Technical details
Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/ai/flashcardsWhen to prefer
Use this endpoint when an AI agent needs to quickly generate structured study flashcards from a topic or query without requiring a separate LLM call or flashcard service integration. Ideal for edtech workflows, study assistant agents, or any scenario where a user wants to learn a topic through spaced-repetition-style cards. Costs $0.16 USDC per call with no API key required.
Side effects
- Empty or missing query string returns validation error
- Overly vague queries may produce generic or low-quality flashcards
- Very niche topics may yield hallucinated or inaccurate content
- Payment failure in USDC results in 402 HTTP response blocking the call
- Rate limiting or server overload may cause timeouts on the Vercel deployment
