Getting Started
Email api@silvergoldbull.com with your existing customer ID in order to get an API key. Your API key will have access to the same store as your account. To enable the API in multiple countries and languages you can create an account in each store and then generate keys. Advanced services like white labelling and wholesale pricing require volume commitments, please contact us.
This is a JSON REST API. It makes full use of response codes.
It is recommended to use a content type header of text/json when posting a JSON body.
created_at fields are always UTC.
Just like on our website, orders are binding once placed and guaranteed by your own account. You are making a promise to pay and honor your order commitment. We immediately hedge your order and will lock your order price no matter what happens.
Authentication
Authentication and identification to the Silver Gold Bull API is done by providing an API key in the X-API-KEY header on every request.
The API requires that all communication is secured using HTTPS/TLS.
All keys are live. Declarations can be made if you want to test order placement.
Remember to treat your API Keys as passwords and keep them secret. They should not be included in public repositories, client side code, etc.
Rate Limiting
60 requests may be made per 60 second period.
Errors
In the event of a client or server error, the response will contain the standard 4xx or 5xx respectively, accompanied by a well-formed JSON body describing the issue, e.g., a required field was omitted.

Quote Order
POST /orders/quote
Obtain a live market quote for a new order. If the response is 200 OK then it is valid and the same data can likely be submitted as an order. To guarantee your order being at or below your price, use bid_price. If using bid_price then understand that a successful quote one moment may not submit as an order the next due to market price movements. With or without bid_price you will always get our best price.
