Mail a physical card

Use t2 services. Write a warm note for {recipient}, render it as a card front via fal.ai, and mail it to {address} via Lob.

import { T2000 } from '@t2000/sdk';

const agent = await T2000.create();

const occasion = 'birthday';

// Lob needs a STRUCTURED address (line1 / city / state / zip / country),
// not one crammed string — a single `address_line1` fails validation.
const recipient = {
  name: 'Mum',
  address_line1: '210 King St',
  address_city: 'San Francisco',
  address_state: 'CA',
  address_zip: '94107',
  address_country: 'US',
};

const note = await agent.pay({
  url: 'https://mpp.t2000.ai/anthropic/v1/messages',
  method: 'POST',
  headers: { 'anthropic-version': '2023-06-01' },

    messages: [{
      role: 'user',
      content: `Write a warm ${occasion} note from me to ${recipient.name}. 3-4 sentences. Personal, not gushing.`,
    }],
  }),
