OpenCal

OpenCal is a calorie & nutrition tracker with a beautiful iOS app. This skill lets your AI agent log meals, check progress, and update goals — so the user never has to open the app to track what they eat.

"I just had a burrito for lunch" → agent searches, scales, logs it → it shows up in the app instantly.

Setup

Download OpenCal from the App Store
Sign in and set your calorie/macro goals
Go to Profile → API Keys → Generate

Set the key:

export OPENCAL_API_KEY="sk_your-key-here"

When to use this skill

User says	What to do
"I had a chicken sandwich for lunch"	Search food → scale nutrition → log it
"What did I eat today?"	Fetch today's log and summarize
"How much protein do I have left?"	Fetch log totals and compare to goals
"I want to cut to 1800 calories"	Update their calorie goal
"That last entry was wrong, remove it"	Delete the log entry
"What's in a banana?"	Search and show nutrition info (don't log)

Log a meal

The most common flow. User says something like "I had 200g chicken breast for lunch":

1. Search for the food:

curl -s "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/food/search?q=chicken+breast&limit=5" \
  -H "Authorization: Bearer $OPENCAL_API_KEY" | jq '.results[] | {name, calories, protein, carbs, fat}'

Results are per 100g. Pick the best match.

2. Scale to the actual amount and log:

curl -s -X POST "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/food/log" \
  -H "Authorization: Bearer $OPENCAL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Chicken Breast",
    "amount": 200, "unit": "g",
    "calories": 330, "protein": 62, "carbs": 0, "fat": 7.2,
    "mealType": "lunch"
  }'

Multiply all nutrition values by amount / 100. The entry appears in the app immediately.

Use mealType: breakfast, lunch, dinner, or snack. Add "loggedAt": "2026-02-18T12:00:00Z" to backfill a past meal (defaults to now).

3. Confirm with the user: "Logged 200g chicken breast for lunch — 330 kcal, 62g protein."

Check daily progress

curl -s "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/food/log?date=2026-02-18" \
  -H "Authorization: Bearer $OPENCAL_API_KEY" | jq '{totals, entries: [.entries[] | {name, calories, mealType}]}'

Omit ?date= for today. Returns each entry plus totals (calories, protein, carbs, fat).

Check and update goals

# Current goals
curl -s "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/goals" \
  -H "Authorization: Bearer $OPENCAL_API_KEY" | jq

# Update (only include fields to change)
curl -s -X PUT "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/goals" \
  -H "Authorization: Bearer $OPENCAL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"calorieGoal": 1800, "proteinGrams": 160}'

Delete a log entry

Get the entry ID from the daily log, then:

curl -s -X DELETE "${OPENCAL_BASE_URL:-https://api.opencal.ai}/api/v1/food/log/{id}" \
  -H "Authorization: Bearer $OPENCAL_API_KEY"

Important notes

Search results are per 100g — always scale before logging
If the user doesn't mention an amount, ask — don't guess
If search returns nothing, try shorter/simpler terms (e.g. "rice" instead of "steamed jasmine rice")
Always confirm what you logged so the user can correct mistakes
