No other first-party packages were found in the registries checked (npm search API, direct npm lookups, PyPI, NuGet, RubyGems, crates.io). Direct lookups for @upollo/web and upollo on npm return 404, and pypi.org/pypi/upollo returns 404. The github.com/upollo organization exists but has no public repositories, and Upollo's primary domain upollo.ai no longer resolves (no A/NS/SOA/MX records), so the SDK documentation that previously lived there is unavailable. The remaining registry hits are third-party integration connectors, listed below. packages: - language: kotlin/java (android) registry: maven-central name: ai.upollo:upollo-android url: https://central.sonatype.com/artifact/ai.upollo/upollo-android install: 'implementation "ai.upollo:upollo-android:0.1.3"' official: true latest_version: 0.1.3 packaging: aar last_publish: '2022-12-15' third_party: - language: javascript registry: npm name: '@segment/analytics-browser-actions-upollo' url: https://www.npmjs.com/package/@segment/analytics-browser-actions-upollo official: false publisher: Segment (Twilio) last_publish: '2025-08-19' notes: Segment Analytics browser destination action for Upollo. - language: javascript registry: npm name: '@pipedream/upollo' url: https://www.npmjs.com/package/@pipedream/upollo official: false publisher: Pipedream last_publish: '2023-10-25' notes: Pipedream integration components for the Upollo API.
