## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kiteendpoints-ai-extract-keywords-a76e1643 -d '<json body>'
```

Example prompt: Can you extract the main keywords from this article text for me: 'Artificial intelligence is transforming healthcare by enabling faster diagnosis, personalized treatment plans, and predictive analytics that save lives'?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns a structured object containing an array of extracted keywords or key phrases drawn from the input text, suitable for use in tagging, SEO, topic modeling, or content categorization pipelines.
