<Warning>
  As part of our migration to DIA's next-generation oracle infrastructure, Lumina, the hosted DIA REST API is being deprecated and will be discontinued on **20 December 2026**. This affects the REST endpoints under `https://api.diadata.org/v1`.

  If your protocol relies on these, please email [support@diadata.org](mailto:support@diadata.org) and confirm that you are using them. We will provide you with a migration path so you can continue accessing the same data through Lumina without interruption. Integrations that don't reach out may lose access after the deprecation date.
</Warning>
