Host gate.computer 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 https://gate.computer/hello.wasm $ curl -X PUT -H "Content-Type: application/wasm" --data-binary @hello.wasm "https://gate.computer/gate-0/module/sha256/3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3?action=call&function=greet" 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 "https://gate.computer/gate-0/module/ipfs/QmQV5N5LQnPV2M8TLXcfYUfW1EKiTkcZejvY3zPFMc5qhg?action=call&function=greet" hello, world

Anonymous usage with browser

Execute by IPFS hash via browser:

https://gate.computer/ipfs/QmQV5N5LQnPV2M8TLXcfYUfW1EKiTkcZejvY3zPFMc5qhg?function=twice

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 gate.computer/cmd/gate@latest

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

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

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

Discover the service catalog:

$ gate gate.computer call -s listener /ipfs/QmfE6F5AjsgywoWVQeypuGc9PcgQ2Ch6s6Bg7MHWNVKTdC { "services": [ { "name": "catalog", "revision": "0" }, { "name": "gate.computer/localhost", "revision": "0" }, { "name": "gateservice.net/listener", "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.

An entry function name wasn't specified for the catalog program because it has implicit main function.
