First & Last Response Timestamps in LLM Mentions API

Today we’re bringing you smoother analytics experience in the LLM Mentions API with two new timestamp fields that help you understand exactly when mention-containing LLM responses were first and last recorded in our database.

What’s new

The Search Mentions endpoint now includes two additional fields for each object in the items array:

  • first_response_at — date and time when the response data was first recorded.
  • last_response_at — date and time when the data was most recently updated.

These fields are also available in the list of filters for LLM Mentions API, so you can now use them to filter mentions when setting tasks to:

Simply indicate the necessary field and value inside the initial_dataset_filters parameter in the UTC format: “yyyy-mm-dd hh-mm-ss +00:00”. To learn more about filtering operators that work with time fields, check our docs.

Get started

Refer to the updated LLM Mentions API documentation to start using time-based filtering and analytics in your AI Optimization workflows.
