Recipe Blog Nutrition Label Generator API

Food bloggers lose SEO when recipes lack nutrition labels. A recipe blog nutrition label generator API calculates calories and macros per serving from ingredient lists. Calorie API POST /calc/recipe resolves ingredients and returns label-ready totals.

See also TDEE and recipe calc features for endpoint details.

Blogger Workflow

1. Author enters ingredients ("2 cups flour", "3 eggs")
2. Your CMS calls Calorie API recipe calculator
3. Response returns calories, protein, carbs, fat per serving
4. Render nutrition label widget in post HTML
5. Update JSON-LD Recipe schema for SEO

Example Request

curl -X POST "https://api.calorieapi.com/api/v1/calc/recipe" \
  -H "X-API-Key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "servings": 4,
    "ingredients": [
      {"query": "chicken breast", "quantity": 500, "unit": "g"},
      {"query": "olive oil", "quantity": 1, "unit": "tbsp"}
    ]
  }'

SEO Benefits

• Rich results with nutrition in Recipe schema
• "Calories per serving" matches search intent
• Internal links to related recipes by macro range

WordPress Integration Pattern

$response = wp_remote_post($backend_url . '/api/recipe-nutrition', [
  'body' => json_encode(['ingredients' => $lines, 'servings' => 4]),
]);
$label = json_decode(wp_remote_retrieve_body($response));

Backend holds Calorie API key.
