## Rule Type
Each price within a price set can be applied for different conditions. These conditions are represented as rule types.
A [RuleType](/references/pricing/models/RuleType) defines custom conditions. A rule type has a unique `rule_attribute` which indicates the property this rule applies on. For example, `region_id`.
This is referenced when setting a rule of a price. For example:
export const ruleTypeHighlights = [
["8", "region_id", "Reference a rule type by its `rule_attribute`."],
["8", `"PL"`, "The value of this rule."]
]
```ts highlights={ruleTypeHighlights}
const priceSet = await pricingModuleService.addPrices({
priceSetId,
prices: [
{
amount: 500,
currency_code: "EUR",
rules: {
region_id: "PL",
},
},
],
})
```

## Price List ## Price List
A [PriceList](/references/pricing/models/PriceList) is a group of prices only enabled if their conditions and rules are satisfied. A price list has optional `start_date` and `end_date` properties, which indicate the date range in which a price list can be applied.

The context is an object passed as a second parameter to the `calculatePrices` method. It must contain at least the `currency_code`. Only prices in the price sets with the same currency code are considered for the price selection. The calculation context is an optional object passed as a second parameter to the `calculatePrices` method. It accepts rules to restrict the selected prices in the price set.

## Price Rule ## Price Rule
Each rule of a price within a price set is represented by the [PriceRule data model](/references/pricing/models/PriceRule), which holds the value of a rule type. The `Price` data model has a `rules_count` property, which indicates how many rules, represented by `PriceRule`, are applied to the price. Prices can be restricted by rules.

For example, you create a `zip_code` rule type. Then, a price within the price set can have the rule value `10557`, indicating that the price can only be applied within the `10557` zip code. ![A diagram showcasing the relation between the PriceRule and Price](https://res.cloudinary.com/dza7lstvk/image/upload/v1709648772/Medusa%20Resources/price-rule-1_vy8bn9.jpg)
Each price within the price set can have different values for the same rule type. For exmaple, you create a price restricted to `10557` zip codes.
For example: A price can have multiple price rules. For example:

Each price can have multiple rules applied to it as well. For example, a price can be restricted by a region and a zip code.
For example, a price can have the rules `zip_code` and `region_id` applied to it. In this case, the value of each rule is represented by a `PriceRule`.

## Restrict Price Rules
The [PriceSetRuleType data model](/references/pricing/models/PriceSetRuleType) indicates what rules the prices can have within a price set. It creates a relation between the `PriceSet` and `RuleType` data models.
For example, to use the `zip_code` rule type on a price in a price set, the rule type must first be enabled on the price set through the `PriceSetRuleType`.
