ROOK API Pricing (tryrook.io): Plans, Active Users and Add-ons

What ROOK charges#

ROOK's pricing page says "ROOK pricing is based on the plan and the number of active users, with usage-based billing and the flexibility to activate only the products and add-ons needed." As we read it on November 4, 2026:

The page marks Business "Most popular". Past a plan's ceiling, "billing adjusts based on usage", and "The sales team shares the details at the time of contracting." Every page on this site about ROOK is collected in the ROOK API overview.

Products and add-ons by plan#

The Wearable API and the Medical Device API are included on every plan; the EHR/EMR API is a waitlist item. The rest is priced per month on Core:

The callback URL, pre-existing data and medical-device metadata are included on every plan. Branded Auth is marked "On hold". On Core+, "the listed price applies from the fourth on".

Lab Data API, billed by files#

"Lab Data API is billed by the files processed each month, on every plan." Starter is $249 a month for up to 300 files and Growth $299 for up to 750; six more tiers run from $349 up to $1,299 for up to 20,000 files a month, and above that the price is custom.

Our arithmetic#

Our calculations from the list prices, not a quote from ROOK:

• Price per active user at each ceiling. Core is about $0.53 a user at 750, Core+ about $0.20 at 5,000, and Business about $0.13 at 15,000.
• Core+ can be cheaper than Core below 750 users. Core with three $249 add-ons costs $1,146 a month ($399 plus $747); Core+ costs $999 with three add-ons included. With two $249 add-ons, Core ($897) is still cheaper.
• Between ceilings you pay for the next plan. At 751 to 5,000 active users the list price is Core+, $999, unless ROOK's unpublished usage rate past Core's ceiling comes to less.

Contract, payment and trial#

• Term. "ROOK's standard contract term is 12 months, with the flexibility to cancel with 30 days' prior notice."
• Trial. ROOK "provides Sandbox access to test the portal and integration before enabling Production". Production "requires an active plan and execution of the applicable agreements."
• Payment. "ROOK accepts card payments through Stripe"; bank transfer is confirmed per agreement.
• Startups. "Entry plans, discounts, and startup programs can change over time", so ask ROOK's sales team.
• BAA. ROOK signs one "when the customer is a Covered Entity or Business Associate and a BAA applies to the relationship", with eligibility reviewed during contracting. Its compliance page says it "signs BAAs with covered entities" and processes EU personal data under GDPR as a data processor. This is general information, not legal advice; see HIPAA for fitness apps.

What the plans connect to#

ROOK's data-sources page says it covers "over 400 health data sources and wearable devices", through direct APIs for cloud providers such as Fitbit, Garmin, Oura, Polar and Withings, and through SDKs for Apple Health and Health Connect. For four providers there is a cost in time rather than money: its docs say clients must create their own developer accounts with Dexcom, Samsung Health, Strava and WHOOP, a process that "can take several weeks".

Evaluating ROOK on price#

If ROOK's plans are the ones you are pricing, check four things against your own product:

• Your active-user count a year out. The contract is 12 months, so price the plan you will be on, not the one you start on.
• The add-ons you need. Count them: three or more on Core is where Core+ wins.
• Lab report volume. The Lab Data API is billed by files on every plan, so model your files a month separately.
• Your own developer accounts. Dexcom, Samsung Health, Strava and WHOOP need them; start those applications early.

For ROOK's data model, delivery and normalization, see the evaluation section of Terra vs ROOK.

How it compares#

At list price on November 4, 2026, ROOK's Core at $399 for 750 active users matches Terra's $399 annual entry price, which includes 100,000 credits, enough for 500 connected sources at 200 credits each. Junction's Launch is a flat $300 a month for up to 500 connected users, and Sahha's Starter $299 a month billed annually with 1,000 users included. By our arithmetic ROOK stays flat longer than Terra: at 5,000 users with one source each, Core+ is $999 against about $4,899 on Terra. See Terra API pricing, Junction API pricing, the side-by-side aggregator pricing, and ROOK alternatives if ROOK does not fit.

What we could not verify#

• The usage rate past each plan's active-user limit; ROOK shares it at contracting.
• How ROOK defines an active user for billing; the pricing page uses the term without defining it.
• The prices of the six middle Lab Data API tiers, which the page summarizes as "From $349 USD / month".
