# /v1/deep-research* is deprecated

Firecrawl API deprecated /v1/deep-research* without giving a shutdown date yet.

Firecrawl API has deprecated the /v1/deep-research* endpoint without a shutdown date. Calls made to this endpoint will eventually fail, as the legacy route is being retired. Check your implementation for any requests sent to /v1/deep-research* to determine if your service is affected.

## What to use instead

Build the research flow on POST /v2/search with scrapeOptions instead of /v1/deep-research.

- API: Firecrawl API (api.firecrawl.dev)
