aid: usergems url: https://raw.githubusercontent.com/api-evangelist/usergems/refs/heads/main/apis.yml name: UserGems description: >- UserGems is a San Francisco-based sales intelligence platform that tracks champion job changes and surfaces buying signals so sales and marketing teams can prioritize outbound and ABM motions. The platform packages 30+ native signals (job changes, contact-level intent, M&A, hiring, web visits), Gem-E AI agents for prospect list building and email personalization, and custom AI scoring trained on 600+ closed-won patterns. UserGems exposes a public REST API at api.usergems.com/v1 that lets customers programmatically add and remove contacts to track for job changes, add and remove target accounts, and honor data-subject deletion requests. The API uses an X-Api-Key header for authentication and processes submissions asynchronously. Native integrations include Salesforce, HubSpot, Microsoft Dynamics, Outreach, Salesloft, Gong Engage, Marketo, LinkedIn Ads, Meta Ads, and Google Ads. tags: - Sales Intelligence - Outbound - ABM - Champion Tracking - Job Changes - Buying Signals - AI Scoring - Sales Engagement - CRM - Revenue Operations - GTM kind: contract image: https://kinlane-productions2.s3.amazonaws.com/apis-json/apis-json-logo.jpg access: 3rd-Party position: Consuming created: '2026-05-25' modified: '2026-05-25' specificationVersion: '0.16' apis: - aid: usergems:usergems-api name: UserGems API humanURL: https://app.usergems.com/api/documentation tags: - Sales Intelligence - Contacts - Accounts - Privacy description: >- The UserGems outbound REST API lets customers programmatically add and remove contacts UserGems should track for job changes, add and remove target accounts to source prospects against, and submit data-subject deletion requests.
