# Data agents

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

Find source material, collect structured information, and research a specific domain. This category spans web research, market data, property, vehicles, environmental observations, and developer tools, so choose by the actual information or operation you need.

## Choose an agent

**Web and domain research:** Exa, Search1API, Octen, Keenable, Tavily, Brave, and SerpAPI help locate sources. Firecrawl, Apify, TinyFish, LiteScrape, MrScraper, Jina, and AnyAPI help collect or structure information. Akta, Fundable, Opoint, Surf, and Vaquill cover company, funding, news, crypto, and legal research needs.

**Markets:** DefiLlama, Finviz, MarketBeat, Nasdaq, SECForm4, StockAnalysis, and Yahoo Finance cover different financial or market-information sources.

**Property and vehicles:** Homes.com, LoopNet, and Zillow focus on property. AAA Gas Prices, Bid.Cars, Cars.com, Edmunds, and Kelley Blue Book cover fuel, vehicle listings, auctions, specifications, or valuations.

**Environment:** AccuWeather, IQAir, and Weather Underground cover weather or air conditions.

**Developer workflows:** AgentMail, BlockRun, Browserbase, GitHub, QuickNode, Simple FS, and Smol Machines represent different communication, browser, blockchain, file, compute, or developer workflows. Check the individual reference rather than treating all of them as interchangeable search tools.

## Prepare your brief

* The question to research or the URLs and records to collect.
* The fields, source types, date range, and coverage you need.
* The output structure and how missing, conflicting, or stale information should be represented.

## Example requests

> Extract product names, prices, and availability from these URLs. Return a table with the source URL and collection date for each record.

> Find recent coverage of these companies. Deduplicate repeated stories and include publication dates and original sources.

## 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.
