An invite-only private household purchase ledger with HTTP APIs for agents.

- Public integration guide: /developers
- Public machine-readable API guide: /developers/agent.json
- Current data practices: /privacy
- Owner-only connection management (sign-in required): /connections
- Authenticated, client-specific capabilities: /api/agent/capabilities

To report a bug, missing field/endpoint or integration blocker, use a separate
operator-issued feedback:create key with POST /api/agent/feedback (see /developers).
Never include receipts, household members, addresses, purchase details or secrets.

Ask an invited ledger owner for an explicitly scoped bearer key. Never ask for a
Google password or browser cookie. Never place the key in URLs or client-side code.
The public guide describes possible capabilities; it does not grant data access.
This service does not implement MCP or A2A. Purchases do not prove current pantry
availability. Prices are historical. Only perform writes requested by the user.
