  magpie provider <id>                    show one provider and its models
  magpie provider add <preset> <key>      add a preset vendor   e.g. magpie provider add deepseek sk-…
                                          again, it adds another (deepseek-2); k=v pairs too: id, name, header.X-Foo
  magpie provider add <name> k=v…         add a custom vendor   k: url, anthropic, responses, key, models, catalog, icon, header.X-Foo, balance, balance.path, models.url
  magpie provider set <id> k=v…           change a provider's settings, with the same k=v pairs as add
  magpie provider key <id> <key>          change the API key
  magpie provider icon <id> <file|name>   give a custom provider a picture (PNG, JPEG, SVG…) or a built-in icon
  magpie provider fallback <id> <provider/model>…   where requests go when it's out of quota or down (none clears)
  magpie provider models <id> [ids…]      fetch the vendor's model list, or choose which models to expose
  magpie provider listed <id> yes|no      no: its models serve only through routing groups, not in the list
  magpie provider test <id>               send a tiny request through each endpoint
