There is no live API key or rate-limited service. Instead, each dataset is published as static files: CSV downloads, JSON versions of the smaller tables at /datasets/ .json, a machine-readable catalog at /datasets/index.json and a Frictionless Data Package at /datasets/datapackage.json. Fetch them server-side and cache them; they change only when we refresh the data.

JSON files and machine-readable catalog

There is no rate-limited API to sign up for. The data is published as static files you can fetch and cache:

/datasets/index.json lists every dataset with its CSV and JSON URLs, columns, row count, update date, attribution text and the embed URLs.
/datasets/datapackage.json is a Frictionless Data Package descriptor for the CSVs (open it with the frictionless Python or JavaScript libraries).
/datasets/<id>.json holds the smaller tables as { columns: [...], rows: [[...]] } with the license and attribution inside each file. The three large daily series are CSV only.

Example (JavaScript)

const res = await fetch('https://growyourethereum.com/datasets/ethereum-supply-yearly.json')
const { columns, rows, attribution } = await res.json()
// columns: ["period","supply_start_eth","supply_end_eth","net_change_eth","supply_growth_pct"]
// Show the attribution string (or a link to the source page) wherever you display the data.

Example (Python)

import pandas as pd
df = pd.read_csv('https://growyourethereum.com/downloads/ethereum-price-history-yearly.csv', comment='#')
print(df[['year', 'close', 'change_pct']])

How to cite

Any reasonable credit works under CC BY 4.0. The simplest is the dataset name linked to its page, followed by “GrowYourEthereum, CC BY 4.0”. Each card above has plain-text, HTML and BibTeX versions; here is the general pattern:

FAQ

Can I use this Ethereum data in an article, paper or commercial product?

Yes. Every GrowYourEthereum table, chart, CSV and JSON file listed here is licensed under Creative Commons Attribution 4.0 (CC BY 4.0). You can copy, adapt and republish it for any purpose, including commercially, as long as you credit GrowYourEthereum and link to the source page or the license. Raw third-party feeds (Coinbase, ultrasound.money, growthepie, Farside) keep their own terms.

How do I cite a GrowYourEthereum dataset?

Use the ready-made citations on this page or in the “Cite this data” box on each data page. A short form is: GrowYourEthereum (2026). Ethereum Price History (Coinbase ETH-USD) [Data set]. https://growyourethereum.com/data/ethereum-price-history. CC BY 4.0. Online, link the dataset title to the source page.

Is there an API?

There is no live API key or rate-limited service. Instead, each dataset is published as static files: CSV downloads, JSON versions of the smaller tables at /datasets/<name>.json, a machine-readable catalog at /datasets/index.json and a Frictionless Data Package at /datasets/datapackage.json. Fetch them server-side and cache them; they change only when we refresh the data.

How often is the data updated?

Price, supply, ETF, L2 fee and ETH vs SOL data are refreshed monthly, and sooner after major events such as an Ethereum upgrade, an ETF launch or a fee change. Each dataset shows its last update date and coverage window. The embeddable L2 fee table loads live data on every view.

Can I embed these charts and tables on my site?

Yes. Copy an embed snippet below. Each widget is a lightweight iframe with no ads, no tracking pixels of its own and a visible credit line. Please keep the credit paragraph under the iframe: it is how the CC BY attribution is given.

I found an error. How do I report it?

Email tim@growyourethereum.com with the dataset, the row and the source you are comparing against. We publish corrections on the affected page and note the change date.
