query: bitcoin price tools 1 / rank: 1 tools 1 / name: live_price tools 1 / description: Real-time cryptocurrency price lookup for any coin - BTC, ETH, SOL, DOGE, BNB, XRP, MATIC, AVAX, ADA, LINK, and 100+ others. Uses CoinGecko first, Coinbase as a secondary no-key provider, then the most recent cached verified value with its age if both live providers are unavailable. Returns live USD price, 24h % change, and market cap when verified. Use for ANY 'what is X price', 'X price now', 'how much is X', or 'X USD' query. Do NOT use market_pulse for specific coin prices - use this tool. tools 1 / input hints / type: object workflows 1 / id: prices workflows 1 / title: Check a live price workflows 1 / ask: Check a stock or crypto price and help me set an alert. workflows 1 / result: A sourced price check and an alert setup. workflows 1 / tools 1: live_price workflows 1 / tools 2: zambo_watch workflows 1 / first step free: true

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.
