What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of ottr.si controls every word below.

Search products

Find products by description and budget. Send plain text ("wireless headphones under £250") or data { "skill": "search_products", "query": "...", "max_price": 250 }. Returns offers with offer_id, price, delivery and whether OTTR can buy them. No key needed.

Compare two to five offers side by side. Data { "skill": "compare_products", "offer_ids": ["..."] }. No key needed.

Prepare a purchase for customer approval

Data { "skill": "purchase", "offer_id": "...", "quantity": 1 }. OTTR prepares the purchase and sends the customer a secure approval request. The task waits in auth-required until the customer approves, then works through funding and checkout to completed (with the order reference), or failed. Poll with GetTask. Requires an OTTR agent key and the customer's reference.

Prepare Purchase

Data { "skill": "prepare_purchase", "request_id": "REQ-1", "merchant": "example-retailer.com", "product": { "url": "https://...", "size": "UK 10", "quantity": 1 }, "purchase_constraints": { "maximum_total_amount": 150, "currency": "GBP" } } (same schema as POST /v1/commerce/purchases). Ottr verifies the product and prices the checkout. The task moves to auth-required with the customer approval link; after the customer approves on Ottr it works through payment and checkout to completed (with the verified order) or failed. Requires an OTTR agent key and the customer's reference.
