**Dear all,**

As promised, you will find below the technical documentation on programmatic access to shprd trading signals. 👩‍💻👨‍💻

1\. Request a message to sign
-----------------------------

In a terminal shell (like Iterm) or on postman:

    curl --location --request POST 'https://0lii8gygqg.execute-api.eu-west-3.amazonaws.com/prod/auth/<the_address_holding_your_NPXs>/message' \
    --header 'Content-Type: application/json' \
    --data-raw '{
        "uri": "https://signals.shprd.finance",
        "version": "v0.1.180",
        "maxTs": "2023-07-06T12:21:22.123",
        "chainId": 1,
        "app": "signals.shprd.finance"
    }' 
    

*   Replace each <\*key\*> with appropriate value:
    
    *     
        
    
    *   Version: see latest version on cf.app.shprd.finance, at bottom-left of the screen
        
    *   ChainId integer can be either 1 (mainnet) or 56 (bsc)
        
*   This POST request will return:
    
        {
          message: string;
          id: string;
          error: string;
        }

    In a shell (like Iterm) or on postman:
    
        curl --location --request POST 'https://0lii8gygqg.execute-api.eu-west-3.amazonaws.com/prod/auth/<the_address_holding_your_NPXs>/verify' \
        --header 'Content-Type: application/json' \
        --data-raw '{
            "id": "<id>",
            "signature": "<signature>",
            "chainId": 1
        }'
        
    
    *   Replace each with appropriate value: **Prefix the signature value (“sig”) with “0x”** This POST request will return: { verified: boolean; jwt: string; chainId: number; balance (in NPXs): number; error: string; } 4.
