> ## Agent Instructions
> To integrate AGG, start with Quickstart: REST (https://docs.agg.market/quickstart/rest), then Order lifecycle & statuses (https://docs.agg.market/concepts/order-lifecycle).
> Track every trade until it reaches a terminal status. Before retrying a failed or timed-out call, read Errors, retries & idempotency (https://docs.agg.market/concepts/errors).
> The API reference is generated from https://docs.agg.market/openapi/openapi.json.

# Get versioned chart history references

> Returns at most eight authorized CDN chunks, effective resolution, finalization boundary and delivery state. Fetch the unfinished tail with /charts/bars.

## Integration guide

* **Before you call:** [Choose market-data reads and handle their limits](/api/market-data).
* **Workflow:** [Load chart history and the live tail](/recipes/websocket-charts).
* **Next:** [Build an event and market screen](/recipes/building-market-views).
