Build a reusable CoinMarketCap workflow in NextBrowser

Use NextBrowser Automation Studio to record a CoinMarketCap Top 5 task, inspect the workflow and verify a Top 10 JSON artifact after changing the limit.

About this reference video

The recording demonstrates collecting five CoinMarketCap Trending entries, replaying the task, converting it to an editable workflow and changing the limit to ten. The final artifact contains ten entries. The instructions below map that sequence to NextBrowser Automation Studio; current page layout and available fields may differ.

Overview

A successful one-off browser task is not yet a reusable extraction workflow. NextBrowser Automation Studio connects recording, editable workflow actions and local artifacts. This guide checks each transition so replay captures the requested data, not just the visible navigation.

What happens in the video

The agent records a CoinMarketCap Trending task that collects five entries and saves a JSON artifact. The operator replays the recording, converts it to an editable workflow, changes the collection limit from five to ten, and runs it again. The final frames show a completed workflow and a Top 10 JSON artifact containing ten entries.

Before you start

  • NextBrowser with a running research profile and an authenticated local agent
  • Access to Automation Studio in the installed release
  • The CoinMarketCap Trending page, required fields and an agreed collection limit

Run this in NextBrowser

Follow these steps in your own NextBrowser workspace. The video summary records the source demonstration; your result needs the checks below.

  1. Prepare the profile and recording

    Start the intended profile in NextBrowser, open CoinMarketCap Trending and confirm the page in Live View. In Automation Studio, use Recorder to start recording the task against that context.

  2. Collect five entries and inspect the artifact

    Ask the agent to collect the first five entries in the visible Trending order with rank, name, symbol and source link, then save JSON. Stop the recording and review it. Inspect the actual artifact in Artifact Center rather than accepting a completed run status as proof of extraction.

  3. Replay and review the captured actions

    Replay the recording and compare its output with the current page. Inspect whether structured data collection and artifact saving were captured: recording visible browser navigation can miss silent extraction work. Fix missing actions before treating replay as equivalent to the original task.

  4. Edit the workflow limit

    Open the editable workflow in Workflow Builder and inspect its actions and arguments. Change the collection limit from five to ten in the relevant extraction step, preserving page selection, fields and artifact saving. Do not assume renaming the workflow changes its behavior.

  5. Verify ten current entries

    Run the reviewed workflow and open the resulting JSON in Artifact Center. Count ten unique entries and compare their order and fields with the current Trending page. Artifacts are local to this installation; save or export the file explicitly when you need to share it.

Suggested prompt

In NextBrowser profile [profile name], open CoinMarketCap Trending and confirm the visible list. Collect the first five entries in the current displayed order with rank, name, symbol and source URL. Save a JSON artifact and report the actual entry count and any missing fields. Keep this task to public-data research; do not trade or connect a wallet.

Replace the placeholders, then send this in NextBrowser Chat with the intended profile and agent selected. This is a suggested task, not the recording transcript.

What to verify in your run

  • A reviewed workflow whose extraction limit can be changed independently of its title
  • A local JSON artifact verified to contain ten unique entries after the modified run

Questions about this workflow

Why can replay finish without the expected dataset?

A recording can capture browser navigation and visible interaction without every extraction step. Inspect the workflow actions and artifact contents, especially when the original task used agent reasoning or silent data collection.

Are Artifact Center files automatically synced?

The current implementation stores artifacts locally. Export or save the file through the available artifact controls when you need a portable result.
