API

SaaS users can automate with API keys and /v1/* endpoints.

Self-hosted and white-label operators additionally use /admin/* endpoints with admin credentials.

For SaaS key usage examples, see:

• API Keys and API (SaaS)

For self-hosted/white-label API automation, use the OpenAPI contract:

• Interactive API reference
• OpenAPI specification (YAML)

For LLM-driven automation, use the repo skill and pass your instance domain as the base URL:

• LLM Skill: Kvasyr API

User API Authentication

Authorization: Bearer <api_key>

Admin API Authentication (Self-Hosted / White-Label)

X-Admin-Password: <admin_password>
