Shop.app API endpoint
Use Crawlora's List Shop.app product variants API to extract supported public Shop.app data as structured JSON. This page includes request parameters, cURL examples, response schema, error behavior, credit cost, and a Playground link for testing before integration.
/shop-app/products/{id}/variantsReturns adjacent variants for a Shop.app product. selected_options must be a JSON object when provided. Repeated option filters may also be sent as option.Name=value or option[Name]=value. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.
Request parameters are generated from the active endpoint catalog. Required values must be sent before Crawlora can call the upstream public web data source.

This endpoint is executed through Crawlora's managed scraping infrastructure.
- Invalid `selected_options` JSON returns an invalid-param error before upstream IO. - Blocked pages, malformed route data, and empty parsed variants return an upstream error. Example response: ```json { "code": 200, "msg": "OK", "data": { "product_id": "4596217053229", "variants": [ {"id": "34761278160941", "title": "Black / 7 / 6E", "available_for_sale": true} ] } } ```
Crawlora does not silently return bad data when the upstream page cannot be used.
| Status | Common failure case |
|---|---|
| 400 | Invalid input or missing required parameter |
| 429 | Plan or endpoint rate limit exceeded |
| 500 | Internal execution error |
| 502 | Upstream platform failed, returned unusable HTML, or served a challenge page that could not be resolved |
When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
