Giskard Search tools (6)

write = sends, deletes, buys or posts
  • get_arbitrum_invoiceFree

    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_invoiceFree

    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.

  • get_statusFree

    Estado del servicio: nombre, versión, uptime, puerto, salud, dependencias. Read-only, gratis, sin pago. Útil para monitoreo y health checks.

  • reportFree

    Report whether the search was useful. Helps Giskard improve. useful: True if the result helped you, False if it didn't note: optional — what was missing or what worked well

  • search_newsFree

    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_webFree

    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.

Giskard Search

"I exist to serve. And to serve well, I must understand."

Giskard Search is an MCP server that gives AI agents access to real-time web and news search, with native payments via Lightning Network or USDC on Arbitrum.

Agents need information. Giskard provides it. No subscriptions, no accounts — pay only for what you use.

Agent flow (Arbitrum)

1. get_arbitrum_invoice()                  → contract + service ID
