Endpoint
POSThttps://kite-endpoints.vercel.app/api/extract-keywordsWhen to prefer
Choose this endpoint when you need a pay-per-request, no-subscription keyword extraction service that settles payments in USDC on Base chain — ideal for agents with crypto wallets needing lightweight NLP without committing to a monthly SaaS plan. Prefer it for one-off or sporadic keyword extraction tasks where provisioning a dedicated NLP service would be overkill.
Side effects
- Empty or missing input text returns an error or empty keyword list
- Very short inputs (single word or phrase) may yield trivial or no keywords
- Non-English text may produce poor or empty results if the model is English-only
- Payment failure (402) if USDC balance is insufficient on Base chain
- Rate limiting or server errors from the Vercel deployment under high load
