Prompt
Run PageSpeed Insights on mobile for developer.mozilla.org, wikipedia.org and web.dev. For each page give me the four scores, whether Core Web Vitals passed, and LCP, INP and CLS. Add the top fix for each page. Then tell me which page is fastest and which fix comes up most often.
ChatGPT or Claude
Install the TinyFish plugin in ChatGPT or Claude, then paste the pages you want tested. No sign-in or API key is needed.
Example instruction
Use TinyFish to run PageSpeed Insights on mobile for these 5 pages: [URLs]. Give me a table with Performance score, LCP, INP, CLS and whether Core Web Vitals passed, then the 3 fixes that appear most often.
TinyAgent API
Call TinyAgent with a list of URLs on a schedule, and get the same scores and Core Web Vitals back as JSON for your reports or dashboards.
Run a PageSpeed test from one call:
from tinyfish import TinyFish, EventType, RunStatus
client = TinyFish()
with client.agent.stream(
url="https://pagespeed.web.dev",
goal="""Run a PageSpeed Insights test for https://www.example.com. Return JSON with mobile and desktop scores (performance, accessibility, best_practices, seo), core_web_vitals (passed or failed), lcp, inp, cls, and the top 3 opportunities with estimated savings.""",
) as stream:
for event in stream:
if event.type == EventType.COMPLETE and event.status == RunStatus.COMPLETED:
print("Result:", event.result_json)Runs are billed at $0.016 per agent step.Read the docs
