Yes. Public read-only endpoints (no login needed) return posts and categories as JSON:

• GET /api/v1/blog/posts – latest posts (10 per page, with s for search and c for categories; the response includes a filters token to fetch the next page). Each post returns title, a full public URL, author, featured image URL, categories and creation date.
• GET /api/v1/blog/posts/{id} – one post; /related and /adjacents give related and previous/next posts. Note: this single-post response's url field is just the slug, not a full address.
• GET /api/v1/blog/categories – categories

Ask your developer to use these for headless/embedded blog feeds.
