# trustscore.dev

trustscore.dev is a point-in-time fraud and trust scoring service targeting agents that need a quick, structured risk verdict before taking action on an unknown entity. It covers three distinct domains—telecom fraud (spam/VoIP/robocall detection), crypto token risk (rugpull/honeypot analysis), and real estate deed fraud—under a single unified API surface. It is not a monitoring platform or a bulk data pipeline; it is designed for single-shot lookups at decision points.

## When to use this host

Use trustscore.dev when an agent needs a fast, structured risk verdict on a single phone number, crypto token, or property address before onboarding a user, executing a transaction, or flagging an entity for review. It is appropriate for pre-action checks where a plain-English summary and discrete risk flags are sufficient. Do not use it for continuous or real-time fraud monitoring, streaming event pipelines, or bulk scoring of large lists—those use cases require a dedicated fraud platform with batch and streaming APIs. It also does not provide identity resolution, KYC document verification, or on-chain transaction history; route those needs to specialized identity or blockchain analytics providers.
