See [downloadable CSV files documentation](/downloadable-csv-files/overview.md). {% hint style="info" %} Star Atlas DEX symbols are Solana market addresses (e.g., `AYXTVTTPFHYMN3JRYX5XBRJWPK2M9445MBN2ILYRD6NQ`). See the [exchange metadata endpoint](https://api.tardis.dev/v1/exchanges/star-atlas) for full symbol list. {% endhint %} | data type | symbol | date | | | --------------------- | ----------- | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | | incremental\_book\_L2 | AYXT...D6NQ | 2022-01-01 | [Download sample](https://datasets.tardis.dev/v1/star-atlas/incremental_book_L2/2022/01/01/AYXTVTTPFHYMN3JRYX5XBRJWPK2M9445MBN2ILYRD6NQ.csv.gz) | | quotes | AYXT...D6NQ | 2022-01-01 | [Download sample](https://datasets.tardis.dev/v1/star-atlas/quotes/2022/01/01/AYXTVTTPFHYMN3JRYX5XBRJWPK2M9445MBN2ILYRD6NQ.csv.gz) | | book\_ticker | AYXT...D6NQ | 2022-01-01 | [Download sample](https://datasets.tardis.dev/v1/star-atlas/book_ticker/2022/01/01/AYXTVTTPFHYMN3JRYX5XBRJWPK2M9445MBN2ILYRD6NQ.csv.gz) | ### API Access and data format Historical data format is the same as provided by real-time Star Atlas DEX WebSocket API (via [serum-vial](https://github.com/tardis-dev/serum-vial)) with addition of local timestamps. 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. {% tabs %} {% 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="star-atlas", from_date="2022-01-01", to_date="2022-01-02", filters=[Channel(name="l2snapshot", symbols=[])], api_key="YOUR_API_KEY", ): # messages as provided by Star Atlas DEX 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: 'star-atlas', from: '2022-01-01', to: '2022-01-02', filters: [{ channel: 'l2snapshot', symbols: [] }], apiKey: 'YOUR_API_KEY' }); // messages as provided by Star Atlas DEX real-time stream for await (const { localTimestamp, message } of messages) { console.log(localTimestamp, message); } ``` See [Node.js client docs](/node-client/quickstart.md). {% endtab %} {% tab title="cURL & HTTP API" %} ```bash curl --compressed -g 'https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01&filters=[{"channel":"l2snapshot","symbols":[]}]&offset=0' ``` {% embed url="" %} Example API response for Star Atlas DEX historical market data request {% endembed %} See [HTTP API docs](/api/http-api-reference.md). {% endtab %} {% tab title="cURL & tardis-machine" %} ```bash curl -g 'localhost:8000/replay?options={"exchange":"star-atlas","filters":[{"channel":"l2snapshot","symbols":[]}],"from":"2022-01-01","to":"2022-01-02"}' ``` [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. {% endtab %} {% endtabs %} ### Captured real-time channels {% embed url="" %} See serum-vial docs providing documentation for each captured channel's format {% endembed %} {% hint style="info" %} Click any channel below to see [HTTP API](/api/http-api-reference.md#data-feeds-exchange) response with historical data recorded for it. {% endhint %} * [trade](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22trade%22}]) Public trade executions stream * [l2snapshot](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22l2snapshot%22}]) Level 2 order book snapshots * [l2update](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22l2update%22}]) Level 2 order book incremental updates * [quote](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22quote%22}]) Best bid and ask quote updates * [recent\_trades](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22recent_trades%22}]) Recent trades snapshot stream * [l3snapshot](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22l3snapshot%22}]) Level 3 order book snapshots * [open](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22open%22}]) Order open events * [fill](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22fill%22}]) Order fill events * [change](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22change%22}]) Order change events * [done](https://api.tardis.dev/v1/data-feeds/star-atlas?from=2022-01-01\&filters=\[{%22channel%22:%22done%22}]) Order done events ### Market data collection details [Market data collection infrastructure](/faq/general.md#what-is-your-infrastructure-setup) for Star Atlas DEX was located in GCP europe-west2 region (London, UK). Real-time market data was captured via **WebSocket connection** to `wss://serum-vial.tardis.staratlas.one/v1/ws`. {% hint style="info" %} Star Atlas DEX was a Solana-based decentralized exchange with no centralized server infrastructure. {% endhint %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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/star-atlas.md?ask=&goal= ``` `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.
