Got questions? We've got answers. Here's everything you need to know about Companin.
Most sites just paste the script. But if you're a SaaS or platform team, every part of Companin is available over a REST API — go from sandbox to production without rewriting your stack.
Generate an API key from the dashboard and authenticate every request with the X-API-Key header.
The REST API exposes every core resource: agents, knowledge, sessions, contexts, conversations, and analytics. Bring the agent experience into your applications without reimplementing the backend.
Create, update, and archive organization-specific agents with tone, language, and default task settings.
Manage files, curated Q&A, and URLs with summaries, keywords, and embeddings ready for semantic search.
Pull usage, request logs, and rate-limit signals straight from the API to feed your own dashboards and monitoring.
Export detailed API request logs to investigate issues and confirm compliance across organizations.
GET
/core/analytics/logs/Track volume by endpoint and organization to stay ahead of rate limits and plan billing.
