7 toolsexplain_standardExplain a certification or standardRead-onlyInspect
What a standard (AS9100D, NADCAP, ECSS, ISO 9001, MIL-STD …) certifies, why a buyer cares, what it is typically required for, and which suppliers in the index claim it.
| Name | Required | Description | Default |
|---|---|---|---|
| standard | Yes |
get_partGet a part with all specificationsRead-onlyInspect
All specifications for one part, whether the manufacturer confirmed them, and the supplier.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes | Part id from a search result |
get_supplierGet a supplier profileRead-onlyInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| slug | Yes | Supplier slug from a search result |
list_categoriesList part categoriesRead-onlyInspect
The part tree (segment → assembly → component) with supplier counts. Use to see what the index covers and where it has gaps.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
request_quoteRequest a quote from matching suppliersInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| nda | No | true if the user will only share drawings after suppliers sign an NDA | |
| consent | Yes | true only if the user explicitly agreed to share this request and their email with suppliers | |
| part_id | No | ||
| quantity | No | ||
| needed_by | No | Date or lead time | |
| buyer_name | No | ||
| buyer_email | Yes | The user's work email, as they gave it | |
| requirement | Yes | What is needed: part, specification, material, tolerance, certification, drawings available | |
| buyer_company | No | ||
| buyer_country | No | ||
| supplier_slug | No | ||
| export_controlled | No | ITAR/EAR or similar |
search_partsSearch parts by name or specificationRead-onlyInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | ||
| query | Yes | e.g. "3000 psi needle valve", "space heat pipe", "vacuum furnace 1250 C" | |
| confirmed_only | No | Only parts whose data the manufacturer confirmed |
search_suppliersSearch suppliers by capabilityRead-onlyInspect
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.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | ||
| query | No | Free text over name, description, capabilities and categories | |
| country | No | e.g. "India", "United Kingdom", "USA" | |
| certification | No | e.g. "AS9100D", "NADCAP", "ISO 9001" |
