CoinCap Crypto & Fiat Rates Scraper

CoinCap Crypto & Fiat Rates Scraper

Scrape live cryptocurrency, fiat, and commodity exchange rates from CoinCap, up to a million per run. Every rate comes with its USD price, 24-hour volume, market cap, and supply data. No API key required. Export to CSV, JSON, Excel, or XML.

CoinCap's public API provides real-time pricing for thousands of digital and traditional currencies, but pulling bulk data or filtering by asset class requires pagination and rate-limit handling. This Actor reads the live rates feed directly, letting you filter by crypto, fiat, or commodity type, or target specific currency IDs like bitcoin, ethereum, or the euro. It returns every matched rate in one consistent, flat schema.

Who uses it	What they scrape CoinCap for
Crypto traders	Monitor real-time prices and 24-hour volume changes across a watchlist of coins.
Financial analysts	Pull fiat and commodity rates alongside crypto to build multi-asset dashboards.
Portfolio trackers	Fetch current market caps and circulating supplies for valuation models.
Data engineers	Ingest normalized rate data into a warehouse on a schedule without managing API pagination.

What it does

This Actor collects live exchange rates from CoinCap by asset type or specific currency ID, and returns each rate as a flat row with its USD price, volume, market cap, and supply metrics.

• 💱 Asset class filtering: pull all rates, or limit to crypto, fiat, or commodity (gold, silver) only.
• 🎯 Currency ID targeting: supply a list of specific IDs like btc, eth, usd, or eur to fetch exactly those rates.
• 📊 Full market metrics: each row includes USD price, 24-hour volume, market cap, supply, and percent change.
• ⚡ Bulk collection: collect up to a million rates in a single run, with automatic pagination handled for you.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with CoinCap data

📈 Build a crypto watchlist.

A trader supplies a list of currency IDs like btc, eth, and sol, runs the Actor every five minutes, and feeds the USD price and 24-hour change into a trading dashboard.

💹 Track fiat exchange rates.

A financial analyst sets the rate type to fiat, collects all major and minor currency pairs against USD, and loads the CSV into a spreadsheet for cross-rate calculations.

🥇 Monitor commodity prices.

A researcher filters by commodity type to pull gold and silver spot prices alongside their market caps, then compares them against crypto volatility.

📊 Populate a multi-asset database.

A data engineer schedules daily runs pulling all rates, normalizes the flat rows, and inserts them into a PostgreSQL warehouse for historical trend analysis.

Configure the run

Drive the Actor by asset class or a list of specific currency IDs, and the filter runs before collection so only matching rates land in your dataset. The Input tab lists every parameter.

A first run with the defaults:

{
 "maxItems": 10,
 "rateType": "all"
}

A larger pull:

{
 "maxItems": 200,
 "rateType": "all"
}

Troubleshooting

Why am I getting fewer results than my maxItems setting?

CoinCap lists a finite number of assets. If you set maxItems to 10,000 but only 2,000 crypto assets exist, you will receive 2,000 rows. Lower your maxItems or broaden your filter.

Why are some currency IDs not returning data?

Check that the ID is spelled correctly and exists on CoinCap. IDs are lowercase with no spaces, like bitcoin or ethereum. An invalid ID is silently skipped by the API.

Why does my commodity filter only return gold and silver?

CoinCap currently tracks only gold and silver under the commodity category. Other precious metals or commodities are not available through this endpoint.

Why is the 24-hour change field sometimes null?

Newly listed assets or those with extremely low volume may not have a calculable 24-hour change. This is data from CoinCap, not an error in the Actor.

Why did my run time out?

Requesting a very large number of rates with a short timeout can cause this. Increase the run timeout in the Actor's settings, or reduce maxItems.
