## Tools (as reported by the server, not verified)

- `connect\_account`: Get a Premier Letters API key without the user copying one by hand. Pass the user's email and your name; we email them a link to approve \(they can sign up from it if they have no account\). Then call check\_connection with the returned request\_id and poll\_secret every 10-30 seconds until it returns th
- `check\_connection`: Check whether the user approved a connect\_account request. Returns status pending, denied, expired or claimed, or, exactly once, status approved with the api\_key. Poll every 10-30 seconds.
- `get\_pricing`: Get a live price quote for a Premier Letters order. Pass char\_count \(or letter\_count for a rough estimate\) plus optional mailing\_option and paper\_type to get a per-piece and total price, in cents. No account needed. Orders under 5 pieces carry a $0.99 per-piece handling fee \(included in total\_cents\)
- `list\_handwriting\_styles`: List available handwriting styles \(fonts\) for a letter order. Use the returned "id" as options.handwriting\_style / handwriting\_style when creating an order or previewing.
- `list\_templates`: List the authenticated user's saved letter templates.
- `verify\_address`: Verify and standardize a US mailing address via USPS. Use before create\_order to catch typos and get the USPS-standardized form.
- `preview\_letter`: Render a preview of a handwritten letter \(as an SVG image\) and get its price, before creating an order. Does not save anything.
- `create\_order`: Create and pay for a Premier Letters order — a real, handwritten letter mailed via USPS. Requires a Premier Letters API key. Use get\_pricing or preview\_letter first to confirm the price. For payment, "card\_on\_file" charges the caller's saved card immediately, "balance" pays from the prepaid account
- `get\_order\_status`: Get an order's status, delivery/tracking summary, and per-recipient mail status.
- `list\_orders`: List the authenticated user's recent orders.
- `get\_balance`: Get the authenticated account's prepaid balance \(balance\_cents\) and the top-up rules: minimum and maximum top-up, bonus tiers and suggested amounts. Orders paid with payment.method "balance" skip the small-order handling fee. Use create\_topup\_link to add funds.
- `create\_topup\_link`: Create a Stripe Checkout link that adds prepaid credit \(plus any bonus tier\) to the authenticated account. Give checkout\_url to the human to pay in a browser; the balance updates once they pay \(check with get\_balance\). amount\_cents must be a whole number between min\_cents and max\_cents from get\_bala
