How billing works

Simple, usage-based credits. You only pay for results you actually get back.

01

Pay for returned results

Web search costs 1 credit per 10 returned result positions, rounded up. Up to 10 results cost 1 credit; 30 cost 3.

02

No charge for errors

Failed requests and empty result pages cost nothing. You only spend credits when results are returned.

03

Keep your unused credits

Buy credits as needed. Purchased credits never expire, with no monthly reset or automatic renewal.

Pricing questions

What is a credit?

A credit is the billing unit across OpenSERP Cloud. For single-engine web search, billing is 1 credit per 10 returned result positions, rounded up - so a default search (up to 10 results) is 1 credit and a deep search returning 53 results is 6. This is result count, not query count. Image search, extraction, and balanced megasearch use dynamic pricing.

Do failed requests cost credits?

No. Errors, timeouts, and empty result pages are never charged. You only spend credits on successful responses with real data.

Is there a subscription or minimum?

Neither. Credits are pay-as-you-go with no recurring fee and no minimum spend. Start with a few dollars and scale when you need to.

Do credits expire?

No. Purchased credits never expire. Top up once and draw down at your own pace with no monthly reset and no surprise renewals.

Are the free credits recurring?

No. The 60 free credits are a one-time grant for new accounts. After they run out you top up and pay per search, with no subscription and no monthly reset.

How do I pay?

Top up your balance from the dashboard. Credits are added the moment your payment confirms and never expire.

No card to start. Card payments run through Stripe; crypto is available from the dashboard.
