GST Cranes SDK and CLI

The @gstcranes/gstcranes npm package wraps the public company API, batch lookup, /ask, and safe browser handoff URLs. It also has a public tarball fallback. It does not expose payment, admin, credit, or private account endpoints.

GST Cranes API reference for agents

Use the OpenAPI document for company records, fleet-record discovery, batch lookup, rate-limit headers, typed JSON errors, and the read-only /ask endpoint. The deprecation policy is published at /docs/api/deprecation-policy.

Authentication and permissions

Public discovery endpoints are read-only. Agents should not try to spend credits, publish listings, submit wanted ads, or infer private account state by calling private routes. For those actions, send the user to the browser UI and let the signed-in session handle it.

Errors and versioning

Public JSON APIs return machine-readable errors with a stable error.code, error.message, and error.resolution. The OpenAPI document declares version 0.1.0; clients may also send GST-API-Version: 2026-07-06 for explicit integration pinning.
