# Data boundaries by market

One format, different sources: what each market gives and what it lacks.

## Markets compared

| [USA · Copart, IAAI](https://apiauto.space/en/copart-iaai-api/) | every hour | yes | many | past auctions; body type on some lots |

## Copy freshness

The age of the market copy comes in the X-Data-Age-Seconds header of every catalog answer. The current freshness of every market is in [/v1/references/markets](https://apiauto.space/en/docs/endpoints/references/): data_age_seconds and stale.
