+    title: D1 will begin enforcing its free tier limits from ?? ??, 2025.
+    description: |-
+      Previously, D1 did not enforce the free tier limits as set out in the [D1 limits documentation](/d1/platform/limits). D1 will begin enforcing the daily free tier limits from ??/??/2025.
+
+      From ??/??/??, if you do not take any action and exceed the daily free tier limits, queries to D1 databases via the Workers API and/or REST API will return errors until limits reset daily at 00:00 UTC.
+
+      To ensure uninterrupted service, upgrade your account to the Workers Paid plan from the [plans page](https://dash.cloudflare.com/?account=/workers/plans). The minimum monthly billing amount is $5 and includes 25 billion rows read and 50 million rows written per month. [Billing metrics](/d1/observability/billing/) for rows read and rows written can be found on the [D1 dashboard](https://dash.cloudflare.com/?account=/workers/d1) or GraphQL API.
