Configure

  });

  let input = '';

  async function send() {
    if (!input.trim()) return;
    const userMsg = { role: 'user' as const, content: input };
    input = '';
    await chat.sendMessage([...$chat.messages, userMsg]);
  }
</script>

{#each $chat.messages as msg}
  <div class="message {msg.role}">
    <strong>{msg.role}:</strong> {msg.content}
  </div>
{/each}

{#if $chat.isLoading}
  <p>Thinking...</p>
{/if}

{#if $chat.error}
  <p class="error">Error: {$chat.error.message}</p>

<button on:click={send} disabled={$chat.isLoading}>Send</button>

SvelteKit — Server Route

For server-side calls, use the raw API directly (no browser auth exposure):

// src/routes/api/chat/+server.ts
import { AINATIVE_API_KEY } from '$env/static/private';
import type { RequestHandler } from './$types';

export const POST: RequestHandler = async ({ request }) => {
  const { messages } = await request.json();

  const resp = await fetch('https://api.ainative.studio/v1/public/chat/completions', {
    method: 'POST',
    headers: {
      'X-API-Key': AINATIVE_API_KEY,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'claude-3-5-sonnet-20241022',
      messages,
    }),
  });

  return new Response(resp.body, {
    headers: { 'Content-Type': 'application/json' },
  });
};

Environment Variables

# .env
VITE_AINATIVE_API_KEY=ak_your_key         # Client-safe (public key only)
AINATIVE_API_KEY=ak_your_key              # Server-side (SvelteKit $env/static/private)

Use server routes for production — never expose API keys in client bundles.
