Frequently asked questions
What does the monthly fee pay for?
Usage. Each month's fee is added to your balance in full, so $19 on Starter is $19 of requests. Requests draw down that balance at your plan's rates, and whatever you don't use rolls over. Prices as of October 2026, from the String pricing page (https://usestring.ai/pricing).
Can I buy credits without a subscription?
A plan is how you buy credit: there are no separate credit packs. Starter at $19/month puts $19 on your balance each month, unused credit never expires, and you can add funds or turn on auto top-up any time under Usage & Plans in the portal. Prices as of October 2026, from the String pricing page (https://usestring.ai/pricing).
Which requests am I charged for?
A request is billed when String gets the site's response back to you, whatever status the site sent. A 404 from the site is billed because it is the site's real answer. Blocked requests and errors on our side are free. Two exceptions are billed: a request with custom headers that the site blocks, and a request to a site with an invalid certificate.
What happens when my credit runs out?
The API stops serving requests until you add credit. Turn on auto top-up under Usage & Plans in the portal and your balance refills automatically at your plan's rates, so a production job never stalls.
When do I pay premium rates?
Only when a site blocks the standard proxy. String moves that request to a premium proxy and bills it at the premium rate. Sites that work on standard stay on standard.
Do credits expire? What if I cancel?
No. The $5 free credit never expires, and paid credit rolls over month to month. If you cancel, your remaining balance stays usable until you spend it. Prices as of October 2026, from the String pricing page (https://usestring.ai/pricing).
Do I need a card for the free credit?
No. Sign up and you get $5 of credit to use on any endpoint, and it never expires. Add a card when you pick a plan. Prices as of October 2026, from the String pricing page (https://usestring.ai/pricing).
Is there a concurrency limit?
Every plan runs up to 10,000 fetches and 5,000 browser sessions in parallel. Throughput is governed by your plan's request rate.
What does Enterprise include?
A custom rate card and request rate sized to your volume, priority support and incident resolution, and a DPA with security review. Agreements start at $2,500 a month. Tell us what you're running and we'll scope it. Prices as of October 2026, from the String pricing page (https://usestring.ai/pricing).
