### Filter qualifiers for X Activity API subscriptions

X Activity API subscriptions now accept an optional `filter.qualifiers` map of event-specific predicates that narrow which events match. You can scope `chat.received` events by `conversation_type` (`direct` or `group`), and `follow.follow`, `follow.unfollow`, and `like.create` events by `direction` (`inbound` or `outbound`). A subscription can have up to 8 qualifier entries. See [Filter qualifiers](/x-api/activity/introduction#filter-qualifiers) for details.

### Broadcast start and end events for X Activity API

We added two public event types to the [X Activity API](/x-api/activity/introduction): `broadcast.start` and `broadcast.end`. Subscribe by User ID to be notified in real time when a user starts or ends a live broadcast, using either app-only or user-context authentication. Sample payloads are available on the [event payloads](/x-api/activity/event-payloads) page.

### New credit balance endpoint

We added [`GET /2/usage/credits`](/x-api/usage/get-usage-credits), which returns your Pay-Per-Use credit balance in USD so you can monitor remaining credits programmatically.

### Pay-per-use monthly Post cap raised to 3 million

The monthly [Post read cap](/x-api/fundamentals/post-cap) on pay-per-use plans increased from 2 million to 3 million Posts.

### `is_subscriber` field on `broadcast.chat` events

The `broadcast.chat` event payload in the X Activity API now includes an `is_subscriber` boolean alongside the chat message and author details. See the [event payloads](/x-api/activity/event-payloads) page for an updated sample.
