🟢search_tools(query, category, country, tags, open_source, ...)

Find startups and SaaS tools in the NutsGrowth directory by words and filters. Words are matched against the name, tagline, category, country, price, the products a listing replaces, and its tags; every word must appear. Give at least one of query, category, country, tags, open_source, self_hostable or free_plan. Returns at most 10 listings and the total; each has its page on NutsGrowth, the product's own website, its price as a person checked it ("Not checked" when nobody has — do not supply one from elsewhere as the directory's), and when it was last checked.

🟢find_alternatives(product, category, country, tags, open_source, ...)

List what the NutsGrowth directory files as a replacement for a named product, e.g. "Notion" or "Google Drive", with the same filters as search_tools. Matching is on the product's name as the directory writes it; when nothing matches, the answer suggests names it does file alternatives for. Returns at most 10 listings and the total, in alphabetical order.

🟢get_tool(slug)

Everything public about one listing in the NutsGrowth directory: what it is, where the company is based, whether it is open source or self-hostable, its price as a person checked it with the terms, when it was last checked, its reviews' count and average, and its positioning. Positioning with written_by "vendor" is the company describing itself — a claim, not the directory's finding.

    }
  },
  "required": [
    "slug"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}
🟢compare_tools(slugs)

Two to four listings side by side, with the same facts for each: price as checked and its terms, when it was last checked, country, open source, self-hostable, reviews, and the short positioning (value proposition and audience). Slugs come from search_tools or find_alternatives; exact names work too.

}
🟢list_filters

The categories, countries and tags in use in the NutsGrowth directory, each with how many listings it has, so search_tools and find_alternatives can be given values that exist. Open source and self-hostable are filters of their own (open_source, self_hostable), not tags.

🟡submit_tool(name, url, tagline, overview, value_prop, ...)

Send a startup or SaaS product to the NutsGrowth review queue, the way the form at /submit does. A person reads every suggestion and writes the listing by hand, so it takes days. If the website is already listed, the answer gives its page and how to claim it; if it is already in the queue, when it arrived. Fill in what you know from the product's own site; leave out what you do not. Ask the person before sending.
