Plans & Quotas
Every account is on a plan — the free sandbox tier by default, or paid pro, warehouse, scale. The plan controls several independent limits.
What a Plan Controls#
| Limit | What it bounds |
|---|---|
| Monthly render volume | How many labels you can render per billing period. |
| Monthly synthesis quota | How many synthesize calls you can make per period. |
| Rate limit & concurrency | Requests/sec and how many renders may be in flight at once. |
| DPI ceiling | The maximum target_dpi you may request. |
| API-key cap | How many active keys your tenant may hold. |
| Retention window | How long signed URLs to rendered PNGs stay valid. |
Hitting a render or synthesis limit returns a 402-class response, often with an upgrade_url. The free sandbox tier is enough to integrate and test — full features, just lower volume; paid tiers lift the caps. Enterprise is operator/contract-only and not self-serve.
