# Single\-to\-Double Stroller 3\.0 \| live price, prepared checkout ## Built for shopping agents: what RoboTrunk does for every product We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built. RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product. - **Deep research:** We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. `check_product` returns them with a source for each. *This product:* 66 checked facts, research depth trimmed read, checked 2026-10-12T15:09:18.883Z, in the [evidence pack](/agent/evidence/hellomockingbird-com--mockingbird-double-stroller). - **Receipts:** Every published fact has a receipt showing its source quote. `check_product` and `get_product` return the checked facts that have one. *This product:* each checked fact listed below has one; the source quotes are in the [evidence pack](/agent/evidence/hellomockingbird-com--mockingbird-double-stroller). - **Safety:** `check_product` asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. *This product:* this page holds no recall result for it yet; `check_product` asks the regulators now. - **Recall watch:** `watch_recalls` tells the buyer if a product bought here is recalled later. - **Second-hand listings:** `check_listing` runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. - **The real price:** The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on: `check_product` and `search_catalog` take the buyer's country and postcode. *This product:* this store's price was read from its catalogue at 2026-10-18T19:33:40.395Z. - **A checkout that finishes:** RoboTrunk lists only stores whose agent checkout it has verified. `create_checkout` prepares the order at the store; `complete_checkout` returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs. - **Markdown copy:** Every page has a Markdown copy: [this page's copy](https://robotrunk.com/products/ucp/hellomockingbird-com/15221782282406.md). - **Photos and ratings:** Search results carry the product photo and, where the store's own page publishes one, its rating (`search_catalog`). - **Fit answers:** `check_fit` answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known. - **Back-in-stock watches:** `watch_back_in_stock` starts a watch on a listing the store shows as sold out; `get_back_in_stock_watch` shows when it is back in stock. - **Maker's manual:** `ask_product_manual` answers from the maker's manual with the exact passage and page, or says the manual does not cover it. - **Tools and guide:** Every tool and its description is at https://robotrunk.com/mcp; the guide is at [/agents\.md](/agents.md). - **Research from other stores:** Coming soon: reading other stores' listings of the same product as research sources. Sold and shipped by hellomockingbird\.com, hellomockingbird.com; payment happens on the store's own checkout.

Each carries that source's link and the time RoboTrunk read it. 66 checked facts, checked 2026-10-12T15:09:18.883Z. Research depth: trimmed read. Deep read: the store's own data and 11 outside pages \(the store's own product page; maker page; manual; blog; review; regulator recall search \(CPSC \(United States\)\); regulator recall search \(Health Canada\); video review \(derived summary of its captions\)\), each read in full by RoboTrunk and trimmed to its main content, then written up and checked\. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read\. Recall status was checked directly with CPSC \(United States\), Health Canada: A CPSC recall search for Mockingbird returned one record, but that record's recall fields were null and the search reported a provider error, so it gives no recall notice for this model\. A Health Canada open\-data search found no records mentioning Mockingbird\. A 2022 voluntary recall of the original Mockingbird single and single\-to\-double stroller over hairline frame cracks is described on a blog review, not in a regulator notice, and concerns earlier models rather than the 3\.0\.
