When to use this skill
When the user asks about a fruit's nutrition — calories, sugar, fat, carbs, protein per serving — or its botanical classification (family, genus, order). Fruityvice covers 49 common fruits with unauthenticated GET requests. For vitamins, minerals, fiber, or anything beyond macronutrients, this is the wrong skill.
Your best first call
curl "https://www.fruityvice.com/api/fruit/durian"
No auth. No key. Returns a single JSON object. Use /fruit/{name} when you have a fruit name (case-insensitive), /fruit/{id} when you have a numeric ID, and /fruit/all only when you need the full list.
Key fields:
name — common fruit nameid — numeric identifierfamily, order, genus — botanical classification (mind the Kiwi bug in Pitfalls)nutritions.calories — kcal per servingnutritions.fat, nutritions.sugar, nutritions.carbohydrates, nutritions.protein — grams per serving
Durian is worth calling first because it's the outlier: 147 kcal and 5.3g fat — the fattiest fruit in the dataset by a wide margin. Most fruits sit under 0.5g fat.
Fallbacks (when the best call isn't enough)
- Need to compare or rank fruits by nutrition →
/fruit/all returns all 49 fruits. Fetch once, index by name, and filter client-side. No server-side search or filtering exists.
Pitfalls
- The Kiwi entry (
id: 66) conflates the bird and the fruit: order is "Struthioniformes" and genus is "Apteryx" — both are the kiwi bird, not the kiwi fruit. family correctly says "Actinidiaceae". Do not trust order or genus for this one record.
- Only five nutrition fields (calories, fat, sugar, carbohydrates, protein). No vitamins, minerals, fiber, or water content. If the user asks about vitamin C in an orange, Fruityvice cannot answer.
- The
name path parameter must match a complete fruit name — partial strings return 404. "Apple" works; "app" does not.
One-line summary for the user
I can look up nutrition data — calories, sugar, fat, carbs, protein — and botanical classification for any of 49 fruits from Fruityvice, no API key required.

## Your best first call
```bash
curl "https://www.fruityvice.com/api/fruit/durian"
```
No auth. No key. Returns a single JSON object. Use `/fruit/{name}` when you have a fruit name (case-insensitive), `/fruit/{id}` when you have a numeric ID, and `/fruit/all` only when you need the full list.
Key fields:
- `name` — common fruit name
- `id` — numeric identifier
- `family`, `order`, `genus` — botanical classification (mind the Kiwi bug in Pitfalls)
- `nutritions.calories` — kcal per serving
- `nutritions.fat`, `nutritions.sugar`, `nutritions.carbohydrates`, `nutritions.protein` — grams per serving
Durian is worth calling first because it's the outlier: 147 kcal and 5.3g fat — the fattiest fruit in the dataset by a wide margin. Most fruits sit under 0.5g fat.
## Fallbacks (when the best call isn't enough)
- **Need to compare or rank fruits by nutrition** → `/fruit/all` returns all 49 fruits. Fetch once, index by `name`, and filter client-side. No server-side search or filtering exists.
