API Overview

In addition to an instant marketplace for ERC721-based items, OpenSea provides an HTTP API for fetching non-fungible ERC721 assets based on a set of query parameters. Monitoring every ERC721 contract and caching metadata for each individual token can be a lot of overhead for wallets and websites that wish to display all of a user's collectibles, gaming items, and other assets. By aggregating this data in an easy-to-consume API, we make it easy for wallets and other sites.

Here are a couple of products that have integrated the OpenSea API:
Coinbase Wallet
3Box
Opera Wallet
Trust Wallet
Editional
Balance
CryptoGoods
ToknTalk
CKBox
Vault Wallet
Bitski
Portis
Amberdata
Go Wallet
Pillar Wallet
ReceiptChain
imToken
Rainbow

We provide this API free of charge, but ask in return that you give credit to OpenSea on your site, and link to the OpenSea marketplace from the assets you display (where appropriate). Please see our Logos & Brand Guidelines for images that you can use to credit OpenSea.

This API is rate-limited. If you'd like to use it in a production environment, request an API key here.

Asset Object

The primary object in the OpenSea API is the asset, which represents a unique digital item whose ownership is managed by the blockchain. The below CryptoSaga hero is an example of an asset shown on OpenSea.

Here's an overview of some of the fields contained in an asset:

Field name

Description

token_id

The token ID of the ERC721 asset

image_url

An image for the item

background_color

The background color to be displayed with the item

name

Name of the item

external_link

External link to the original website for the item

asset_contract

Dictionary of data on the contract itself (see asset contract section)

owner

Dictionary of data on the owner (see account section)

traits

A list of traits associated with the item (see traits section)

last_sale

When this item was last sold (null if there was no last sale)

Traits

Traits are special properties on the item, that can either be numbers or strings. Below is an example of how OpenSea displays the traits for a specific item.

Here are some of the fields contained in a trait:

trait_type

The name of the trait (for example color)

value

The value of this trait (can be a string or number)

display_type

How this trait will be displayed (options are number, boost_percentage, boost_number). See the adding metadata section for more details

Asset contracts

Asset contracts contain data about the contract itself, such as the CryptoKitties contract or the CryptoFighters contract. Here are the field associated with an asset contract:

address

Address of the asset contract

name

Name of the asset contract

symbol

Symbol, such as CKITTY

image_url

Image associated with the asset contract

description

Description of the asset contract

external_link

Link to the original website for this contract

Event Object

Asset events represent state changes that occur for assets. This includes putting them on sale, bidding on them, selling, them, cancelling sales, composing assets, transferring them, and more.

Suggest Edits

Account Object

Accounts represent wallet addresses and associated usernames, if the owner entered one on OpenSea. Here's an overview of the fields contained in an account:

Field name

Description

address

The Ethereum wallet address that uniquely identifies this account.

profile_img_url

An auto-generated profile picture to use for this wallet address. To get the user's Ethmoji avatar, use the Ethmoji SDK.

user

An object containing username, a string for the the OpenSea username associated with the account. Will be null if the account owner has not yet set a username on OpenSea.

config

A string representing public configuration options on the user's account, including affiliate and affiliate_requested for OpenSea affiliates and users waiting to be accepted as affiliates.

Query Params

owner

string

The address of the owner of the assets

token_ids

array of strings

An array of token IDs to search for (e.g. ?token_ids=1&token_ids=209). Will return a list of assets with token_id matching any of the IDs in this array.

asset_contract_address

string

The NFT contract address for the assets

asset_contract_addresses

array of strings

An array of contract addresses to search for (e.g. ?asset_contract_addresses=0x1...&asset_contract_addresses=0x2...). Will return a list of assets with contracts matching any of the addresses in this array. If "token_ids" is also specified, then it will only return assets that match each (address, token_id) pairing, respecting order.

search

string

Keyword search. Does a case-insensitive search on asset names

order_by

string

How to order the assets returned. If the ordering option isn't implied by last_sale or num_sales, the API will return its value in an attribute with the same name. By default, the API returns the fastest ordering (contract address and token id). Options you can set are token_id, listing_date (the last off-chain sell order's creation date), current_price (the lowest off-chain sell order's current price), current_escrow_price (the lowest price for an escrowed asset on sale), top_bid (the highest off-chain buy order's W-ETH amount), sale_date (the last sale's transaction's timestamp), sale_count (number of sales), visitor_count (number of unique visitors), and sale_price (the last sale's total_price)

order_direction

string

Can be asc for ascending or desc for descending

trait__{value_type}__{trait_type}

string

Search for assets with specific traits, e.g. trait__int__generation=0 to search for Gen 0 assets. value_type can be either int, float, or string and represents the data type of the value. trait_name is dependent on the type of asset being searched, but options will appear in the results and also in each category's sidebar on opensea.io/assets

on_sale

boolean

Set on_sale to true to retrieve only assets for sale, i.e. ones with an open sell order, bundle for sale, or escrow auction. Set to false to show assets with no known sell order or escrow auction

offset

string

Offset

limit

string

Limit. Defaults to 20, capped at 300.

collection

string

Limit responses to members of a collection. Case sensitive and must match the collection slug exactly. Will return all assets from all contracts in a collection. For more information on collections, see our collections documentation.

Headers

X-API-KEY

string

Your optional API Key (contact us to request one!)

To retrieve assets from our API, call the /assets endpoint with the desired filter parameters.

Note: sorting by listing_date or current_price will filter out assets that are not on sale, along with assets being sold on an escrow contract (where the true owner doesn't own the asset anymore). To sort assets by their escrowed auction price, use current_escrow_price for your order_by parameter. You'll need to do this to display and sort auctions from the CryptoKitties contract, for example.

Auctions created on OpenSea don't use an escrow contract, which enables gas-free auctions and allows users to retain ownership of their items while they're on sale. So this is just a heads up in case you notice some assets from opensea.io not appearing in the API.

The endpoint will return the following fields:

assets

List of Asset Object

The /collections endpoint provides a list of all the collections supported and vetted by OpenSea. To include all collections relevant to a user (including non-whitelisted ones), set the owner param.

Each collection in the returned area has an attribute called primary_asset_contracts with info about the smart contracts belonging to that collection. For example, ERC-1155 contracts maybe have multiple collections all referencing the same contract, but many ERC-721 contracts may all belong to the same collection (dapp).

You can also use this endpoint to find which dapps an account uses, and how many items they own in each - all in one API call!

Getting Started with the Orderbook

This page will help you get started with OpenSea Orderbook.

You can use this endpoint to query the OpenSea orderbook for buy orders (bids and offers) and sell orders (auctions, listings, and bundles). If you're using JavaScript, you can also use the SDK (https://github.com/ProjectOpenSea/opensea-js#fetching-orders), or fork the starter project, pictured below.

The orderbook follows the Wyvern Protocol schema. Some of the terminology might be new to you. We'll do a brief overview here, but contact us via email or Discord if you'd like additional help.

This API is rate-limited. If you'd like to use it in a production environment, request an API key here.

Terminology

What are orderbooks and how do they work?

An orderbook is just a list of orders that an exchange uses to record the interest of buyers and sellers. On OpenSea, most actions are off-chain, meaning they generate orders that are stored in the orderbook and can be fulfilled by a matching order from another user.

Signatures vs Transactions

On Ethereum, whenever blockchain state is changed (e.g. when an asset moves from one account to another, or funds are traded between accounts), a transaction needs to occur. All transactions require Ether as payment, and in this form the payment is called gas. On many other marketplaces, users have to pay gas to list items for sale or to purchase them, but OpenSea is heavily optimized to prevent users from having to spend gas.

When a user lists an item for sale, they simply sign their intent to exchange the item for payment. This intent is stored in the OpenSea orderbook as a sell order, and does not create a transaction. When a buyer comes along and decides to accept the listing price, the buyer can sign a buy order as a counter-order to be matched with the sell order.

The buyer can pay the gas to create a transaction to match the two orders together, or the buyer can have OpenSea match it for them in the case of English Auctions. In that scenario, no user pays gas, and both orders are stored in the orderbook. In all other scenarios, only the first order (the "maker" order) is stored.

Makers and Takers

All orders have a maker address field and taker address field. A maker is the first mover in a trade. Makers either declare intent to sell an item, or they declare intent to buy by bidding on one. A taker is the counterparty who responds to a maker's order by, respectively, either buying the item or accepting a bid on it.

Another way of putting this is that the maker is the user that is "creating liquidity," and the taker is the user that comes along and clears it away. On OpenSea, orders can be public, where the taker is the null address (0x0000000000000000000000000000000000000000) and anyone can take the order, or private, where the taker is a specific user's account. Private orders can only be fulfilled by a specific account - no other account is allowed by the smart contract.

Bids vs Offers

Bids and offers are both buy orders. You can differentiate between bids and offers by examining the taker on the order object. Buy orders with the null address as their takers are offers. Buy orders with an address other than the null address as their takers are bids.

An offer is unsolicited. Any owner of an asset with an offer on it can accept the offer, even if the current owner was not the asset's owner at the time the offer was made.

A bid, in contrast, is made in response to the creation of an English auction. Bids are personal to the English auction's creator and are eligible to be automatically matched with the English auction's original sell order at the end of the English auction. The creator of an English auction may choose to accept a bid before the English auction ends. For more information on OpenSea's English auctions, see our article on the subject.

Timestamps

Orders have three time components on them: created_date, listing_time, and expiration_time. The created_date is the date the order was made. OpenSea.js, along with camel-casing these properties for JavaScript, will auto-convert created_date into a UTC timestamp called createdTime, which is the number of seconds since the UNIX epoch (similar to listingTime and expirationTime).

The listing_time is the timestamp that the order will start to be fulfillable. For most orders this is right when they're made, but for English Auctions it's when the user wants the auction to end (this is added security to make sure it's not matchable until then).

The expiration_time is the timestamp that the order will no longer be fulfillable ever. For most orders this is when the user wants them to expire, but for English Auctions it's set to a point later in the future, just so that OpenSea's servers have enough time to match them with the highest bid.

Retrieving orders

How to fetch orders from the OpenSea orderbook

gethttps://api.opensea.io/wyvern/v1/orders

curl --request GET \
  --url https://api.opensea.io/wyvern/v1/orders

var request = require("request");

var options = { method: 'GET',
  url: 'https://api.opensea.io/wyvern/v1/orders' };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

require 'uri'
require 'net/http'

url = URI("https://api.opensea.io/wyvern/v1/orders")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Get.new(url)

response = http.request(request)
puts response.read_body

var data = JSON.stringify(false);

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function () {
  if (this.readyState === this.DONE) {
    console.log(this.responseText);
  }
});

xhr.open("GET", "https://api.opensea.io/wyvern/v1/orders");

xhr.send(data);

import requests

url = "https://api.opensea.io/wyvern/v1/orders"

response = requests.request("GET", url)

print(response.text)

bundled

boolean

Only show orders for bundles of assets

include_invalid

boolean

Include orders marked invalid by the orderbook, typically due to makers not owning enough of the token/asset anymore

listed_after

date-time

Only show orders listed after this timestamp. Seconds since the Unix epoch.

listed_before

date-time

Only show orders listed before this timestamp. Seconds since the Unix epoch.

token_id

string

Filter by the token ID of the order's asset

token_ids

array of strings

Filter by a list of token IDs for the order's asset

side

int32

Filter by the side of the order. 0 for buy orders and 1 for sell orders.

sale_kind

int32

Filter by the kind of sell order. 0 for fixed-price sales or min-bid auctions, and 1 for declining-price Dutch Auctions. NOTE: use only_english=true for filtering for only English Auctions

limit

int32

Number of orders to return (capped at 100).

offset

int32

Number of orders to offset by (for pagination)

order_by

string

How to sort the orders. Can be created_date for when they were made, or eth_price to see the lowest-priced orders first (converted to their ETH values)

order_direction

string

Can be asc or desc for ascending or descending sort. For example, to see the cheapest orders, do order_direction asc and order_by eth_price.

Rinkeby API Overview

The Rinkeby API is used for browsing non-fungible assets on the Ethereum Rinkeby test network. Creating and purchasing assets on this network requires Rinkeby ether, which is free. To acquire some, visit https://faucet.rinkeby.io/ and authenticate using your Twitter account.

The API is identical to the OpenSea mainnet API, except the base URL is https://rinkeby-api.opensea.io/api/v1/.

This API is rate-limited. If you'd like to use it in a production environment, request an API key here.
