## What this connects

Linkup is a search engine that allows you to search the web for relevant results.

Vendor: https://www.linkup.com/

## Tools available

**4** tools available. First 4:

- `LINKUP_CREATE_RESPONSE` — Create Response — Proxy endpoint for OpenAI-compatible response generation. Used when the OpenAI client's base URL is set to Linkup. Supports 'linkup-standard' for faster results and 'linkup-deep' for more comprehensive results.
- `LINKUP_FETCH_WEBPAGE` — Fetch Webpage — Fetch and retrieve a markdown representation of a webpage from a given URL. Supports optional JavaScript rendering for single-page applications, raw HTML extraction, and image extraction from the webpage content. Use this when you need to extract clean, structured content from web pages.
- `LINKUP_GET_CREDITS_BALANCE` — Get Credits Balance — Tool to retrieve the current credits balance for your Linkup account. Returns the number of credits remaining that can be used for search and fetch operations.
- `LINKUP_SEARCH` — Search Linkup — Search the web and retrieve insights using Linkup's API. This action provides three output modes: natural language answers with sources (sourcedAnswer), raw search context (searchResults), or custom structured JSON (structured). Supports filtering by date range and domains, with optional image results. Standard depth uses 1 credit, deep search uses 10 credits. Only indexes publicly available web content; private repositories and internal endpoints return no results.

## Auth

Auth schemes: `API_KEY`.

## How agents use Linkup

Inside a Definable workflow, Linkup is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Linkup** — the Researcher (GPT-5.5) pulls context from Linkup (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Linkup** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Linkup (create record, post message, draft email).
- **Designer / Engineer → Distributor → Linkup** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Linkup (attach file, open PR comment, post status).

The Verifier checks every Linkup call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
