The credibility layer for the agentic web.

Every AI agent that researches a topic, writes a brief, or synthesises sources needs to know: who actually knows what they're talking about? That's the call Amygdala answers. Before your agent cites a source or quotes an authority, it calls /api/v1/index/ or /api/v1/detail/ to verify authority.

RAG pipelines Rank retrieved sources by their author's authority score before passing them to the LLM.
Research agents Let the agent discover the top verified authorities on a topic, then prioritise their publications.
Content tools Auto-generate "according to [verified authority]" attributions backed by real authority data.
4 MCP tools — available to any MCP-compatible AI

RAG-ready output

Structured JSON with authority scores, bios, and social handles — ready to inject into your LLM context.

Verified signals only

No bots, no AI slop. Every authority is verified through our multi-layer methodology.

Usage-based pricing

Pay per query. No minimums, no seat licenses. Top up your balance and scale as needed.

Continuously updated

The index is continuously synced so your queries always reflect the current state of expertise on any topic.
