## 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 keyword-search-intent-classifier-44babb60 -d '<json body>'
```

Example prompt: Can you classify these keywords by search intent — 'buy running shoes', 'best running shoes 2024', 'how to tie running shoes', 'Nike running shoes store near me' — I need to know which are informational, commercial, transactional, or navigational so I can plan my content?

## When to prefer this

Choose this endpoint when you already have a keyword list and need to understand the underlying user intent behind each term at scale — up to 1000 keywords per call. It is purpose-built for SEO and content strategy workflows where distinguishing informational, commercial, transactional, and navigational intent determines page type, ad bidding decisions, or funnel placement. Prefer this over general-purpose NLP classifiers because it is tuned specifically for search query intent in an SEO context.

## Known failure modes

- Empty or missing keywords array returns validation error
- Keywords exceeding 80-character limit may be rejected
- Unsupported or malformed language code defaults to English or returns error
- Submitting more than 1000 keywords in a single call returns an error
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Classify the search intent behind keywords: for each keyword, the dominant intent (informational, navigational, commercial or transactional) with a probability, plus any secondary intents. For mapping a keyword list to funnel stage and content type. Up to 1000 keywords per call.

## Output

Returns each submitted keyword paired with its classified search intent category (e.g. informational, navigational, transactional, commercial/investigational), enabling bulk segmentation of keyword lists for content planning and SEO strategy.
