Terms: credit and link

The API is free, including for commercial apps and websites, under the CC BY 4.0 licence. The one condition: wherever you show the data, show this credit with a visible link to silverprice.corgano.com:

<a href="https://silverprice.corgano.com/">Silver price data by Corgano</a>

Put it next to the price, chart or table, or on a sources page linked from it. In an app, put it on the screen that shows the data or in its About screen with a tappable link. Please don't mark the link nofollow or hide it.

Request limits

Per IP address: 10 requests a minute, 60 an hour and 500 a day. Every response has X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset headers; over the limit you get HTTP 429 with Retry-After.

Cache on your side: the live price changes about once a minute and daily closes once a day, so a website should fetch once and serve its own copy. Calling the API from every visitor's browser counts against each visitor's own limit, which is fine for small sites.

Need the whole history every day? Download the CSV file instead: it has no request limit.

Free silver price API: FAQ

Is there a free silver price API?

Yes. https://silverprice.corgano.com/api/v1/latest returns the live silver spot price as JSON with no key or sign-up, and /api/v1/history returns daily closes since 2000. It is free for personal and commercial use with a credit and a link to silverprice.corgano.com.

Do I need an API key?

No. Send a plain GET request. Responses allow cross-origin requests (CORS), so the API also works from JavaScript in the browser.

What are the limits?

Each IP address can make 10 requests a minute, 60 an hour and 500 a day. Over the limit you get HTTP 429 with a Retry-After header. Every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset headers.

What credit do I have to give?

Show "Silver price data by Corgano" with a link to https://silverprice.corgano.com/ near the price, chart or table, or on a sources page that is linked from it. The ready-made HTML is <a href="https://silverprice.corgano.com/">Silver price data by Corgano</a>.

How often does the price update?

The live price updates about once a minute while the market is open; daily closes are added once a day after the 5 pm New York close. Polling more often than once a minute returns the same figures.

Can I use it in Google Sheets or Excel?

Use the CSV file https://silverprice.corgano.com/data/silver-price-history.csv with =IMPORTDATA() in Google Sheets or Data → From Web in Excel. It has no request limit; the API is for apps and websites.
