- Fetch Unconfirmed Transactions (HTTP Request): calls blockchain.info
- Extract Bitcoin Transactions (Code): runs custom JavaScript code
- Filter Clean Transactions (Code): runs custom JavaScript code
- Process Clean Transactions (Code): runs custom JavaScript code
- Limit: keeps the first few items
- Filter: keeps only the items that match a condition
- Analyze Transactions with LLM (Basic LLM Chain): sends a prompt to an LLM, with model: Groq Transaction Chat Model
- Append to Bitcoin AML Sheet (Google Sheets): append
Services it uses
HTTP calls to: blockchain.info
