See the bottom of the post: "We charge per full medical record retrieval for a patient (which we call a query). This starts at $1 per query (with a monthly minimum), and scales down from there based on volume. We only charge for queries that return at least one record (and even if a query returns 1000 documents for a single patient, we still count that as a single query) - no charge is incurred for sharing data back to the networks, or making API calls to generate medical record summaries, for example."
