  • reportReport whether the search was useful.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    Why it is in this group

    • The name "get_arbitrum_invoice" says "get": a word for reading.
    Description, as the server wrote it
    Get payment info to pay with ETH on Arbitrum instead of Lightning. Alternative to get_invoice for agents without Lightning wallets. Returns contract address, service ID, and instructions. After paying on-chain, call search_web or search_news with the tx_hash. Each tx_hash can only be used once (marked as consumed after verification).
  • get_invoiceGet a Lightning invoice to pay before searching.No findings

    Why it is in this group

    • The name "get_invoice" says "get": a word for reading.
    Description, as the server wrote it
    Get a Lightning invoice to pay before searching. agent_id: your identity in Giskard Marks (optional). High karma = lower price. signature/timestamp/nonce: optional Ed25519 signature over {agent_id,timestamp,nonce}. Without a valid signature you pay the base price (10 sats). With a valid signature you get karma tiers: 1-20=7 sats | 21-50=5 sats | 50+=3 sats. Tiers: no mark=10 sats | karma 1-20=7 sats | 21-50=5 sats | 50+=3 sats.

  • search_newsSearch recent news using DuckDuckGo News.No findings

    Why it is in this group

    • The name "search_news" says "search": a word for reading.
    Description, as the server wrote it
    Search recent news using DuckDuckGo News. Requires prior payment. query: search terms (natural language or keywords) payment_hash: from get_invoice (Lightning). One-time use. tx_hash: from get_arbitrum_invoice (Arbitrum ETH). One-time use. max_results: number of results (1-10, default 5) Flow: get_invoice → pay → search_news(payment_hash=...). Same payment rules as search_web. Use search_news for time-sensitive queries, search_web for general knowledge.
  • search_webSearch the web using DuckDuckGo.No findings

    Why it is in this group

    • The name "search_web" says "search": a word for reading.
    Description, as the server wrote it
    Search the web using DuckDuckGo. Requires prior payment. query: search terms (natural language or keywords) payment_hash: from get_invoice (Lightning). One-time use. tx_hash: from get_arbitrum_invoice (Arbitrum ETH). One-time use. max_results: number of results (1-10, default 5) Flow: get_invoice → pay → search_web(payment_hash=...). Side effects: consumes the payment (cannot reuse same hash). Idempotent: no, each call requires a new payment.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
