At a glance
Cornerstones is a managed market context layer for AI trading agents. It gives teams one product surface for market truth, chart evidence, event context, and account-aware access without exposing private infrastructure.
What Cornerstones does
Cornerstones packages market information into bounded, verifiable context that agents can use before they write research, compare securities, or prepare a decision handoff.
Current product shape
- Free: starter market truth for basic FX, crypto, stock, A-share, and stock research inputs such as transcripts, analyst estimates, ratings, price targets, ratios, and key metrics where enabled.
- Pro: every Free surface plus charts, context packets, options intelligence, and macro detail.
- Max: every Pro surface plus deeper orderflow, liquidity, depth, tick, and imbalance coverage where enabled.
Stocks and options workflow
Stock workflows start with bounded candidate discovery, then add issuer details, option eligibility, transcripts, analyst estimates, ratings, price targets, ratios, key metrics, earnings, filings, corporate actions, sessions, indicators, and chart context as the account level permits.
Options intelligence belongs in Pro. It covers read-only chain, wall, and analysis views with identity, quote, Greeks, liquidity, open interest, volume, and quality metadata. It does not include trade construction, order submission, risk operations, or reconciliation.
Beta boundaries
Cornerstones public beta keeps availability explicit. Some surfaces are scoped, some higher-intensity reads remain premium, and some responses may include availability or quality notes rather than pretending every deeper surface is available to every account.
