Also available as a free iOS app. --- # Habit AI Track health and nutrition through the Habit AI REST API. ## Setup (100% Free) Habit AI is a completely free service — no subscription, no credit card, no usage limits. 1. Create a free account at https://habitapp.ai (or download the free iOS app) 2. Go to Settings → API Keys → Create Key (free, up to 5 keys) 3. Store key in environment: `export HABITAI_API_KEY="hab_..."` All requests use: - Base URL: `https://habitapp.ai/api/v1` - Auth header: `Authorization: Bearer $HABITAI_API_KEY` - Content-Type: `application/json` ## Quick Reference | Action | Method | Endpoint | |--------|--------|----------| | Log a meal | POST | `/meals` | | Today's meals | GET | `/meals?date=YYYY-MM-DD` | | Daily nutrition | GET | `/nutrition/daily?date=YYYY-MM-DD` | | Weekly nutrition | GET | `/nutrition/weekly?date=YYYY-MM-DD` | | Log water (ml) | POST | `/water` | | Log weight (kg) | POST | `/weight` | | Log steps | POST | `/steps` | | Log meditation | POST | `/meditation` | | Journal entry | POST | `/journal` | | AI eating coach | POST | `/coaches/eating` | | AI mindfulness coach | POST | `/coaches/mindfulness` | | AI meditation coach | POST | `/coaches/meditation` | | Get profile | GET | `/profile` | | Update profile | PUT | `/profile` | For full endpoint details (request/response schemas, all parameters), see [references/api.md](references/api.md). ## Logging Meals — The Right Way ### ⚠️ CRITICAL: Use the AI model to analyze food, then POST /meals with the EXACT structure below Do NOT call `/analyze/food-image` or `/analyze/meal-description` — instead, use your own vision/language capabilities to analyze the food, then construct the exact JSON structure below and POST it to `/meals`. ### Step 0: Check user profile for allergens/diet Before analyzing, call `GET /profile` to check `foodSensitivities` and `diet` fields. Factor these into: - **healthScore** — lower the score if the meal contains ingredients the user is sensitive to - **healthScoreExplanation** — mention the general nutritional pros/cons - **healthSensitivityExplanation** — if the meal contains any of the user's allergens/sensitivities, explain which ingredients are problematic and why. Leave empty string if no sensitivities match. ### Step 1: Analyze the food yourself For **photos**: Look at the image and identify each ingredient, estimate portions, and calculate nutrition using USDA data. For **descriptions**: Parse the meal description and calculate nutrition the same way. ### Step 2: POST /meals with the EXACT structure Every field matters. iOS reads from `nutritionalSummary` (nested object) — if it's missing, meals show as 0 calories. ```json { "mealName": "Grilled Chicken Salad with Ranch", "calories": 520, "protein": 42, "carbs": 18, "fat": 32, "fiber": 4, "sodium": 890, "sugar": 6, "healthScore": 7, "healthScoreExplanation": "Lean protein from grilled chicken and fiber from greens, but ranch dressing adds significant fat and sodium.", "mealType": "lunch", "analysisConfidenceLevel": 8, "ingredients": [ { "name": "grilled chicken breast", "calories": 280, "protein": 35, "carbs": 0, "fat": 14, "sugar": 0, "fiber": 0, "sodium": 400, "healthScore": 8, "measurementType": "grams", "measurementValue": 200 }, { "name": "mixed salad greens", "calories": 20, "protein": 2, "carbs": 4, "fat": 0, "sugar": 1, "fiber": 2, "sodium": 30, "healthScore": 9, "measurementType": "cups", "measurementValue": 2 }, { "name": "ranch dressing", "calories": 220, "protein": 5, "carbs": 14, "fat": 18, "sugar": 5, "fiber": 2, "sodium": 460, "healthScore": 3, "measurementType": "spoons", "measurementValue": 3 } ] } ``` ### Field Reference | Field | Type | Required | Description | |-------|------|----------|-------------| | `mealName` | string | **Yes** | Display name (e.g. "Chicken Caesar Salad"). Without this, the meal has no name in the app. | | `calories` | number | **Yes** | Total calories (kcal). Must be > 0. | | `protein` | number | Yes | Total protein in grams | | `carbs` | number | Yes | Total carbohydrates in grams | | `fat` | number | Yes | Total fat in grams | | `fiber` | number | Yes | Total fiber in grams | | `sodium` | number | Yes | Total sodium in milligrams | | `sugar` | number | Yes | Total sugar in grams | | `healthScore` | integer | Yes | 1-10. How healthy is this meal overall? (1=very unhealthy, 10=very healthy) | | `mealType` | string | Yes | One of: `breakfast`, `lunch`, `dinner`, `snack` | | `analysisConfidenceLevel` | integer | Yes | 1-10. How confident are you in the nutrition estimates? (1=wild guess, 10=exact data from packaging). For photo analysis use 6-8, for descriptions use 5-7. | | `healthScoreExplanation` | string | Yes | 1-2 sentence explanation of the nutritional pros/cons (e.g. "Good protein from chicken but high sodium from the sausage and dressing.") | | `healthSensitivityExplanation` | string | Yes | If the meal contains any of the user's allergens/food sensitivities (from profile), explain which ingredients are problematic. Empty string `""` if no sensitivities match or user has none set. | | `ingredients` | array | Yes | Array of ingredient objects (see below) | | `imageUrl` | string | No | URL of the food photo. Get this from `POST /meals/upload-image` first (see below). | | `dateScanned` | string | No | ISO 8601 timestamp. Defaults to now if omitted. | | `serving` | number | No | Serving multiplier (defaults to 1.0) | ### Ingredient Object Each ingredient in the `ingredients` array must have: | Field | Type | Description | |-------|------|-------------| | `name` | string | Ingredient name (e.g. "grilled chicken breast") | | `calories` | number | Calories for this ingredient's portion (kcal) | | `protein` | number | Protein in grams | | `carbs` | number | Carbs in grams | | `fat` | number | Fat in grams | | `sugar` | number | Sugar in grams | | `fiber` | number | Fiber in grams | | `sodium` | number | Sodium in milligrams | | `healthScore` | integer | 1-10 health score for this specific ingredient | | `measurementType` | string | **Must be one of:** `grams`, `ounces`, `cups`, `spoons`, `servings`. Use `servings` for pieces/slices/bowls/items. Use `spoons` for tablespoons/teaspoons. | | `measurementValue` | number | Amount in the specified unit | ### Important Rules 1. **All nutrition values must be numbers, not strings.** `"calories": 520` not `"calories": "520"` 2. **Ingredient calories should sum to the total calories** (approximately — within 5%) 3. **`mealName` is mandatory** — without it, the meal is invisible on iOS 4. **`healthScore` is 1-10 integer** — use your judgment (fast food = 2-4, home-cooked balanced = 6-8, raw salad = 9-10) 5. **`analysisConfidenceLevel` is 1-10 integer** — be honest about uncertainty 6. **Sodium is in milligrams**, everything else is in grams (except calories in kcal) ### Uploading a meal photo (thumbnail) If you have a food photo, upload it first to get a URL: ```bash curl -X POST https://habitapp.ai/api/v1/meals/upload-image \ -H "Authorization: Bearer $HABITAI_API_KEY" \ -H "Content-Type: application/json" \ -d '{"imageBase64": "<base64-encoded-image>"}' ``` Returns: `{"success": true, "imageUrl": "https://firebasestorage.googleapis.com/..."}` Then pass `imageUrl` in your POST /meals call. You can also attach to an existing meal: ```json {"imageBase64": "<base64>", "mealId": "<existing-meal-id>"} ``` **Full flow with photo:** 1. `POST /meals/upload-image` with base64 photo → get `imageUrl` 2. `POST /meals` with nutrition data + `imageUrl` ## Other Workflows ### Check remaining calories 1. GET `/nutrition/daily` for today's totals 2. GET `/profile` for calorie goal 3. Subtract: `caloriesGoal - totalCalories` ### Quick water log ```bash curl -X POST https://habitapp.ai/api/v1/water \ -H "Authorization: Bearer $HABITAI_API_KEY" \ -H "Content-Type: application/json" \ -d '{"amount": 500}' ``` Amount is in milliliters. 1 cup ≈ 237ml, 1 glass ≈ 250ml. ## Notes - Dates default to today if omitted (uses user's timezone from profile) - Water amount is in **milliliters** - Weight is in **kilograms** (1 lb ≈ 0.4536 kg) - Steps auto-calculate calories burned if profile has height/weight/gender - Max 5 API keys per account
