form, LLM-driven dynamic questions	Doctor-driven deep-dive

Available summary types

Live types have a validated output schema, full token budget, and golden-fixture tests — safe to build production integrations against. Beta types run the same pipeline but without a structured output schema or regression tests yet; treat output shape as provisional and verify the response before an integration goes live.

Type	Status	Recipe
`pre-consult` (`pre-anc-visit`, `pre-visit-clinic`)	✅ Live	pre-consult
`emergency` (`emergency-summary`)	✅ Live	coming soon
`clinical-note`	✅ Live	coming soon
`discharge`	✅ Live	coming soon
`medication`	✅ Live	coming soon
`history`	✅ Live	coming soon
`international`	✅ Live	coming soon

patient-instructions is not a /v1/sessions type — it’s a separate endpoint, POST /v1/patient-instructions, that runs synchronously against data you already have.
