POSThttps://nexus-api-virid.vercel.app/api/ai/faqWhen to prefer
Choose this endpoint when you need a quick AI-generated answer to a natural language question, especially for FAQ-style queries, without needing to manage API keys. It is best suited for lightweight question-answering tasks where pay-per-call pricing in USDC is acceptable and no persistent session or complex reasoning chain is required.
Side effects
- Empty or missing query field results in a bad request error
- Vague or ambiguous queries may return low-quality or irrelevant answers
- Service unavailability on the Vercel deployment may cause 5xx errors
- Payment failure in USDC on Base will block access to the endpoint
- Queries outside the FAQ knowledge domain may return generic or hallucinated responses
