How to do deep crawling with RestAPI?

[phamgiang2510]

I've hosted an instance of Crawl4AI by docker with the latest image version of 0.6.0-r2. The crawl job for a single page with RestAPI is working fine, but I don't know how to do a deep crawl, and can't find any documentation for it.

I've tried to POST the following payload to the /crawl endpoint but it doesn't work:

{
    "urls": ["https://docs.crawl4ai.com/"],
    "crawler_config": {
        "deep_crawl_strategy": {
            "type": "BFSDeepCrawlStrategy",
            "max_depth": 2,
            "max_pages": 20,
            "include_external": false,
            "filter_chain": {
                "type": "URLPatternFilter",
                "patterns": [
                    "/core/*"
                ]
            }
        }
    }
}

Can anyone help me? Thanks!
