Zero-API-Key Web Search
Search infrastructure for AI agents.
Free by default. MCP-ready. LLM-context aware. Production-grade when you opt in.
What It Does
Zero-API-Key Web Search is a local-first, MCP-native search and evidence-verification toolkit for AI agents. It gives your agent live web search, LLM-optimized context extraction, claim verification with weighted evidence scoring, and citation-ready evidence reports — all without requiring an API key by default.
The verification model (evidence-aware-heuristic-v3) classifies sources as supporting, conflicting, or neutral using keyword overlap, domain-quality heuristics, freshness, and optional page-aware rescoring. This project does not perform fact-level proof or logical entailment; it is a signal amplifier for agent grounding decisions.
