Recommendation APIs
Personalised product, content and next-item recommendations as a service.
What it is
Recommendation APIs learn from your catalogue and user interactions (views, clicks, purchases) and return ranked items for a user or item: 'recommended for you', 'frequently bought together', 'similar items'. They replace building and operating your own recommender system.
How pricing works
Typically per 1,000 real-time recommendation requests, plus data ingestion and training charges and sometimes a minimum throughput commitment. We normalise to the per-request price at light volume; ingestion, training and minimum-capacity charges are shown in the description where known.
We compare everything in one unit: USD per 1K recommendation requests.
Typical uses
- E-commerce product carousels and cart cross-sell
- Media and content feeds
- Personalised emails and push notifications
- Search result personalisation
What to compare
- Lift in click-through or conversion in A/B tests
- Cold-start handling for new users and items
- Real-time updating from live events
- Business rules and merchandising controls
- Latency
Watch out for
- Training and minimum-throughput charges can dominate at low traffic; model the full monthly cost.
- Results are only as good as your event data; plan instrumentation first.
- Check explainability and fairness requirements for regulated content.
