crypto_regime
Crypto market regime classifier
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.

crypto_sentiment
Crypto / text sentiment scorer
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.

factcheck
Fact-check a claim
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.
