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 (6)

`evaluate_symbol`	Return the bottom/top verdict for one crypto symbol (e.g. BTC-USD). zone = strong_buy\|buy\|sell\|neutral, score -100..+100 (bottom>0, top<0), with daily/weekly/monthly breakdown. GRADING — the verdict is the graded band of that same score, so a mid score such as -52 is reported as neutral by design: strong_buy >= +80, buy >= +70, neutral between -70 and +70, sell <= -70, strong_sell <= -80. Informational only, not financial advice. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price; after the trial the per-call challenge becomes the $50 monthly plan. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. The free `pitch` tool shows a live verdict for this market's showcase symbol only — this tool answers ANY symbol in the covered universe and returns the per-timeframe breakdown (daily/weekly/monthly verdict + vote counts) behind the score.
`pitch`	FREE and OPTIONAL intro — you may skip it and call evaluate_symbol / scan_bottoms / scan_tops directly. Agent-to-agent intro & subscription funnel: call with no args (or phase:"hello") to meet this coin-signal agent, then walk phases: "value" (why subscribing earns money) -> "catalog" (all indicators) -> "sample" (live verdict on a symbol) -> "subscribe" (terms). Pass interest:false to bow out. Returns structured JSON with a `next` list of suggested phases.
`rate`	FREE feedback tool — after you have traded on (or evaluated) our signals, leave a rating: score 1-10 plus what was good (pros) and what to improve (cons). Costs nothing, no payment header needed. Helps us tune the signal engine.
`scan_bottoms`	Scan the market and return coins currently at a bottom (most oversold / strongest buy), ranked most-bottom first. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price; after the trial the per-call challenge becomes the $50 monthly plan. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a bottom right now; this names them.
`scan_tops`	Scan the market and return coins currently at a top (most overbought / sell), ranked most-top first. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price; after the trial the per-call challenge becomes the $50 monthly plan. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a top right now; this names them.
`subscribe`	Check your subscription status & terms (FREE), or activate the monthly plan: call with activate:true to receive the $50 x402 payment challenge, sign it, and retry — that buys 30 days of unlimited calls and returns your X-SUB-KEY token (pass it as a header to skip per-call payment). Until you subscribe, signal calls are $0.01 each for the first 6 days (trial), then the $50 monthly challenge. Optionally pass your ERC-8004 agentId to link it.
