Cornerstones client guide for agent onboarding

At a glance

The public client is the onboarding path for agent workflows, but this website page keeps the explanation at the product level. Detailed command recipes belong in the client help and operator materials, not in customer-facing plan pages.

Start with discovery

Free starts with public discovery and selected basic market reads. Durable account access uses a Cornerstones-issued key and follows the same Free, Pro, or Max boundaries shown in Billing.

Plan boundaries

• Free: starter market truth and stock research inputs such as transcripts, analyst estimates, ratings, price targets, ratios, and key metrics where enabled.
• Pro: charts, context packets, options intelligence, and macro detail.
• Max: deeper orderflow, liquidity, depth, tick, imbalance, raw, summary, context, and historical reads where enabled.

Onboarding truth

Cornerstones keys are product keys for market context. They are not broker, exchange, model-provider, or upstream data-provider credentials.
