Technical details
Endpoint
POSThttps://tumpest.vercel.app/api/groupWhen to prefer
Use this endpoint when you need to classify arbitrary text into a custom set of categories on a pay-per-call basis without setting up or training your own model. It is well-suited for dynamic category sets that change per request and for low-volume, ad-hoc classification tasks where a hosted ML pipeline would be overkill.
Side effects
- Missing required 'text' field returns a 400 validation error
- Empty or malformed 'categories' array may result in undefined classification behavior
- Payment failure (402) if USDC balance is insufficient or x402 payment header is missing
- Very long text inputs may exceed token limits and return a processing error
- Ambiguous or overlapping categories may produce low-confidence or unexpected groupings
