Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (12)

crypto_regimeread-onlyMarket 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_sentimentread-onlySentiment 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.
factcheckread-onlyFact-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.
gridparamsread-onlyPAID PER CALL ($0.05 USDC on Base via x402). Recommended grid-trading parameters (range, spacing, order size) for a pair and capital amount, derived from live 24h market structure. Unpaid calls return the exact x402 payment terms.
priceread-onlyPAID PER CALL ($0.005 USDC on Base via x402). Current price, 24h/7d change, and a simple signal for a major crypto asset. Unpaid calls return the exact x402 payment terms.
pricecheckread-onlyCurrent 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.
regimeread-onlyPAID PER CALL ($0.03 USDC on Base via x402). Market regime (chop / trend_up / trend_down / high_vol) plus a grid-suitability verdict, computed from live 24h market structure. Unpaid calls return the exact x402 payment terms.
riskread-onlyPAID PER CALL ($0.02 USDC on Base via x402). Volatility / drawdown risk regime (low / med / high) vs the 30-day baseline for a major crypto asset. Unpaid calls return the exact x402 payment terms.
sentimentread-onlyPAID PER CALL ($0.005 USDC on Base via x402). Sentiment score (-1..+1) with label for EXACTLY ONE of `text` or `asset`. Unpaid calls return the exact x402 payment terms.
summarizeread-onlyTight 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.
telemetryread-onlyPAID PER CALL ($0.005 USDC on Base via x402 — no signup, no API key). Telemetry for an AI-managed long-horizon crypto portfolio: allocation, reconciled profit-and-loss, signal votes, and the human-approval trail for every trade. Unpaid calls return the exact x402 payment terms.
token_riskread-onlyVolatility / 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.
