Rocket Validator usage is measured in credits.

## Initial Credits

Just for signing up, you're granted **100 credits** to start validating your sites.

## Cost per Action

Credits are deducted when Rocket Validator successfully runs a validation engine or uses a paid option for one of your pages. Each validation engine is charged independently, so you can choose the coverage that fits your report.

| Action | Cost |
|---|---|
| W3C Nu HTML validation | 1 credit per checked page |
| Axe Core accessibility validation | 1 credit per checked page |
| AccessLint Core accessibility validation | 1 credit per checked page |
| Dynamic crawling | 1 credit per successfully crawled page |
| Store screenshots | 1 credit per stored screenshot |

The default Static Crawler is free. Storing raw results does not add a separate cost: the engine run that produced the result is the only charged action. Failed validations are not charged.

## Examples

### One Engine

Let’s say you validate a site with 100 web pages and enable only one engine — W3C Nu, Axe Core, or AccessLint Core. We’ll perform 100 checks, resulting in a total cost of **100 credits**.

### All Three Engines

If you validate a site with 100 web pages and enable W3C Nu, Axe Core, and AccessLint Core, we’ll perform 300 checks: one per engine for each page. The total cost is **300 credits**.

### Store Screenshots

If you store screenshots for a 100-page report, storing those images costs **100 additional credits** — one for every screenshot successfully stored. This is separate from the credits for any engines you enable.

### Dynamic Crawling

By default, we discover links using the free Static Crawler. As an advanced option, you can enable the [Dynamic Crawler](https://rocketvalidator.com/blog/dynamic-crawler-for-javascript-sites), which renders pages using JavaScript to find internal links. Dynamic Crawler usage costs **1 credit per crawled page**.

- If all pages are linked from the starting URL, only 1 dynamic crawl may be needed — costing **1 extra credit**.
- In the worst case (e.g., only one link per page), up to 100 dynamic crawls may be needed — costing **100 extra credits**.

### Raw Results Storage

By default, we don’t store raw results from the validation engines. As an advanced option via the API, you can enable storage of [raw checks](https://rocketvalidator.com/docs/api/raw_checks).

Raw storage does **not** use extra credits. You are charged only for the engine run that produced each raw result.

## Credit Exhaustion

If you run out of credits, you won’t be able to request additional validations until your credits are recharged.

## Credit Recharge

Credits can be recharged in two ways: by subscribing to a plan or by using a guest account.

### Subscription Plans

Subscribing to a plan is the easiest way to recharge your account periodically.

Check the [pricing page](https://rocketvalidator.com/pricing) to choose the subscription plan that best suits your needs.

Credits are recharged on a **weekly or monthly basis**, depending on your plan.

### Guest Accounts

If you're a [guest](https://rocketvalidator.com/docs/guest-accounts) of another user, your credits will also be recharged **monthly**, up to your allowed quota.
