Developers
What you can call, and how current it is.
As of 13 November 2026. The states in this release, a snapshot of what landed, and the timestamp on each field.
This release
Queryable states.
A search for any other state returns no rows. That is the edge of the release. The product is built for the rest of the country, and a state is named here only after it is queryable. Examples elsewhere on this site use fictional records. Pass one of these codes when you call the API. The same note is at transparency.json.
Montana
Nevada
New Jersey
New Mexico
Utah
Vermont
Wyoming
Status
Latest changes.
What had landed when this page was published. A payer is named in a state when that network is part of the release there. A few clinicians outside that footprint are left off the row. Payer files feed the pipeline. The practice API does not return them as their own object. Cadence for the wider method is on coverage.

Surfaces
What a record is made of.
These are the surfaces a caller can reason about on a practice record.
| Surface | Cadence | What you can read |
|---|---|---|
| Practice directory | Weekly | Location, clinicians, address, and specialty from the NPI registry. |
| Medicare clinician data | Monthly | Specialty and practice-address clues, folded into the same record. |
| Practice website | When the page changes | Published phone, team, services, and contacts, after the identity check. |
Freshness
The timestamp is on the field.
Pass expand=evidence on a location. Each field can open into a value, a status, a source URL, a quote, and observed_at.
observed_at is when we read the source behind that value. Each field has its own. Status is verified, observed, or candidate. An empty field has no timestamp.
The dictionary defines the object under evidence. The call is the same one on the API page.
curl "https://api.practicemcp.com/v1/practices?state=NJ&limit=1" \
-H "Authorization: Bearer $PRACTICEMCP_API_KEY"curl "https://api.practicemcp.com/v1/practices/{id}?expand=evidence" \
-H "Authorization: Bearer $PRACTICEMCP_API_KEY"Scope
Left off on purpose.
A developer needs the release boundary and the timestamp on a field. The warehouse stays internal.
- Counts of practices, clinicians, or rows.
- A coverage percentage for websites or contacts.
- File names and per-file row counts.
- A live job log. The table on this page is a snapshot from the last deploy.
Read one record with the timestamp open.
Get a key, fetch a location in a state on this page, and add expand=evidence.
