FatSecret vs Calorie API
| FatSecret Platform | Calorie API | |
|---|---|---|
| Signup | Enterprise / partner | Self-serve instant |

Why Indie Devs Switch
Speed to first API call. Calorie API key in minutes vs procurement cycles.
Predictable pricing. Published tiers vs custom quotes.
Unified endpoints. Search, suggest, barcode, detail in one docs site.
Modern JSON. Per-100g macros map cleanly to mobile models.
FatSecret When It Still Fits
- Existing enterprise contract with FatSecret
- White-label partnership already signed
- Compliance requires approved vendor list including FatSecret
Integration Comparison
FatSecret historically uses OAuth 1.0a patterns. Calorie API:
curl "https://api.calorieapi.com/api/v1/search/foods?q=avocado" \
-H "X-API-Key: YOUR_KEY"
Proxy in production: secure Next.js route.
