Dmand AI is a public enrichment API built for healthcare go-to-market teams. Its current capability resolves 10-digit NPI numbers to verified, deliverable emails for individual healthcare providers (HCP, NPI Type 1). Submit a request asynchronously and receive results by polling or webhook.

What the API does today

The Dmand AI API currently supports NPI to email enrichment for healthcare providers (HCP, NPI Type 1). Given a 10-digit NPI number, the API returns a verified email address if one is found. Executive enrichment and non-NPI lookups are not yet supported.

How it works

1

Submit an NPI

Send a 10-digit NPI to POST /api/v1/email (single) or POST /api/v1/email/bulk (up to 100 NPIs).
2

Receive an ID

The API returns HTTP 202 with a batch_id and per-NPI request_id values.
3

Get results

Poll GET /api/v1/email/{request_id} or GET /api/v1/batch/{batch_id}, or receive a webhook on the configured URL.
4

Read the email

When status is completed, the data array item contains the verified email and related fields.
Base URL: https://ext-api.dmand.ai. All public paths are under /api/v1. Emails are only returned if validated within the last 30 days. Older emails are re-verified or re-enriched live, which can take up to about 15 minutes. If a request cannot finish within 15 minutes, it is marked failed and its credits are refunded.
