Gods Unchained API

Public developer API documentation for Gods Unchained, a trading card game on the Ethereum blockchain.

This version of the API (v0) is in a limited public beta: if you discover a bug, or the api returns results contrary to the specification, report it here. Error specifications will be added soon.

Projects

Here are some third-party tools built using these APIs, make sure to ask in our Discord server if you're looking for help or you're wondering what to build.

GUDecks

General

Base URL

The base url for all requests is:

https://api.godsunchained.com

This URL must be suffixed with the version being requested (current version: v0).

https://api.godsunchained.com/v0/

Duplicate Arguments

We support queries of the following form:

https://api.godsunchained.com/v0/card?god=nature&god=death

Duplicate argument keys will be interpreted disjunctively: this query will return cards where the god is either nature OR death.

Pagination

All requests which can return multiple objects can be shaped by the page and perPage parameters.

https://api.godsunchained.com/v0/proto?page=3&perPage=20

All paginated endpoints return data in the following format:

{
    total: number
    page: number
    perPage: number
    records: Array<any>
}

Where total is the number of records discovered by this query.

Sorting

Sorts are applied to paginated endpoints using the sort and order query parameters:

https://api.godsunchained.com/v0/card?sort=mana&order=asc

Range and number types can be ordered by order=asc and order=desc, defaulting to asc.

Multiple sort parameters can be applied in one query, and will be applied in order:

https://api.godsunchained.com/v0/card?sort=mana&order=asc&sort=health&order=desc

For queries without exact pairings of sort and order parameters (where multiple parameters are applied), it is necessary to mark the order as null:

https://api.godsunchained.com/v0/card?sort=mana&order=asc&sort=god&order=null&sort=health&order=desc

Rate Limits

Currently, there is a rate limit of 5 per second (5/s) on all endpoints. This may change in the future.

Types

General types:

Type	Description
	A url encoded string.
	A decimal number.
	`true` or `false`

Custom API types:

Type	Description
	A hexadecimal Ethereum address, case insensitive.
	A specific number `1000`, a range `1000-2000`, a minimum `1000-` or a maximum `-2000`.

The valid options for the enumeration types in various apis are set out below:

Type	Options
	light, death, nature, war, magic, deception
	rare, epic, legendary, shiny
	common, rare, epic, legendary, mythic
	creature, spell, weapon
	nether, aether, atlantean, viking, olympian, anubian, amazon
	plain, shadow, gold, diamond
	full, card

Concepts

There are several 'types' of card in Gods Unchained:

Token: A full ERC721 token card which has been 'activated'.
Model: The most common type of card: locked in, shown on frontend, but not yet converted to an ERC721 token to save gas.
Centralized: Cards which cannot be traded on the blockchain (part of the core set or an untradeable promotion card).

Some of these endpoints return a combination of the above, while some do not: this is documented by the individual endpoints. In general, the default is to return only cards which can become ERC721 tokens (i.e. Token and Model cards).

Prototype cards, or protos, contain the underlying stats for a class of card.

Helper APIs
