# Lighter

Lighter historical data is available since **2026-04-17**.

{% embed url="<https://api.tardis.dev/v1/exchanges/lighter>" %}
See Lighter historical data coverage: available symbols, channels, date ranges and incidents
{% endembed %}

### Downloadable **CSV** files

Historical CSV datasets for the first day of each month are **available to download without API key**. See [downloadable CSV files documentation](/downloadable-csv-files/overview.md).

{% hint style="info" %}
Lighter data collection started after the April 2026 monthly sample date. Public monthly sample links will be available from the next first-day dataset.
{% endhint %}

### API Access and data format

Historical data format is the same as provided by real-time Lighter WebSocket API with addition of local timestamps. Lighter symbols in Tardis.dev APIs are numeric market ids, for example `1` for a perpetual market and `2048` for a spot market. If you'd like to work with **normalized data format** instead (same format for each exchange) see [downloadable CSV files](/downloadable-csv-files/overview.md) or official [client libs](/api/quickstart.md) that can perform data normalization client-side.

{% tab title="Python" %}

```python
# pip install tardis-dev
import asyncio
from tardis_dev import Channel, replay

async def main():
    async for local_timestamp, message in replay(
        exchange="lighter",
        from_date="2026-04-17",
        to_date="2026-04-18",
        filters=[Channel(name="order_book", symbols=["1"])],
        api_key="YOUR_API_KEY",
    ):
        # messages as provided by Lighter real-time stream
        print(message)

asyncio.run(main())
```

See [Python client docs](/python-client/quickstart.md).
{% endtab %}

{% tab title="Node.js" %}

```javascript
// npm install tardis-dev
import { replay } from 'tardis-dev';

const messages = replay({
  exchange: 'lighter',
  from: '2026-04-17',
  to: '2026-04-18',
  filters: [{ channel: 'order_book', symbols: ['1'] }],
  apiKey: 'YOUR_API_KEY'
});

// messages as provided by Lighter real-time stream
for await (const { localTimestamp, message } of messages) {
  console.log(localTimestamp, message);
}
```

See [Node.js client docs](/node-client/quickstart.md).

```

{% tab title="cURL & tardis-machine" %}

```bash

```

[Tardis-machine](/tardis-machine/quickstart.md) is a locally runnable server that exposes API allowing efficiently requesting historical market data for whole time periods in contrast to [HTTP API](/api/http-api-reference.md) that provides data only in minute by minute slices.

See [tardis-machine](/tardis-machine/quickstart.md) docs.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tardis.dev/historical-data-details/lighter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
