# api.x402.printmoneylab.com

This host serves agents that need to classify or vet a wallet address before taking action — for example, before processing a payment, extending credit, or personalizing a response. It provides a labeled profile derived from aggregated on-chain history, making it useful for risk assessment, fraud screening, or user segmentation workflows. It is a single-resource host with no trading, pricing, or streaming capabilities.

## When to use this host

Use this host when an agent needs to classify a wallet address — retrieving a label, confidence score, and transaction history summary — prior to making a decision such as payment processing or access control. Do not use it for real-time or streaming wallet monitoring; it returns a single historical snapshot per request. It is not suitable for price feeds, trade execution, token analytics, or any task unrelated to wallet identity and history. If live transaction tracking is needed, a dedicated blockchain indexer or streaming analytics service would be more appropriate.
