query parametric spec attributes for parts and filter search results by an attribute value

Steps
Authenticate via the client-credentials flow against https://identity.nexar.com/connect/token to get a supply.domain-scoped bearer token.
POST to https://api.nexar.com/graphql: supSearchMpn(q:"<mpn>", limit:5) { results { part { mpn specs { attribute { name id shortname } displayValue value unitsName unitsSymbol } } } } to retrieve technical specs.
Filter results by a specific attribute using its shortname in the filters argument, e.g. filters: { case_package: ["SSOP"] } — filtering on attribute existence alone is not supported.
Look up available attribute short-names/IDs via supAttributes ({ supAttributes { id name unitsName } }).
Confirm exact filterable field names in the Nitro IDE Schema Reference / Voyager view at https://api.nexar.com/ui/voyager before building production filters, since undocumented filter keys fail silently.
Known gotchas
Not every component has every attribute — specs arrays can be empty per part, and you cannot filter on 'attribute exists'.
Filter keys use attribute shortnames (snake_case, e.g. case_package), not the human-readable name shown in displayValue.
supSearchMpn returns 10 parts by default; each returned part still counts against the account's part limit even if it lacks the filtered spec.
