# Data freshness

> How often each kind of data is recorded, and how to tell how old it is.

Routeur reads the venues on a schedule. Each response tells you what it was built from, so you never have to guess how current it is.

| Data                                     | Recorded                         | How to tell                                                  |
| ---------------------------------------- | -------------------------------- | ------------------------------------------------------------ |
| Kalshi markets and asks                  | Every 15 minutes                 | `observed_at` on each price                                  |
| Polymarket markets and asks              | Every 30 minutes                 | `observed_at` on each price                                  |
| Trades on both venues                    | Every minute                     | `executed_at` on each trade                                  |
| The graph: relations, events, leads      | Hourly, 10 minutes past the hour | `graph_run` on the response; `GET /v1/status` for its timing |
| Unusual flow, moves, one-sided money     | Every 5 minutes                  | `last_detected_at`, `detected_at`                            |
| Settled markets, calibration, strategies | Every 30 minutes                 | `refreshed_at` on calibration                                |

## Checking the service

`GET /v1/status` returns the latest finished graph run, with when it started and finished and the crawls it read, plus the latest crawl of each venue and the latest complete one.

```bash theme={null}
curl https://api.routeur.app/v1/status -H "X-API-Key: $ROUTEUR_API_KEY"
```

<Tip>
  A graph run only reads complete crawls. If a venue's latest crawl did not finish, the graph keeps using the previous complete one, and its markets stay listed rather than disappearing.
</Tip>

## Prices are observations

Prices are the venues' top-of-book asks as recorded, not live quotes. Between recordings the book can move, and a venue can have more size at worse prices behind the top level. For an order, read the venue's book directly; for sizing a lead, use its [`depth`](/concepts/leads#what-a-lead-reports).
