How to scrape crypto market data (and why fintech startups should care)

Crypto markets move fast. If your fintech startup is still copying data manually from coin pages, you are already behind the decision you need to make.

This guide walks through exactly how to extract structured crypto market data from a coin detail page using Minexa, a Chrome extension that turns any web page into a clean, exportable dataset with no code required.

What data lives on a crypto coin detail page

A typical coin detail page contains more structured data than most people realize. Beyond the current price, you will usually find market cap, 24-hour trading volume, circulating supply, all-time high, percentage change across multiple timeframes, exchange listings, and sometimes social or developer activity metrics.

All of that is extractable. And for a fintech startup, that data can feed price alert systems, portfolio tracking features, market comparison tools, or internal research dashboards.

Step-by-step: scraping a coin detail page

Step 1. Install the Minexa Chrome extension. Go to the Chrome Web Store and add Minexa to your browser. No account setup friction, no configuration before you start.

Step 2. Navigate to the coin page you want to scrape. Open the detail page for the asset you are targeting, for example a Bitcoin or Ethereum overview page on any public crypto data source.

Step 3. Let Minexa detect the page structure. Minexa scans the page automatically. It identifies repeating data points, including values that are not visually obvious but exist in the page code, such as raw numeric values behind formatted strings. This takes a few seconds to a couple of minutes on the first run.

Step 4. Confirm what was detected. You will see the fields Minexa found. You do not need to name or point to anything manually. If you are unsure what fields are available, Minexa surfaces and ranks the most relevant data points for you automatically.

Step 5. Run the extraction. Once confirmed, the job runs. For a detail page, this is typically a single structured result with all the coin metrics in their own columns.

Step 6. Export to your format of choice. Export to Excel, Google Sheets, or JSON. Each data point gets its own column. The output is clean and ready to use without any reformatting.

Tracking changes over time

A single extraction gives you a snapshot. What makes this genuinely useful for a fintech product is scheduling. Once the scraper is set up, you can schedule it to run daily or at any interval that fits your use case. Each run captures the current state of the page at that moment, so over time you build a historical dataset of price movements, volume shifts, and supply changes without triggering anything manually.

This kind of time-series data is difficult to collect reliably without automation. With Minexa, the setup happens once and the data accumulates on its own.

Why accuracy matters here

Crypto pages often display multiple price-related values close together: current price, 24h change, 7d change, bid, ask. Extraction tools that interpret content rather than read structure can assign the wrong value to the wrong field without signaling that anything went wrong.

Minexa ties each column to a specific position in the page structure. If a value is not found, the output returns empty for that field rather than substituting a nearby number. For financial data going into a product or a model, that distinction matters.

What fintech startups actually do with this data

Building a price alert feature requires a reliable, recurring data feed. Minexa gives you that without an API contract or a third-party data subscription. Competitive research across multiple assets means scraping several coin pages on a schedule and comparing the outputs over time. Internal dashboards for investment decisions need clean, structured inputs, and a scheduled Minexa export fits directly into that workflow.

The extraction setup takes a few minutes. After that, the data collection runs on its own.
