Reference example
Runs a Google Lighthouse audit on one url and returns the full report: lighthouseVersion, requestedUrl, finalUrl, fetchTime, gatherMode, runWarnings and every audit and category score. for_mobile switches the emulated device, categories and audits narrow the run. 🔴 Measured at 245 KB for a single audit of example.com, the largest response in this provider - a full Lighthouse report is a JSON document, not a metric, and it will dominate an agent’s context. Pass categories or audits to cut it down, and prefer post_dataforseo_on_page_waterfall when the question is simply why a page is slow. Wrapped in DataForSEO’s envelope: data in tasks[0].result, outcome in tasks[0].status_code - a rejected request still returns HTTP 200.

Example

First time? Point any MCP client at https://mcp.aisa.one/mcp — Claude Code, Codex, Cursor, VS Code and the rest. Authorization is OAuth: the client opens a browser, you click Allow once, and there is no key to paste. The commands per client, and what each call costs, are on aisa.one/mcp.

Cost and request rules

Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar.
  • Default request reference estimate (USD): 0.005
  • Cost contract: response_usd
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body

Authorizations

Authorization

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json
url
string

target URL
required field
target page should be specified with its absolute URL (including http:// or https://)

for_mobile
boolean | null

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
string[] | null

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, performance, best_practices, accessibility

audits
string[] | null

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
