FAQ
Use Zerion API and call the /wallets/address/positions/ endpoint to retrieve a full list of positions for any wallet address. If you just want to see assets on Somnia, use the chain filter. Alternatively, you can fetch positions from all chains.
If in-game assets are tokens, you can query Zerion API's /wallets/address/positions/ to see every position held by a wallet address. The response will include token price and other data.
You can set up a webhook to receive alerts whenever a new transaction appears on a Somnia address.
