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?":
- Metrics → current price, volume, fundamentals
- Signal → sentiment and mindshare trend
- Token Unlocks → upcoming supply pressure
- AI → synthesize a view from all data
