CartrouteCan I read any Cartroute page as JSON?
Every public page on cart-route.com (products, categories, retailers, coupons, guides, pricing, status and these docs) returns structured JSON when requested with Accept: application/json or ?format=json. Page views are free, need no key, and are the cheapest way for a browsing agent to read the catalog.
How do I request JSON?
curl -H "Accept: application/json" https://cart-route.com/p/sony-wh-1000xm6 curl "https://cart-route.com/c/tvs?format=json" curl "https://cart-route.com/docs/errors?format=json"
HTML pages also advertise their JSON form with Link: <…?format=json>; rel="alternate"; type="application/json", and every response carries Link headers pointing to the OpenAPI description and the MCP server card.
Which pages have a JSON form?
| Page | JSON object |
|---|---|
/p/{slug} | product with offers, specs and 90-day price_history |
/c/{category} | category with every product in it |
/retailers, /retailers/{slug} | retailer_list, retailer |
/coupons | coupon_list |
/search?q= | search_result (anonymous preview: 5 a day) |
/guides, /guides/{slug} | guide_list, guide with live figures |
/docs/… | doc with the page text |
/pricing, /about, /status, / | pricing, about, status, page |
When should an agent use the API instead?
When it needs filters, sorting, pagination, idempotent retries or more than five searches a day. Page JSON is for reading known URLs, for example a product link a user pasted.
