## Routing Guidance

### General crypto questions
Route through **AI** first — broadest context, synthesizes across market data, research, news, social.

### Quantitative questions
Use **Metrics** for price/volume/fundamentals. **Exchanges** for exchange-level data. **Networks** for L1/L2 metrics. **Protocols** for DeFi-specific data.

### Sentiment and narratives
**Signal** for mindshare and sentiment. **Topics** for trending narrative classes. **X-Users** for influencer-level metrics.

### Specific asset classes
**Stablecoins** for stablecoin supply and flows. **Token Unlocks** for vesting schedules and upcoming unlocks.

### Research, news, and events
**Research** for deep dives and reports. **News** for real-time events. **Intel** for governance and protocol updates. **Fundraising** for funding rounds and M&A.

### Multi-service queries
Combine services for richer answers. Example — "Is SOL overvalued?":
1. **Metrics** → current price, volume, fundamentals
2. **Signal** → sentiment and mindshare trend
3. **Token Unlocks** → upcoming supply pressure
4. **AI** → synthesize a view from all data
