Live read. Asks Meta now for the Meta Pixels of one ad account. An ad set that optimizes for a conversion names one: send its `id` as `pixelId` when you create an ad set.

`lastFiredTime` tells which Pixel receives events. A Pixel that never received an event is usually not installed. When no page holds a Pixel, up to the page with no `nextCursor`, the ad account has no Pixel.

An advertiser that your organization does not own answers `404`, with `error` of `not_found`. An advertiser that does not exist, and one that is not a Meta ad account, answer the same.

AdCrunch stores nothing from this read. Each request counts against the rate limits of Meta.

`limit` and `cursor` page the answer. Send `nextCursor` back as `cursor` to get the next page. A page can hold no row and still carry `nextCursor`.
