March 2026
Welcome to the inaugural Horizon platform release notes. This March 2026 release marks the public launch of the Horizon API, developer documentation, and a collection of core platform features designed to give you full programmatic control over agents, skills, and workflows.
Horizon’s REST API is now available for programmatic access. Manage API keys, execute skills, query conversations, and more. The API follows RESTful conventions with JSON request and response bodies, standard HTTP status codes, and bearer-token authentication.
Agents can now be triggered via webhooks with IP allowlisting and token-based authentication. Configure inbound webhook URLs per agent, restrict traffic to trusted source IPs, and validate payloads using HMAC signatures for secure, event-driven automation.
Schedule agents to run on cron expressions with timezone support and automatic retry. Define recurring jobs using standard cron syntax, specify an IANA timezone for evaluation, and configure retry policies with exponential backoff for failed executions.
Full CRUD access to agent memory with working, episodic, and semantic memory types. Read and write to an agent’s memory layers programmatically, enabling external systems to seed context, extract learned knowledge, and manage memory lifecycle.
Improved async skill execution with BullMQ queuing and better error reporting. Long-running skills are now enqueued through BullMQ for reliable processing, and failed executions surface structured error details including step-level stack traces and retry metadata.
This documentation site is now live, covering the Platform Guide, Apps/Agents/Skills reference, and full API documentation. Browse conceptual overviews, follow step-by-step tutorials, and consult the complete API reference all in one place.
