Blogspot / Blogger Fetch Strategy

Blogspot pages are JS-rendered — WebFetch on the HTML page returns an empty shell. Use the Blogger JSON Feed API instead.

Feed URL Template

https://<blog>.blogspot.com/feeds/posts/default?alt=json&max-results=<n>

Parameters

Parameter	Description	Example
alt=json	Return JSON instead of Atom XML	Required
max-results	Number of posts to return (max 150)	max-results=50
start-index	1-based offset for pagination	start-index=51
published-min	Filter posts after this date (ISO)	published-min=2024-01-01T00:00:00
published-max	Filter posts before this date (ISO)	published-max=2024-12-31T23:59:59

Examples

Fetch latest 10 posts

WebFetch https://example.blogspot.com/feeds/posts/default?alt=json&max-results=10

Fetch posts from a specific date range

WebFetch https://example.blogspot.com/feeds/posts/default?alt=json&max-results=50&published-min=2024-06-01T00:00:00&published-max=2024-06-30T23:59:59

Paginate through all posts

First page:

WebFetch https://example.blogspot.com/feeds/posts/default?alt=json&max-results=50&start-index=1

Second page:

WebFetch https://example.blogspot.com/feeds/posts/default?alt=json&max-results=50&start-index=51

Response Structure

The JSON response has this shape:

feed.entry[]        — array of posts
  .title.$t         — post title
  .content.$t       — full HTML content
  .published.$t     — publish date (ISO 8601)
  .updated.$t       — last updated date
  .author[].name.$t — author name
  .link[]            — links (look for rel="alternate" for the post URL)

Key Points

• No headless browser needed — WebFetch alone is sufficient
• Works on any *.blogspot.com domain
• max-results caps at 150 per request; use start-index to paginate beyond that
• Date filters use ISO 8601 format
