lfx-keenable
Keenable web-search and page-fetch components for
Langflow, packaged as a standalone Langflow Extension
Bundle. Two components ship in the keenable bundle group:
- Keenable Search — web search built for AI agents.
- Keenable Fetch — fetch a page and return its main content as markdown.
Both are keyless by default: with no API key they call Keenable's public endpoints; provide a key to use the authenticated endpoints (for higher rate limits).
Install
pip install lfx-keenable
The bundle registers automatically via the langflow.extensions entry-point.
Restart your Langflow server; the components appear in the palette under the
keenable group, and work as agent tools (the query / URL inputs are
tool-enabled).
Configuration
- API key (optional). Set it on the component, or via the
KEENABLE_API_KEYenvironment variable. Blank → the keyless public endpoint is used. - Endpoint (optional).
KEENABLE_API_URLoverrides the base URL (HTTPS enforced; plainhttponly for loopback). The base URL is never a component/LLM-settable input — that would be an SSRF foothold.
Components
Keenable Search
query plus optional per-query filters — site, mode (pro),
and publication / index date bounds (published_after/before,
acquired_after/before). Returns a table of results
(title, url, description, published_at, acquired_at). There is no
max_results input — the API returns a fixed-size result set as-is.
Keenable Fetch
url → the page's main content as markdown plus metadata (title,
description, author, published_at when available). Rejects non-http(s)
schemes and private/internal hosts client-side before sending.
