Signal → trade and query volume measured —. Unavailable measurements are shown as —.
Price is the last variable to reflect a change in market state. Volume, hourly activity, and weighted momentum move measurably earlier — but only if something is computing them continuously. Each definition below is a signal the agent recomputes every 30 minutes. Read: self-custody vs custodial AI trading agents →
VOLUME_ANOMALY = today's 24h volume ÷ trailing 7d average
TOKEN_PRICE_MOMENTUM = weighted 24h + 7d price change
Cross-source divergence: Hyperliquid vs CoinGecko · 0.1% avg spread
Everything is keyed to assets, tokens, and protocols. Every endpoint is callable on its own. Prices are per call in USDC or USDT via x402 — no subscription.

Representative calls from the catalog. Every response includes a freshness timestamp. Every predictive call includes a 90-day rolling hit-rate.
Four buyer types, four different decision problems. The catalog has the data each one needs, callable individually.
Predictive signals need a verifiable track record to size against. Smart-money flow needs to be sourced — not inferred from price — to confirm a thesis before a desk commits.
Every predictive call returns a 90-day rolling hit-rate and sample size. Smart-money flow is wallet-level, labeled, and sourced. Deep Research generates against live data on demand.
P/S and P/E ratios require current revenue and fee data. Token unlock impact is a forward supply pressure calculation — not visible from price history alone.
Protocol Financials returns revenue, fees, TVL, and derived ratios. Token Unlocks returns the vesting schedule and an impact forecast. Governance tracks active proposals across protocols.
An agent that needs data at execution time cannot pause for an OAuth flow or manage a rotating API key. The payment must be atomic and the response must be immediately actionable.
x402: the agent calls a tool, reads the price from the 402 response, pays USDC or USDT on Base, and gets data in the same round trip. Over the MCP server: no account, no API key, no session state.
Institutional terminals cost $30,000–$150,000 a year. Most individual traders use a fraction of that data. A single metric should cost a cent; the full catalog should not require a sales call.
Asset Metrics at $0.01 per call. Alerts at $0.02 per fire. AI Copilot at $0.10 per query. Plus includes alerts and watchlists for $15 a month. Fexr Desk brings the full catalog into an organizational workspace for $2,500 a year, with unlimited reports within fair use.
Every analytical challenge has a measurable proxy. Each entry below maps a question that arises in practice to the catalog endpoint that answers it.
Volume expansion and momentum shifts precede price confirmation. By the time the candle is visible, the entry is late.
VOLUME_ANOMALY returns the ratio of current 24h volume to the 7d average. PREDICTIVE_SIGNALS returns a forward call with horizon and drivers.
A vesting event changes the float. The magnitude depends on who holds the vesting tokens, how long they've held them, and whether smart money is already distributing.
TOKEN_UNLOCKS returns the schedule and an impact forecast. SMART_MONEY_FLOW shows whether labeled wallets are accumulating or distributing into the event.
A research thesis built on data from last week may not survive this week's on-chain activity. Protocol revenue, developer commits, and governance votes all change.
AI_COPILOT answers any question against live data, fully cited. DEEP_RESEARCH produces a long-form, sourced report on demand.
A governance vote that passes can alter token economics, fee structures, or treasury allocations. Positions can be material before the vote outcome is reflected in price.
GOVERNANCE returns active and passed proposals, outcomes, and voting data across protocols. WHALE_ALERTS flags large wallet activity near proposal deadlines.
Price and volume signals are observable by anyone. Wallet-level flow from identifiable funded addresses is not — it is a leading indicator that runs ahead of price.
SMART_MONEY_FLOW returns labeled-wallet inflows and outflows. SENTIMENT returns the narrative attention score and social momentum alongside the flow data.
The three gaps below don't exist on any of the eight competing platforms we evaluated.
Prices are sourced from both Hyperliquid and CoinGecko simultaneously. Every signal is built on a price that has already passed a second opinion — 0.1% average divergence across all assets.
Every query returns a live Grade A quality score alongside the signal values. You know the confidence level of the data before you act on it, not after something goes wrong.
Signal weights update based on realized win-rate outcomes. Competitors ship static models and leave calibration to you. This system corrects itself with every completed cycle.
