“A customer just left a brief review saying 'great customer service, fast shipping'. Can you expand that feedback into a more detailed description so I can better understand what went right?”

Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/ai/expand?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to take a short query, keyword, or phrase and have an AI model elaborate or expand it into richer, longer-form content. Useful for content generation pipelines, ideation, or enriching sparse data. Best suited for single-call, pay-per-use AI text expansion without API key management.
Side effects
- Empty or missing query field returns a validation error
- Query too long or malformed may result in an API error
- Payment failure in USDC on Base causes a 402 response and no content returned
- Vague or ambiguous queries may produce generic or low-quality expansions
- Service downtime on Vercel hosting returns 5xx errors
