Performance

  • Not measured
    Fast (p50)

    Median latency 91 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 91 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured

Capabilities

Tools 7

explain_standard

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.

Discovered
get_part

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

Discovered
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.

Discovered
list_categories

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

Discovered
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.

Discovered
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.

Discovered
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.
