gstcranes 0.1.0

GST Cranes Python SDK for public read-only API discovery and webhook verification.

gstcranes

Official GST Cranes Python SDK for public read-only API discovery, Crane Wiki company records, OpenAPI metadata, and webhook signature verification.

The package only calls public read endpoints. Account actions such as listing creation, wanted-ad publishing, credits, promotions, saved alerts, and billing stay in the signed-in GST Cranes browser UI.

Install

pip install gstcranes

PyPI package: https://pypi.org/project/gstcranes/

Client

from gstcranes import GstCranesClient

client = GstCranesClient()
companies = client.list_companies(country="DE", limit=10)
company = client.get_company("bms-heavy-cranes")
answer = client.ask("companies with Liebherr LTM 1750 records")

Webhook verification

Use the raw request body exactly as received, the GST-Webhook-Timestamp header, the GST-Webhook-Signature header, and the endpoint secret shown once when you create a webhook endpoint.

from gstcranes import verify_webhook_signature

verify_webhook_signature(
    raw_body,
    timestamp=request.headers["GST-Webhook-Timestamp"],
    signature=request.headers["GST-Webhook-Signature"],
    secret=GST_WEBHOOK_SECRET,
)

The verifier raises WebhookSignatureError if the timestamp is stale or the HMAC-SHA256 signature does not match.
