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_KEY environment variable. Blank → the keyless public endpoint is used.
• Endpoint (optional). KEENABLE_API_URL overrides the base URL (HTTPS enforced; plain http only 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.

Develop
