For the latest information on brelovitug and to follow Mirum's work in chronic hepatitis delta virus and rare diseases, visit https://mirumpharma.com" successor_site: https://mirumpharma.com/ note: >- The company no longer exists as an independent entity. This profile documents a surface that is still live, not an ongoing developer program. site_teardown: date_observed: '2026-08-07' description: >- The corporate site was collapsed to a single page when the acquisition closed. What is interesting for this catalogue is that the teardown was PARTIAL and asymmetric — the marketing navigation was deleted while both the HTML post archive and the REST API were left fully intact. The API is now a strictly richer record of the company than the site it belongs to. removed: - {path: /about/, status: 404} - {path: /science/, status: 404} - {path: /pipeline/, status: 404} - {path: /news/, status: 404} - {path: /contact/, status: 404} - {path: /privacy-policy/, status: 404} surviving: - {path: /, status: 200, note: single acquisition-notice page} - {path: /wp-json/, status: 200, note: full REST route index, 372 routes} - {path: /wp-json/wp/v2/posts, status: 200, note: all 35 press releases with full bodies} - {path: /wp-json/wp/v2/media, status: 200, note: 99-item media library incl. press-release PDFs} - {path: /category/press-releases/, status: 200, note: HTML category archive still browsable} - {path: /category/publication/, status: 200} - {path: /feed/, status: 200, note: RSS feed still serving 10 most recent items} - {path: /sitemap.xml, status: 200, note: sitemap index still generated, lists all 35 posts} - {path: /post-sitemap.xml, status: 200, note: 35 URLs} individual_permalinks: >- Verified still resolving — e.g. the December 2025 acquisition release returns 200 at its original slug. The archive was not redirected to the acquirer; it was simply left in place. versioning: scheme: uri-path-namespace current: wp/v2 docs: https://developer.wordpress.org/rest-api/ provider_policy: none detail: >- Versioning is inherited from WordPress core and its plugins. Bluejay Therapeutics never published a versioning policy of its own, and with the company absorbed there is no party maintaining one. deprecation: policy_url: null policy_published: false sunset_header: false deprecation_header: false deprecated_operations: [] detail: >- No deprecation policy, no RFC 8594 Sunset header, no Deprecation header, and no announced end of life for this surface. This is the material lifecycle risk for any consumer: the surface belongs to a company that has been fully absorbed, its content is frozen (newest post 2025-12-08, newest page 2026-01-26), and it can be switched off or redirected to the acquirer at any time with no notice mechanism in place. No `Deprecation` pointer is emitted — there is no policy to point at. status_page: url: null published: false detail: >- No status page. status.bluejaytx.com does not resolve, and no status or uptime page is linked anywhere on the site. No `StatusPage` pointer is emitted. sla: url: null published: false uptime_target: null support: channel: null detail: >- No support channel for this surface, and none for the company either — the /contact/ page was removed in the teardown and the Contact Form 7 API returns 403 to anonymous callers. Any enquiry now belongs to the acquirer at https://mirumpharma.com/. No `Support` pointer is emitted. changelog: url: null published: false detail: >- No API changelog. The provider's press-release archive is dated and chronological but it documents clinical and corporate milestones, not API changes, so it is catalogued as Blog/ BlogRSS rather than as a ChangeLog. No `ChangeLog` pointer is emitted. content_freshness: newest_post: '2025-12-08' oldest_post: '2021-08-12' post_count: 35 newest_page_modified: '2026-01-26' newest_media: '2026-01-26' assessment: >- Frozen. Nothing has been published through this API in the eight months since the acquisition closed. Treat the dataset as a closed historical archive. infrastructure: host: WP Engine (nginx) cms: WordPress notable_plugins_registered: - All in One SEO (aioseo/v1) - Elementor / Elementor Pro / Elementor AI - Contact Form 7 - MonsterInsights - Jupiter X theme (jupiterx-license) - OptinMonster (omapp/v1) - Code Snippets - WP Engine cache + sign-on plugins - WordPress Abilities API (wp-abilities/v1) observation: >- The plugin surface is still fully registered and, by implication, still being updated by someone. A wound-down site running Elementor, Contact Form 7 and an SEO suite is a maintenance obligation nobody has formally taken ownership of; it is also why the wp-abilities/v1 agent registry appeared here at all. x-evidence: fetched: '2026-08-07' probes: - {url: 'https://bluejaytx.com/', status: 200} - {url: 'https://bluejaytx.com/about/', status: 404} - {url: 'https://bluejaytx.com/science/', status: 404} - {url: 'https://bluejaytx.com/pipeline/', status: 404} - {url: 'https://bluejaytx.com/news/', status: 404} - {url: 'https://bluejaytx.com/contact/', status: 404} - {url: 'https://bluejaytx.com/privacy-policy/', status: 404} - {url: 'https://bluejaytx.com/category/press-releases/', status: 200} - {url: 'https://bluejaytx.com/wp-json/wp/v2/posts?per_page=100', status: 200} - {url: 'https://bluejaytx.com/wp-json/wp/v2/pages', status: 200} - {url: 'https://bluejaytx.com/post-sitemap.xml', status: 200} - {url: 'https://status.bluejaytx.com/', status: 0, note: 'DNS does not resolve'}
