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
