| name | serpapi-web-search |
| description | Search the web using SerpApi's 100+ search engines. Use this skill whenever the user needs current or web-sourced information: researching a topic, checking recent news, comparing products or prices, finding local businesses, searching images or videos, or looking up academic papers, flights, hotels, or stocks — even if they don't explicitly ask to "search the web." Default to google_light for speed. Supports Google, Bing, DuckDuckGo, YouTube, Amazon, Maps, Scholar, and more. |
| compatibility | Requires one of: a native serpapi_search tool; or the serpapi CLI (brew tap serpapi/homebrew-tap && brew install serpapi-cli); or an SDK; or outbound network access with curl. All paths require a SERPAPI_KEY. |

Invocation
Use the first available method:
1. MCP tool — use serpapi_search if available (source):
serpapi_search(params={"engine": "google_light", "q": "query"}, mode="compact")
2. serpapi-cli — preferred shell fallback; optimized for AI agents (source):
serpapi search engine=google_light q="your query"
serpapi search --fields "organic_results[0:3]" engine=google_light q="your query"
serpapi search --jq ".organic_results[0:3]|[.[]|{title,link}]" engine=google_light q="your query"
Install: brew tap serpapi/homebrew-tap && brew install serpapi-cli
Auth: SERPAPI_KEY env var, --api-key flag, or serpapi login.
Exit codes: 0 success · 1 API error · 2 usage error. Errors are JSON on stderr.
3. SDK — when writing code: see rules/sdks.md — Python, JS, Go, Ruby, PHP, Java, .NET.
4. curl — universal fallback:
curl -G "https://serpapi.com/search.json" \
--data-urlencode "q=your query" \
--data-urlencode "engine=google_light" \
--data-urlencode "api_key=${SERPAPI_KEY}"
Engine Selection
Pick the engine that matches the user's intent:
| Use Case | Engine |
|---|
| General web (default) | google_light |
| Comprehensive (knowledge graph, local pack) | google |
| News | google_news_light |
| Images | google_images_light |
| Shopping / prices | google_shopping_light |
| Alternative web | bing |
| Privacy-first | duckduckgo |
| Academic / research | google_scholar |
| Local / maps | google_maps |
| Video | youtube |
| SerpApi's own index (alpha, no Google/Bing) | search_index |
Prefer _light variants — they're faster and cheaper. Use the full engine only when you need knowledge graph, local pack, or featured snippets.
For engines not listed above (flights, hotels, jobs, finance, patents, etc.), read rules/ENGINES.md.
