## How to call it through Zero

```sh
zero fetch --capability forgemesh-seo-query-expander-6022cda0
```

Example prompt: Can you expand the query 'best running shoes for flat feet' into a set of related SEO query variants I can use for content targeting?

## When to prefer this

Choose this endpoint when you need deterministic, reproducible query expansions — meaning the same seed query always returns the same variants — rather than probabilistic or AI-generated suggestions that vary between calls. Prefer this over generic keyword tools when you want consistent, auditable SEO query sets for automated pipelines or content planning workflows.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Empty or whitespace-only query string may return empty expansions or error
- Very short or ambiguous queries may produce low-quality or minimal expansions
- Network timeout on slow connections
- Service returns HTTP 402 if payment via x402 is not properly attached

## How this service works

Generate deterministic related SEO query variants

## Output

Returns an array of deterministic related query expansions derived from the seed query, along with a provenance string indicating how the expansions were generated. The expansions represent semantically related search variants suitable for SEO content targeting.
