How AI agents should read market data responses
Customer guide
At a glance
Every Cornerstones response should be treated as market evidence with account context. The customer-facing rule is simple: check source, freshness, quality, and whether the account is allowed to use the requested surface.
What to inspect
- Source labels and provenance.
- Freshness and timestamp information.
- Data quality notes.
- Availability or account-access state.
- Symbol and market normalization when present.
How to handle unavailable surfaces
Unavailable data is a product boundary, not a reason to invent a result. Agents should use the allowed market context for the current account and clearly state when a premium surface was not included.
