Giskard Search

Summary

This server wraps DuckDuckGo search behind a pay-per-use wall using Lightning Network or USDC on Arbitrum. You call get_invoice to receive a 10-sat Lightning invoice, pay it through any wallet, then pass the payment hash to search_web or search_news. There's also an Arbitrum flow using an on-chain payment contract. The server uses phoenixd for Lightning payments and implements the x402 HTTP payment protocol. It includes a karma discount system and a report tool for feedback loops. If you're building agents that need live search data without subscriptions or API keys, and you want cryptographic payment verification built in, this handles both the search and the payment rails in one package.

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