Web Search API

br0ski777/web-search-x402

This is a web search tool that returns structured results with titles, URLs, and snippets through a remote API endpoint hosted at web-search.api.klymax402.com. It uses x402 micropayments, which means you're paying small amounts per search query. The server connects via SSE transport, so it maintains a persistent connection for streaming responses. Reach for this when you need programmatic search capabilities with pay-per-use billing instead of a fixed API subscription. The repository itself is quite minimal with no public documentation, so you'll be working mainly with the hosted endpoint and whatever the x402 payment system requires for setup.
