# Value Catalog & Item Economics

This document explains how modpack authors can use the value catalog to balance retail pacing and merchandise economics.

***

## 1. Default Catalog & Elements Reference Table

Retail provides 35 balanced default item configuration seeds (managed via Fzzy Config):

| Item ID                          | Default Elements & Level                   | Cheap Band \[Stamp] | Perfect Band \[Stamp] | Expensive Band \[Stamp] | Overpriced Band \[Refusal] |

## 2. Value Container Progression

Cash registers utilize Value Containers (`value_container`) featuring a 5-tier upgrade ladder:

|    Tier    |      Capacity     | Upgrade Recipe Condition              | Emitted Light Level |
| :--------: | :---------------: | ------------------------------------- | :-----------------: |
| **Tier 0** |   `1,024` value   | Default recipe                        |        0 \~ 1       |
| **Tier 1** |   `4,096` value   | Upgrade full Tier 0 in crafting table |        1 \~ 2       |
| **Tier 2** |   `16,384` value  | Upgrade full Tier 1 in crafting table |        2 \~ 4       |
| **Tier 3** |   `65,536` value  | Upgrade full Tier 2 in crafting table |        4 \~ 5       |
| **Tier 4** |  `262,144` value  | Upgrade full Tier 3 in crafting table |        5 \~ 7       |
| **Tier 5** | `1,048,576` value | Upgrade full Tier 4 in crafting table |       8 (Max)       |

## 3. Four-Tier Pricing Model

Each entry declares four price bands:

* `cheap`: Substantially below market expectations. Triggers rapid purchases and boosts continuous purchase chances.
* `perfect`: Ideal fair market value. Standard trading balance.
* `expensive`: Elevated price. Accepted only by high-budget buyers.
* `overpriced`: Excessive price. Customers reject the item and leave the shop.

***

## 4. Competition & Item Data Matching

When multiple pedestals display the exact same item, customer AI prioritizes the lowest-priced pedestal. Item matching evaluates the complete item ID and data components (including enchantments, custom names, and NBT data).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://eurekabusiness.caiziii.com/eurekabusinesscommunity-en/pack-makers/catalog-and-economics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
