Frequently asked questions

Is there a free tier?

Yes. Run up to first 5,000 requests for free. You don't buy credits up front, and requests aren't billed per GB.

What happens when a request is blocked?

You don't pay for it. Billing only counts the requests that come back with content.

How is usage billed?

Per request, at per-1,000 rates that vary by plan and request type. On Starter ($20/month): Request · Standard $0.40, Request · Premium $4.00, Browser · Standard $2.00, Browser · Premium $8.00. On Growth ($100/month): Request · Standard $0.20, Request · Premium $2.00, Browser · Standard $1.00, Browser · Premium $4.00. Unused credits roll over.

How is the Browser WebSocket billed?

On bandwidth and duration rather than per request: $10.00 / GB and $0.12 / hr, the same on Starter and Growth.

What does the Enterprise plan include?

A custom rate card, volume-based pricing, and dedicated support, sized for high-volume workloads. Tell us what you're running and we'll scope it.
