Every plan below is an entitlement tier attached to a Web of Science, InCites or product subscription, and the published numbers are request allowances, not prices — the portal states plainly that "the plans are not visible during the subscription process" for the Expanded API and that Clarivate configures the tier from the institution's contract. The one plan anyone can obtain without a subscription is the Web of Science Starter API Free Trial Plan at 50 requests/day. This file replaces a 2026-05-04 scaffold that invented Free / Professional / Enterprise tiers with 1,000 and 100,000 request quotas; none of those values existed at Clarivate. pricing_model: subscription-entitlement currency: null public_price_list: false plan_count: 13 plans: - id: wos-starter-free-trial name: Free Trial Plan api: Web of Science Starter API type: freemium price: null description: >- Available to anyone, even if your organization does not subscribe to Web of Science.
