## APIs and packages

- [OpenAPI description](https://archstone.dev/openapi.yaml): machine-readable contract for the console's two public operations above (the demo capability below has its own contract, described separately)
- [For developers](https://archstone.dev/developers): the technical side — the connector URL, Claude Code one-liner and curl for the demo, the CDL capability declaration, how the compiler and verify work, neutral hosting, and what is open source
- [Demo capability: tourism.search](https://archstone.dev/developers#try-it): public remote MCP server at https://demo.archstone.dev/mcp and JSON endpoint POST https://demo.archstone.dev/v1/search; synthetic data, no key
- [Verify my API](https://archstone.dev/verify): paste your own OpenAPI document's address and get a free, read-only report of what an agent gateway would call and what it would leave alone; nothing stored beyond the access log, no account
- [@archstone/collector](https://www.npmjs.com/package/@archstone/collector): console collector (SDK); outbound-only audit sink and scheduled verify probe
- [Pilot console](https://console.archstone.dev/sign-up): hosted Archstone console, free during the pilot; import an OpenAPI description, publish capabilities as MCP endpoints, and keep drift history and audit records
