# 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.
