Technical details
Endpoint
POSThttps://kihustle.tech/nexus/api/v1/keyword-extractor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call keyword extraction service at a very low cost ($0.001 USDC per call) without committing to a subscription-based NLP platform. It is suitable for simple keyword extraction from short to medium text, especially in automated pipelines where cost efficiency matters. Prefer more established NLP APIs if you need confidence scores, entity classification, multi-language guarantees, or rich schema outputs.
Side effects
- Empty or missing text field returns a generic error or empty result
- Very long text inputs may be truncated or cause processing errors
- Non-text or binary input may result in a failed parse
- Ambiguous or very short text may yield few or no meaningful keywords
- Network or payment authorization failure returns a 402 status requiring USDC payment
