look up a part's lifecycle/obsolescence status via the nexar (octopart) graphql api
domain: nexar.com · 6 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Create a free account at nexar.com and create an 'Application' to obtain a client_id/client_secret in the Nexar dashboard.
Request an OAuth2 access token via POST https://identity.nexar.com/connect/token using client_credentials grant with your client_id/client_secret and scope=supply.domain.
Send GraphQL queries to https://api.nexar.com/graphql with header Authorization: Bearer <access_token>.
Query supSearchMpn(q: "<MPN>") requesting part { specs { attribute { shortname } displayValue } } to retrieve the 'lifecyclestatus' spec attribute (values include EOL, NRND, New, Obsolete, Production).
Optionally also request the 'manufacturerlifecyclestatus' attribute for the raw, unhomogenized status straight from the manufacturer.
Optionally add filters: { lifecyclestatus: "Obsolete" } to supSearchMpn to filter results server-side by status.
Known gotchas
'lifecyclestatus' is Nexar's homogenized value and can differ from 'manufacturerlifecyclestatus', the raw manufacturer value — don't conflate the two.
SiliconExpert and Accuris (formerly IHS Markit) also offer lifecycle data but are enterprise-sales-gated with no public self-serve API, unlike Nexar's free-signup GraphQL access.
Access tokens are valid for 24 hours and must be refreshed via the same client_credentials flow — there is no long-lived static API key.
