# ReachRich

A multi-market quantitative **data platform**. It turns the most tedious part of quant — finding, cleaning, and reconciling data — into one stable service: **unified schema, consistent price adjustment, multi-source cross-validation, real-time and historical from the same source**, with built-in freshness and quality monitoring.

## Why it matters

| Pain | How ReachRich handles it |
|---|---|
| Inconsistent multi-source schema | One unified data contract |
| Adjustment chaos / fake overnight gaps | Consistent corporate-action handling |
| Separate real-time vs history | Same source, same schema |
| Single-source unreliability | Cross-validation + auto failover |
| Unknown data freshness | Per-stream freshness monitoring |

## Relationship to RR-Agent

ReachRich is the **data layer (callee)**. The upper-layer quant research agent **RR-Agent** (separate project) calls it via API / MCP to fetch data. Responsibilities are separated; the two evolve independently.
