Measured tools (12)

• crypto_regime read-only

  Market regime (chop / trend_up / trend_down / high_vol) for a major crypto pair, computed from live 24h market structure by a production-grade classifier. Returns a grid_suitability verdict (good/poor/etc) telling an agent whether current conditions favor range-bound (grid) strategies or trend-following ones. Use this before deciding to deploy a grid bot, mean-reversion strategy, or trend-follow strategy on SOL, XLM, BTC, ETH, XRP, DOGE, LTC, or ADA.

  Parameters:

  • asset (required) — string — Asset symbol, one of: SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• crypto_sentiment read-only

  Sentiment score (-1 to +1) with a bullish/neutral/bearish label, for either raw text or a crypto asset's recent price action, via an LLM. Give it EXACTLY ONE of `text` (free-form text to score) or `asset` (one of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA). Useful for agents building trading signals, news pipelines, or social-listening tools without running their own LLM sentiment call.

  Parameters:

  • text — string — Free text to score (omit if using `asset`)
  • asset — string — Asset symbol to score sentiment for (omit if using `text`)

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• summarize read-only

  Tight 3-5 sentence summary of a URL or a raw text block, via an LLM. Give it EXACTLY ONE of `url` (a page to fetch and summarize) or `text` (raw text to summarize directly). For agents/pipelines that need a fast, information-dense digest without running their own LLM call or web fetch.

  Parameters:

  • url — string — Page URL to fetch and summarize
  • text — string — Raw text to summarize directly

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• factcheck read-only

  Fact-check verdict (true / false / uncertain) with a confidence score (0-1) and a 1-2 sentence reasoning for any factual claim, via an LLM. Useful for content moderation, chatbot/agent guardrails, and misinformation screening. Returns 'uncertain' for opinions or claims requiring live/real-time data.

  Parameters:

  • claim (required) — string — The factual statement to verify

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• pricecheck read-only

  Current price, 24h and 7d percent change, and a simple bullish/bearish/neutral signal for a major crypto asset. Low-latency market-data lookup for dashboards, bots, and alerts — one of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA.

  Parameters:

  • asset (required) — string — Asset symbol, one of: SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• token_risk read-only

  Volatility / drawdown risk regime (low / med / high) for a major crypto asset, extending the same classifier behind crypto_regime. Tells an agent whether current volatility is elevated vs its 30-day baseline — useful for position sizing and stop-placement logic. One of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA.

  Parameters:
