How plans work

Plans are per org. Each org has its own orgApiKey and device cap. Every call passes that key, so the API can enforce limits for you.

Device counts are based on unique deviceId values registered for an org via /api/v1/devices/register.

When you change plans through Stripe, your cap updates on the API – your agents don’t need a new binary.

Limits, billing & automation
  • At the cap, /devices/register returns status: "limit_reached" with your current plan, limit, and devicesUsed.
  • Existing devices keep validating; new ones are blocked until you upgrade or free up space.
  • Upgrades and cancellations are managed in Stripe. Plan changes show up in /usage and /billing/summary.
  • The API is safe for scripts, services, and AI tools to call directly, but you stay in control of orgs and devices.
