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#

LimitWhat it bounds
Monthly render volumeHow many labels you can render per billing period.
Monthly synthesis quotaHow many synthesize calls you can make per period.
Rate limit & concurrencyRequests/sec and how many renders may be in flight at once.
DPI ceilingThe maximum target_dpi you may request.
API-key capHow many active keys your tenant may hold.
Retention windowHow 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.

TipThe authoritative, always-current plan catalog is served by the API itself — do not hardcode numbers from docs. Read tier numbers from GET /v1/plans.
