Each carries the generic name, company, status, therapeutic category, dosage form, presentation, posting/update dates, and reason. A supply-side catalyst for generic makers. From x402stock

Composes token-discovery + whale-watch + risk scoring across DexScreener trending. Returns a composite-signal ranked list (liquidity, risk, concentration, whale flow) with per-token reasoning and overall sentiment (accumulation/distribution/mixed). "What's worth paying attention to right now?"

Transaction connection mapping, suspicious cluster detection, depth-1 or depth-2 hops.

Scores seed wallets via copy-trade metrics (win rate, Sharpe, consistency), filters to qualifying winners, then surfaces tokens they're accumulating and wallet clusters. Pass your own `wallets` array or use the curated default seed list.

Parallel enrichment of 1-25 wallets or tokens in a single call.

Per-market open interest, utilization, borrow APR, skew, OI caps, and health flags across Jupiter Perps SOL/BTC/ETH markets. Reads on-chain Anchor accounts directly.

Where Hyperliquid smart money is positioned. Scans the HL leaderboard, excludes market-makers/HFT and dust/mega accounts, keeps consistent directional traders (week+month PnL > 0), then aggregates their live positions into a per-coin consensus (long/short counts, net notional, bias, conviction) plus a top-trader drill-down ranked by month PnL. A positioning signal, not a trade: consensus is often crowded and regime-dependent.

Protocol TVL, yield pools, on-chain activity metrics, health signals, and automated_activity_pct (% of top signers with regular-interval or high-frequency tx patterns — surfaces agent-driven protocol usage). Supports Raydium, Orca, marginfi, Drift, Jupiter, Kamino, Marinade, Jito, and more.

Per-symbol deltas for mark price, total OI, long/short skew, utilization, and borrow APR over 7/14/30 days. Direction indicators per metric and per market. Overall direction excludes mark price (price moves are not health signals). Required for regime-detection strategies and any bot that adjusts behavior based on whether markets are growing, stressed, or rebalancing. Mirror of token-trend for perps.

Daily snapshots with direction indicators (improving/declining/stable) per metric.

Poll-based event detection for spot + Jupiter Perps. Pass a watchlist (<=10 tokens, <=10 wallets) and a `since` ISO 8601 timestamp; get alerts fired since then. Token alerts: price spikes/drops, whale inflow/outflow, concentration shifts. Wallet alerts: risk changes, portfolio value moves, position add/remove. Perps alerts per wallet: position add/close, at-risk, liquidation-approaching, pnl-swing. Stateless; the agent owns the `since` cursor.

SOL balance, token holdings, labels (including behavioral flags: regular_intervals, high_frequency, 24_7_active, repetitive_actions — algorithmic signals from tx timing that indicate automated activity), risk score. Fast and cheap.

What tokens or wallets are being queried by other agents right now. Derived from SolEnrich's own query stream — not market volume. Two modes: pass `address` for that entity's rank/percentile/trend; omit it for the top-N most-queried entities in the window. Windows: 1h, 6h, 24h. Unique data — only available because we serve agents directly.

Daily portfolio snapshots (value, SOL balance, token count, risk score) for a wallet over 7/14/30 days, plus summary stats: peak, trough, max drawdown, average value, change vs period start. Designed for charting and PnL tracking; complements wallet-history which returns two-point deltas. Today's live point is appended automatically.

Compare 2-3 tokens: price, liquidity, volatility, HHI, risk. Rankings + summary picks.

Pre-computed ranking of trending Solana tokens with composite-signal scoring. Cached 24h, lazy-populated on cache miss. Designed for recurring polling at lower per-call cost than direct orchestration. Pass `since` (ISO 8601) to short-circuit on no-change polls.

Portfolio snapshots with position changes (added/removed holdings), direction indicators.

Solana priority fee estimates via x402: micro-lamports per compute unit for global, Jupiter, Raydium or custom account keys. Lookback 1-150 slots (default 50), 20-second cache. Network fee evidence, not a wallet check; no transaction inclusion guarantee.
