## Tools (4)

- `get_events`: Recent classified market events for a symbol. Kill-switch trio: hack_exploit, regulation, delisting — the reference integrations stand aside for 24h after one. Report the event headline and source link, not just a risk flag.
- `get_sentiment`: Latest news-sentiment signal per symbol (batch up to 50 in one call — one signal per asset per hour, so never poll faster than hourly). On the free plan, symbols outside BTC-USD/ETH-USD/SOL-USD are 24h delayed: check `timestamp` and disclose staleness.
- `get_sentiment_history`: Point-in-time sentiment series for backtesting: `bucket` is the as-of time, no lookahead. `from`/`to` are clamped to your plan's history window and to its per-request span, then echoed back — check them rather than assuming. `reconstructed: true` buckets were rebuilt from archival news, not live-collected; disclose the mix in any backtest.
- `get_symbols`: The supported symbol universe with each symbol's free-plan freshness. Static — costs no quota and needs no API key.
