# Timeframes and Resolutions

> Which time buckets each data family supports, and what the daily-only metrics mean.

The `timeframe` parameter selects the aggregation bucket. Endpoints that do not accept it
are daily by construction — most on-chain, macro and sentiment metrics are computed once a
day and have no intraday form.

| Data family          | Timeframes                                              | Assets |
| -------------------- | ------------------------------------------------------- | -----: |
| `screener`           | `1d`                                                    |    772 |
| `macro`              | `1d`                                                    |    568 |
| `crypto_ohlcv`       | `12h`, `15m`, `1d`, `1h`, `1m`, `30m`, `4h`, `5m`, `6h` |    210 |
| `liquidation_levels` | `12h`, `15m`, `1d`, `1h`, `1m`, `30m`, `4h`, `5m`, `6h` |    206 |
| `open_interest`      | `12h`, `15m`, `1d`, `1h`, `1m`, `30m`, `4h`, `5m`, `6h` |    206 |
| `exchanges_metrics`  | `12h`, `15m`, `1d`, `1h`, `30m`, `4h`, `6h`, `raw`      |    204 |
| `onchain`            | `1d`                                                    |    132 |
| `sentiment`          | `1d`                                                    |    128 |

`raw` (derivatives metrics) is the exchange's own publishing interval, stored without
resampling. It is a storage resolution, not a value you can pass in `timeframe`.

## Values the parameter accepts

`1m`, `5m`, `15m`, `30m`, `1h`, `4h`, `6h`, `12h`, `1d` — matched case-insensitively.

**An unrecognised value does not fail.** The request falls back to the daily series, so a
typo returns valid-looking data at the wrong resolution. Each endpoint page lists the
timeframes that endpoint actually carries.

## Rules that hold across the API

* Timestamps are **UTC**, ISO-8601.
* Series come back in **ascending** chronological order.
