FAQ

Billing questions, answered plainly

What counts as a request?

Any HTTP request that reaches a gateway route, including rejected 401/429 responses. Health probes and OPTIONS preflights are free.

Can I change plans mid-cycle?

Yes — upgrades apply immediately with pro-rated billing; downgrades apply at the next renewal. No lock-in on monthly plans.

Do you offer startup or non-profit pricing?

Yes. Registered startups under two years old get Standard at 50% for the first year. Charities get Business features at Standard pricing.

What happens if I exceed my included traffic?

Overage is billed per million requests at published rates, and you set a hard spend cap. We never surprise-invoice.

Need a plan shaped around your estate?

Enterprise agreements cover hybrid deployments, custom SLAs and residency requirements. Talk to engineering about what you actually need.
