First Resonance
First Resonance builds ION, a modern Factory Operating System (MES) for companies manufacturing complex hardware in aerospace, defense, robotics, medical devices, and clean energy. ION provides digital work instructions (Procedures and Runs), part and inventory traceability, mBOM/aBOM management, quality and compliance workflows, production scheduling (ION AutoPlan), and analytics. For developers, ION exposes a GraphQL API (api.buildwithion.com) secured with OAuth 2.0 client-credentials API keys, cursor-based (Relay) pagination, webhook subscriptions for realtime events, and a beta hosted MCP server so AI agents can operate the factory system. This profile was enriched from First Resonance's public developer manual.

The First Resonance catalog on APIs.io includes 1 event-driven AsyncAPI specification.
First Resonance’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, pricing, signup flow, and 23 more developer resources.
