Can no-login users try anything?
Yes. First-touch discovery can start with public guide and changelog flows, while durable authenticated reads use dashboard-issued access.
Agent-native market data
How can AI agents access market data without hardcoded keys?
Put Cornerstones between the agent and private data infrastructure. The agent receives product-level market context, plan-aware limits, freshness signals, and revocable account access instead of raw upstream keys.
Question
How can an AI agent fetch market context without storing raw market-data secrets in prompts, repos, or local config?
When this problem happens
- Agent prompts and tool logs can accidentally retain copied secrets.
- Hardcoded keys are hard to revoke per workflow, per teammate, or per automation lane.
- Market context must show entitlement and freshness without describing private backend infrastructure.
Recommended architecture
Keep sensitive provider credentials server-side, expose only Cornerstones account access to agents, and make every response carry enough plan and freshness context for safe automation.
Implementation steps
- Install the public client and let the agent discover available market surfaces first.
- Issue account-level Cornerstones access instead of copying upstream credentials into agent config.
- Keep quota, plan, and revocation decisions in the dashboard rather than in prompt text.
- Upgrade to Pro or Max only when the workflow needs charts, context packets, options, macro, or deeper liquidity surfaces.
Example workflow
python -m pip install cornerstones-client

| Option | Best for | Tradeoff |
|---|---|---|
| Cornerstones | Agent-native market context | Requires adopting a product-level access model |
| Raw private integration | Human-operated internal systems | Can expose credentials, adapters, and unstable implementation details to agents |
| Static prompt paste | One-off prototypes | No freshness, usage accounting, entitlement boundary, or repeatable evidence trail |
FAQ
Should agents ever see upstream credentials?
No. Agents should receive product-scoped Cornerstones access, not raw private provider or broker credentials.
How do teams revoke a workflow?
Revoke or rotate the product-level key in the dashboard instead of hunting through prompts, repos, and local shell histories.
When is paid access needed?
Use paid plans when workflows need premium charts, options context, macro exact series, orderflow, or liquidity depth.
