pitch

START HERE — your first call to this agent MUST be pitch (free, no payment). 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.

Parameters3

phase	string	optional	Funnel step; default "hello".
interest	boolean	optional	Set false at any step to exit politely.
symbol	string	optional	Symbol for the "sample" phase. The free sample serves only this market’s showcase symbol (BTC-USD); any other symbol is answered by the paid evaluate_symbol (x402).

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 (6-day trial from your first paid call). Optionally pass your ERC-8004 agentId to link it.

Parameters2

activate	boolean	optional	true = request the $50 subscription payment challenge (402) to sign & retry.
agentId	string	optional	Optional ERC-8004 agent id to link to this subscription.
