get_part

All specifications for one part, whether the manufacturer confirmed them, and the supplier.

read-only

Argument	Type	Description
id*	integer	Part id from a search result

Input schema (JSON)

    }
  }
}

get_supplier

Full profile: what they make, capabilities (process, tolerance, envelope, material, lead time), certifications claimed, categories and products. Contact details are not returned — use the profile URL.

read-only

Argument	Type	Description
slug*	string	Supplier slug from a search result

Input schema (JSON)

    }
  }
}

list_categories

The part tree (segment → assembly → component) with supplier counts. Use to see what the index covers and where it has gaps.

request_quote

Send a quote request to whobuildsit, which reviews it and passes it to suppliers who can make the part. Before calling, ASK THE USER for their work email and explicit consent to share the request and email with suppliers — never invent an email. Give a part_id or supplier_slug from earlier results when you have one. Suppliers reply to the user directly; nothing is sent automatically.

Argument	Type	Description
nda	boolean	true if the user will only share drawings after suppliers sign an NDA
consent*	boolean	true only if the user explicitly agreed to share this request and their email with suppliers
part_id	integer
quantity	string
needed_by	string	Date or lead time
buyer_name	string
buyer_email*	string	The user's work email, as they gave it
requirement*	string	What is needed: part, specification, material, tolerance, certification, drawings available
buyer_company

search_parts

Find parts by keyword and/or numeric specification. Units are understood: "3000 psi" also matches parts rated in bar; "Ø40 mm", "1250 °C", "10 GHz" work. Returns matching parts with supplier, key specs and a URL.

read-only

Argument	Type	Description
limit	integer
query*	string	e.g. "3000 psi needle valve", "space heat pipe", "vacuum furnace 1250 C"
confirmed_only	boolean	Only parts whose data the manufacturer confirmed

Input schema (JSON)

{
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "limit": {
      "type": "integer",
      "default": 10,
      "maximum": 50,
      "minimum": 1
    },
    "query": {
      "type": "string",
      "description": "e.g. \"3000 psi needle valve\", \"space heat pipe\", \"vacuum furnace 1250 C\""
    },
    "confirmed_only": {
      "type": "boolean",
      "description": "Only parts whose data the manufacturer confirmed"
    }
  }
}

search_suppliers

Find companies that can make something — by process (e.g. "5-axis machining", "vacuum brazing"), material, certification (e.g. "AS9100D"), category, or country. Most space hardware is made to drawing by contract manufacturers that have no product catalogue; this is how to find them.

read-only

Argument	Type	Description
limit	integer
query	string	Free text over name, description, capabilities and categories
country	string	e.g. "India", "United Kingdom", "USA"
certification	string	e.g. "AS9100D", "NADCAP", "ISO 9001"
