Prices are quoted in INR and ship to IN. Content locales: en-IN, hi-IN.
Prices, stock and delivery estimates must always be read live from the commerce endpoints below — never from cached pages.

## Acting on behalf of a buyer

- Anonymous agents may read the catalogue, offers and policies, and may create checkout sessions that the buyer completes themselves at `handoffUrl`.
- To act with a buyer's permission, send them to https://web.sathishai.online/account/agents/authorize?agent={agentId}&scopes={comma-separated scopes}. The buyer signs in, reviews the scopes (`catalog:read`, `offers:read`, `cart:write`, `checkout:write`, `orders:read`, `support:write`, `purchase:execute`) and may grant a spending mandate.
- Authenticate with the issued agent key: `Authorization: Bearer ecom_agent_…`. Completing a purchase additionally requires the `purchase:execute` scope and a `purchaseAuthorizationId` (mandate) that covers the order total.
- Every agent-initiated cart, checkout and order is attributed to the agent identity; send `X-Agent-Intent: <short description>` with checkout sessions so the merchant can see why.
- Respect `Cache-Control` and `X-RateLimit-*` headers. Do not scrape HTML for prices; use the endpoints above.
