Deep Reasoning Retrieval by Meaning

$0.0165 per callanswers within 55s

Multi-step neural retrieval with an added reasoning pass via Exa's deep-reasoning mode: the request is expanded, the page index is searched in several passes, and the pages are re-judged before the strongest are returned, each with title, link, published date and author. Up to five extra query variations, the same category, domain and date filters, and text or highlights per hit. One request per call, up to 10 pages; the slowest and dearest mode.

How to run it

Two fields identify it: the Provider and the endpoint key. The key looks like a path because it usually mirrors the Provider's own, but it is an opaque identifier — not a URL you can open. The same provider:endpoint pair is what your Policy lists.

Once: paste this into your agent's chat. The Skill installs the CLI and logs in by itself. For an agent that cannot use a shell, connect it over MCP instead.

Setup prompt
set up https://glasser.ai/SKILL.md

Then ask for this Endpoint:

Agent prompt
Run the Exa Endpoint /search?type=deep-reasoning on Glasser with input {"query":"startups building solid-state batteries for grid storage","numResults":10,"additionalQueries":["solid-state battery grid storage companies"]}
