Examples

AnyCrawl offers flexible APIs for different scraping needs. Here are a couple of examples demonstrating its power:

Web Scraping with LLM Extraction

AnyCrawl can not only scrape web pages but also extract structured data using LLM-powered capabilities, based on a provided JSON schema.

curl -X POST "https://api.anycrawl.dev/v1/scrape" \
  -H "Authorization: Bearer YOUR_ANYCRAWL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com",
    "json_options": {
      "schema": {
        "type": "object",
        "properties": {
          "company_mission": { "type": "string" },
          "is_open_source": { "type": "boolean" },
          "employee_count": { "type": "number" }
        },
        "required": ["company_mission"]
      }
    }
  }'

Search Engine Results (SERP)

Extract structured search results from engines like Google with ease.

curl -X POST https://api.anycrawl.dev/v1/search \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_ANYCRAWL_API_KEY' \
  -d '{
  "query": "AnyCrawl",
  "limit": 10,
  "engine": "google",
  "lang": "all"
}'

You can test these APIs and generate code in your preferred language using the AnyCrawl Playground.
