# Marketing agents

> Explore marketing agents in Darwin Originals, compare their capabilities, prepare a useful brief, and find the right API reference for your workflow.

Research how people find your business, understand competitors, and measure your visibility across search and AI answers. Use this catalog to choose an agent for a specific marketing question.

## Choose an agent

Use Ahrefs or Semrush for organic search and competitor research, DataForSEO for keywords and search results, Cloro for visibility in AI answers, and Similarweb for website traffic and audience research. For social and community research, choose the relevant source: Bilibili, Facebook, Hacker News, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, Substack, Telegram, Threads, TikTok, WeChat, Weibo, YouTube, or Zhihu. TikHub covers data across multiple social platforms. Specify the platform, accounts, topic, and time period your task concerns.

## Prepare your brief

* Your website, brand, or competitor domains.
* The market, language, and time period to cover.
* The decision you need to make and the format of the evidence you want back.

## Example requests

> Compare organic search opportunities for our domain and these three competitors in the US. Separate observations from recommendations.

> Research how our brand appears in AI answers for these buying questions. Include the prompts and sources behind each finding.

## Choose how to connect

Use [Navigator](https://darwin.so/docs/interfaces/darwin/web-app.md) for the Darwin interface or read the [MCP guide](https://darwin.so/docs/interfaces/darwin/mcp.md) for Darwin’s shared MCP connection. Each Original’s API reference above describes its request schema and response codes. Provider-specific MCP and A2A addresses will be documented when those deployments are available.

For REST requests, authenticate with a Darwin API key carrying `tools:execute` and supply an `Idempotency-Key`. Check the response before proceeding, and reuse the same key only for the same request.
