Live OnPage Lighthouse JSON


‌The OnPage Lighthouse API is based on Google’s open-source Lighthouse project for measuring the quality of web pages and web apps.

Lighthouse measures the quality of web pages by running a series of individual tests for each specific feature or metric to produce a numeric score and generate a report. It can run audits for performance, accessibility, progressive web apps, SEO, and conformity with best practices. You can find the full list of OnPage Lighthouse API audits in the Lighthouse Audits section. The results of the Lighthouse run will help you to easily strengthen the audited page or web app.

OnPage Lighthouse API is based on an open-source Lighthouse project. You can find the official documentation here.

All POST data should be sent in the JSON format (UTF-8 encoding). 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 only one task.

To get more information about the OnPage Lighthouse API configuration parameters, please refer to the official documentation of the Lighthouse project.

Description of the fields for setting a task:

Field name Type Description
url string target URL
required field
target page should be specified with its absolute URL (including http:// or https://)
example:
https://dataforseo.com/
for_mobile bool applies mobile emulation
optional field
if set to true, Lighthouse will use mobile device and screen emulation to test the page against mobile environment
if set to false, the results will be provided for desktop
default value: false
categories array categories of Lighthouse audits
optional field
each category is a collection of audits and audit groups that applies weighting and scoring to the section (see official definition)

if you ignore this field, we will return data for all categories unless you specify audits
use this field to get data for specific categories you indicate here

possible values:
seo, pwa, performance, best_practices, accessibility

audits array Lighthouse audits
optional field
audits are individual tests Lighthouse runs for each specific feature/optimization/metric to produce a numeric score (see official definition)

if you ignore this field, we will return data for all audits
use this field to get data for specific audits you indicate here

note that some audits do not belong to a specific category and are stand-alone page quality measurements

in general, there can be several use cases:

1. if you ignore categories, you can use this field to get data for the specified audits only
for example, if you ignore "categories" and specify "audits": ["metrics/cumulative-layout-shift","metrics/largest-contentful-paint","metrics/total-blocking-time"], you will get data only for these audits

2. if you specify a category, you can use this field to additionally receive audits that do not belong to the category(-ies) you specified
for example, if you specify "categories": ["seo"] and "audits": ["metrics/cumulative-layout-shift","metrics/largest-contentful-paint","metrics/total-blocking-time"], you will get only these audits under “performance” and all audits under “seo”

you can get the full list of possible audits here

tag string user-defined task identifier
optional field
the character limit is 255
you can use this parameter to identify the task and match it with the result
you will find the specified tag value in the data object of the response


As a response of the API server, you will receive JSON-encoded data containing a tasks array with the information specific to the set tasks.

Description of the fields in the results array:

Field name Type Description
version string the current version of the API
status_code integer general status code
you can find the full list of the response codes here
Note: we strongly recommend designing a necessary system for handling related exceptional or error conditions
status_message string general informational message
you can find the full list of general informational messages here
time string execution time, seconds
cost float total tasks cost, USD
tasks_count integer the number of tasks in the tasks array
tasks_error integer the number of tasks in the tasks array returned with an error
tasks array array of tasks
        id string task identifier
unique task identifier in our system in the UUID format
        status_code integer status code of the task
generated by DataForSEO; can be within the following range: 10000-60000
you can find the full list of the response codes here
        status_message string informational message of the task
you can find the full list of general informational messages here
        time string execution time, seconds
        cost float cost of the task, USD
        result_count integer number of elements in the result array
        path array URL path
        data object contains the same parameters that you specified when setting a task
        result array results of Lighthouse audit
this array will include data according to the parameters you specified when setting a task;

all fields and their descriptions are available in the official documentation by this link.
