Host should be an operational Gate.
It can run your code.

Live demo

Running greet function of webassembly module /ipfs/QmQV5N5LQnPV2M8TLXcfYUfW1EKiTkcZejvY3zPFMc5qhg.

The server call is made anonymously.

Anonymous usage with curl

Upload and execute:

$ curl -o hello.wasm $ curl -X PUT -H "Content-Type: application/wasm" --data-binary @hello.wasm "" hello, world

SHA-256 hash of the uploaded module contents must be included in the URL.

Executing the same module via IPFS:

$ curl -X POST "" hello, world

Anonymous usage with browser

Execute by IPFS hash via browser:

Command line client with authentication support

Prebuilt binaries are available for Linux x86-64/ARM64, macOS x86-64/ARM64, and Windows x86-64/ARM64.

Alternatively, it can be built using Go:

$ go install

If necessary, create an Ed25519 private key using OpenSSH authentication key utility:

$ ssh-keygen -t ed25519 # Defaults to ~/.ssh/id_ed25519. $ ssh-keygen -t ed25519 -f filename # If you want to use a Gate-specific key (see below).

Manage resources bound to your public key:

$ gate launch ./hello.wasm greet 01234567-89ab-odef-0123-456789abcdef $ gate io 01234567-89ab-cdef-0123-456789abcdef hello, world $ gate instances 01234567-89ab-odef-0123-456789abcdef HALTED with result 0 $ gate modules 3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3

The private key location can be overridden on the command line or in a configuration file:

$ gate -o identityfile=filename call 3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3 greet hello, world $ mkdir -p ~/.config/gate $ echo 'identityfile = "filename"' >> ~/.config/gate/client.toml

Discover the service catalog:

$ gate call -s listener /ipfs/QmfE6F5AjsgywoWVQeypuGc9PcgQ2Ch6s6Bg7MHWNVKTdC { "services": [ { "name": "catalog", "revision": "0" }, { "name": "", "revision": "0" }, { "name": "", "revision": "0" }, { "name": "identity", "revision": "0" }, { "name": "origin", "revision": "0" }, { "name": "random", "revision": "0" }, { "name": "scope", "revision": "0" } ] }

Service availability may vary based on authorization and scope. Discover the services currently available for anonymous use.
