Open Data

Open, de-identified data on mental-health care

Vadia Health publishes aggregate, de-identified statistics about behavioral and mental-health care across the practices on our platform — free to explore through a public API, so researchers, students, and communities can study access and help make care better.

Why we publish it

Data in the service of better mental-health care

Good decisions need good information. By sharing what our platform can measure — how many visits happen, in what languages, in what parts of the country — we hope to support research, teaching, and community efforts to widen access to mental-health care. Everything here is counted across all clinics combined, and nothing identifies a person or a single practice.

What's in the data

The datasets

Eight read-only datasets, each returned as JSON with a meta block describing its license, refresh date, and privacy note. All are served under a single base path.

Base URLhttps://api.vadiahealth.com/api/public/open-data

Dataset	Endpoint	What it shows
Catalog	`/api/public/open-data`	The list of every dataset with its description and metadata.
Platform summary	`/api/public/open-data/summary`	Totals across the platform: participating clinics, active clinics, providers, and completed visits.
Visits by month	`/api/public/open-data/visits-by-month`	Completed-visit volume for each month.
Visits by modality	`/api/public/open-data/modality`	Completed visits split by how care was delivered — in person, telehealth, or phone.
Clinics by region	`/api/public/open-data/clinics-by-region`	Number of clinics in each U.S. state (state level only).
Languages served	`/api/public/open-data/languages`	Languages clinicians offer care in, and how many offer each.
Service categories	`/api/public/open-data/service-categories`	Specialties and service categories offered, and how many clinicians offer each.
No-show rate	`/api/public/open-data/no-show-rate`	Share of finished scheduled visits that ended as no-shows.

How we protect privacy

Built to share numbers, never people

This program is designed so it can never expose a patient, a clinician, or a single clinic. Here is how.

Aggregate and de-identified

Every figure is a total across all clinics and solo practices combined. There are no patient records, no per-clinic rows, and no individual entries — just counts and rates.

HIPAA de-identification standard

De-identification follows the HIPAA de-identification standard (45 C.F.R. § 164.514). No protected health information and no personal data are ever published.

Small groups are hidden

Any cell built from fewer than 11 underlying records is suppressed (k ≥ 11). Small groups are folded into an “other” bucket or left out, so no one can be singled out by a rare combination.

State-level geography only

Location is published at the U.S. state level only. We deliberately never publish county or neighborhood, so the data can't be used to point at a specific clinic.

No re-identification

Using the data to try to re-identify any person, clinician, or clinic is prohibited, and combining it with other sources to do so isn't allowed.

Acceptable use

A few simple rules

You're free to use, analyze, and build on this data. In return we ask that you:

These datasets are governed by our Terms of Service — see section 9 (de-identified and aggregate data) and section 10 (Open-Data API acceptable use).

Give credit — attribute the data to “Vadia Health.”
Never attempt to re-identify a person, clinician, or clinic.
Treat it as informational only — it's provided “as is,” with no warranty, and isn't for clinical or individual decision-making.
Don't imply that Vadia Health endorses you or your work.
Stay within the rate limits — an optional API key is available if you need higher volume.

Getting started

Make your first request

Every endpoint is a plain HTTP GET that returns JSON. No key is required to start — just call it. Higher-volume users can add an optional API key for metering.

Example requests

curl https://api.vadiahealth.com/api/public/open-data
curl https://api.vadiahealth.com/api/public/open-data/summary
curl https://api.vadiahealth.com/api/public/open-data/visits-by-month

Example response

    "completed_visits": 48210
  },
  "meta": {

    "suppression": "Cells with fewer than 11 underlying records are suppressed; k >= 11.",

}

Every response wraps its rows in data and carries a meta block with the dataset id, description, suppression note, refresh date, license, and a link to these Terms.
