Splitwise CLI Setup

Splitwise can be configured headlessly with `kosmokrator integrations:configure splitwise`.

# Install KosmoKrator first if it is not available on PATH.
curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

# Configure and verify this integration.
kosmokrator integrations:configure splitwise --set access_token="$SPLITWISE_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmokrator integrations:doctor splitwise --json
kosmokrator integrations:status --json

Credentials

Authentication type: Bearer token bearer_token. Configure credentials once, then use the same stored profile from scripts, coding CLIs, Lua code mode, and the MCP gateway.

Call Splitwise Headlessly

Use the generic call form when another coding CLI or script needs a stable universal interface.

kosmo integrations:call splitwise.splitwise_list_expenses '{
  "group_id": 1,
  "friend_id": 1,
  "dated_after": "example_dated_after",
  "dated_before": "example_dated_before",
  "limit": 1,
  "offset": 1
}' --json

Use the provider shortcut form for shorter human-facing commands.

kosmo integrations:splitwise splitwise_list_expenses '{
  "group_id": 1,
  "friend_id": 1,
  "dated_after": "example_dated_after",
  "dated_before": "example_dated_before",
  "limit": 1,
  "offset": 1
}' --json

Agent Discovery Commands

These commands return structured output for coding agents that need to inspect capabilities before choosing a function. 

kosmo integrations:docs splitwise --json
kosmo integrations:docs splitwise.splitwise_list_expenses --json
kosmo integrations:schema splitwise.splitwise_list_expenses --json
kosmo integrations:search "Splitwise" --json
kosmo integrations:list --json

All CLI Functions

Every function below can be called headlessly. The generic form is stable across all integrations; the provider shortcut is shorter but specific to Splitwise.
