...To interact with the API, you need to have a local daemon running. It needs to be open on the right port. 5001 is the default and is used in the examples below, but it can be set to whatever you need. In a web browser IPFS HTTP client (either browserified or CDN-based) might encounter an error saying that the origin is not allowed. This would be a CORS ("Cross Origin Resource Sharing") failure: IPFS servers are designed to reject requests from unknown domains by default. You can whitelist the domain that you are calling from by changing your ipfs config.
