freshprobe
Data freshness verification for AI agents.
Stop your agents from acting on stale data.
"I asked my agent to check flight prices. It gave me options. I booked one. The fare had changed 3 hours ago."
AI agents routinely act on stale data without knowing it. A financial agent queries cached quotes from 47 minutes ago. A support bot tells a customer their order doesn't exist because the CRM hasn't synced. An RAG pipeline confidently answers with yesterday's docs.
freshprobe sits between your agent and the external world. Before the agent acts, it asks: is this data fresh enough? The answer is always a deterministic JSON verdict: FRESH, STALE, or UNKNOWN.
