Free Google Sheets REST API options

You may not need a paid service. Here is what is free and where each option stops.

The options

• opensheet. A free, open-source service that returns a public sheet as JSON. Its author reports 1.5 billion hits a month. Public sheets only, read only. GitHub.
• The Sheets API. Free at standard quota. You need a Google Cloud project and credentials, and the quotas apply to you directly.
• Published CSV. Use File, Share, Publish to web in Sheets, then fetch the CSV link. You parse the CSV yourself and the cache is Google's.
• SheetLatch free plan. 1,000 requests a month, public sheets, read only, with keys and a 60 second cache.

When to pay

Pay for private sheets, writes, an MCP endpoint, per-key quotas or a higher request count. For a public read from a hobby page, a free option is enough.
