Use GST Cranes for

  • Used mobile and crawler cranes for sale.
  • Public Crane Wiki company and fleet records.
  • Buyer wanted ads, which are requests to buy and not for-sale inventory.
  • Safe handoff to the website when an authenticated user action is required.

Quickstart

Public read access does not require OAuth or API keys. Account actions, credits, listing creation, wanted-ad publishing, saved alerts, and promotion purchases require the normal GST Cranes browser sign-in flow.

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.

Read-only sandbox first API call

Use /sandbox for the crawlable sandbox surface and /api/sandbox/first-call for the first public agent API call. It needs no API key, reads no account data, spends no credits, and has no side effects.

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.
