Metadata

The Sequence Metadata API service offers a simple and fast API to query token & NFT metadata for Ethereum-compatible chains which is available as an submodule through the @0xsequence/metadata package or via HTTP requests. To learn how to use the Sequence Metadata service, please read:

Web / node.js Installation

Terminal

npm install 0xsequence

Terminal

npm install @0xsequence/metadata

This installation requires an API Access Key from Sequence Builder.

then in your app (using your API Access Key),

import { SequenceMetadata } from '@0xsequence/metadata'

const metadata = new SequenceMetadata('https://metadata.sequence.app', 'AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY')

NOTE: if you’re using @0xsequence/metadata from node.js, we recommend using node v18.x or newer.

Go Installation

go get -u github.com/0xsequence/go-sequence@latest

import (
	"github.com/0xsequence/go-sequence/metadata"
)

seqMetadata := metadata.NewMetadata("AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY")

contractInfo, err := seqMetadata.GetContractInfo(context.Background(), "polygon", "0x631998e91476DA5B870D741192fc5Cbc55F5a52E")
