The AtomicDEX-API stores historical information such as swaps and orders within an SQLite database, located under the DB user data folder (e.g. {folder continaing mm2 binary}/DB/{wallet identifying hex string}/MM2.db).

There are a variety of methods to query sqlite databases. Examples below show how to do a sqlite query in Linux terminal, but first you might need to install sqlite with sudo apt install sqlite3.

The tables and columns available to query are as follows:

# my_swaps

0 id INTEGER Primary Key
1 my_coin VARCHAR(255) Coin sent

3 uuid VARCHAR(255) Swap UUID
4 started_at INTEGER Timestamp

# Query:

sqlite3 ${PATH_TO_MM2_DB_FILE} "SELECT * FROM my_swaps WHERE id=2 LIMIT 1"

# Response:
