--- title: "Setting Google Search By Image SERP Tasks" url: "https://docs.dataforseo.com/v3/serp/google/search_by_image/task_post/" date: "2026-06-06" --- ## Setting Google Search By Image SERP Tasks Google Search By Image SERP API provides up to top 100 search engine results based on the image you specified. These results are specific to the selected location (see [the List of Locations](https://docs.dataforseo.com/v3/serp/google/locations.md)) and language (see [the List of Languages](https://docs.dataforseo.com/v3/serp/google/languages.md)) settings. There are two different priorities that stand for the relative speed of task execution: normal and high. ![checked](https://docs.dataforseo.com/v3/wp-content/themes/dataforseo/assets/img/icons/checked-circle.svg) POST https://api.dataforseo.com/v3/serp/google/search\_by\_image/task\_post Pricing Your account will be charged only for setting a task. The cost can be calculated on the [Pricing](https://dataforseo.com/pricing/serp/google-search-by-image-serp-api "Pricing") page. All POST data should be sent in the [JSON](https://en.wikipedia.org/wiki/JSON) format (UTF-8 encoding). The task setting is done using the POST method. When setting a task, you should send all task parameters in the task array of the generic POST array. You can send up to 2000 API calls per minute, with each POST call containing no more than 100 tasks. If your POST call contains over 100 tasks, the tasks over this limit will return the `40006` error. Visit [DataForSEO Help Center](https://dataforseo.com/help-center/best-practices-low-volume-serp-api-payload) to get practical tips for request handling depending on your SERP API payload volume. You can retrieve the results of completed tasks using the unique task identifier `id`. Alternatively, we can send them to you as soon as they are ready if you specify the `postback_url` or `pingback_url` when setting a task. Note that if your server doesn’t respond within 10 seconds, the connection will be aborted by timeout, and the task will be transferred to the [‘Tasks Ready’](https://docs.dataforseo.com/v3/serp/google/images/tasks_ready.md) list. The error code and message depend on your server’s configuration. See [Help Center](https://dataforseo.com/help-center/pingbacks-postbacks-with-dataforseo-api) to learn more about using pingbacks and postbacks with DataForSEO APIs.
