Create an API Key

An API key is required to use Lighthouse, it can be generated using Files Dapp UI (check quick start for more detail), CLI, and SDK. Refer to the given code examples to generate an API key based on your preferred environment.
In general, to create an API key there are two steps involved: 1. The user requests an authentication message from the message API. 2. The user signs the auth message to get the API key.
JS SDK
API
CLI
import axios from 'axios'
import { ethers } from 'ethers'
import lighthouse from '@lighthouse-web3/sdk'
const signAuthMessage = async(privateKey, verificationMessage) =>{
const signer = new ethers.Wallet(privateKey)
const signedMessage = await signer.signMessage(verificationMessage)
return(signedMessage)
}
const getApiKey = async() =>{
const wallet = {
publicKey: 'YOUR_PUBLIC_KEY', // Ex: '0xEaF4E24ffC1A2f53c07839a74966A6611b8Cb8A1'
privateKey: 'WALLET_PRIVATE_KEY'
}
const verificationMessage = (
await axios.get(
`https://api.lighthouse.storage/api/auth/get_message?publicKey=${wallet.publicKey}`
)
).data
const signedMessage = await signAuthMessage(wallet.privateKey, verificationMessage)
const response = await lighthouse.getApiKey(wallet.publicKey, signedMessage)
console.log(response)
}
getApiKey()
First, we need to get an authentication message that should be signed in order to generate an API key
curl https://api.lighthouse.storage/api/auth/get_message?publicKey=<publicKey>
This will send a message(string) in response that has to be signed by the user, the signature will be required to generate the API key
curl -X POST -d '{"publicKey": "value1", "signedMessage": "value2", "keyName": "value3"}' https://api.lighthouse.storage/api/auth/get_api_key
Before generating the API key using CLI make sure there is a wallet created or an existing wallet is imported in CLI. To check your wallet use the following command
lighthouse-web3 wallet
#Returns
#Public Key: 0x92a605b54a7F3171aF7D093d8CeD874236ea96A5
#Network: polygon
If there is no wallet, create one or import one using
lighthouse-web3 create-wallet
lighthouse-web3 import-wallet --key <private_key>
Now run the following command to create API key
lighthouse-web3 api-key --new
