Get an Anthropic (Claude) API Key

For: Tenants who want to use their own AI key (cost goes directly to your account). Time: 5 minutes.

Why bring your own key?

• Transparent cost: the LLM bill goes straight to your Anthropic account, visible on Anthropic’s dashboard.
• Full control: you set the spending limit, monitor per model, and disable any time.
• Compliance: regulated industries (finance, healthcare) often require own-key for auditable data flow.

If you do not want to manage this, leave the field empty. Danum provides a fallback and bills the usage in your monthly invoice (see Usage & Billing).

Steps

1. Create an Anthropic account

• Go to https://console.anthropic.com/
• Click Sign Up (top right). You can use Google OAuth or email.
• Verify your email (check inbox).

2. Set up billing

• After signing in, open Billing in the sidebar.
• Click Add payment method and enter your card (Mastercard or Visa).
• Add initial credit (minimum $5, about Rp 78,000). Credits are consumed per API call.
• Set spending limit: set “Monthly usage limit” to a comfortable number (for example $50, about Rp 780,000). When the limit is hit, the API stops. This prevents over-charge.

3. Generate the API key

• Open API Keys in the sidebar.
• Click Create Key.
• Name the key (for example danum-ai-production).
• Copy the key now. Anthropic only shows it once. If you lose it, create a new one.
• Format: starts with sk-ant- and is about 100 characters long.

4. Enter it in the Danum dashboard

• Open https://ai.numintek.com/app/settings/llm-keys
• Find Anthropic API Key.
• Paste the key and click Save.
• Danum encrypts it (AES-256-GCM per tenant) and starts using it for all your AI requests within 60 seconds.

Verify

• Send a message to your channel (WhatsApp / Widget / Telegram) and wait for the AI reply.
• Check the Anthropic dashboard > Usage — you should see new usage.
• Check the Danum dashboard > Usage & Billing — token counts go up, but AI cost is 0 (because you use your own key; Danum does not charge you).

Cost estimate

Default Danum model is Claude Sonnet 4.6:

• Input: $3 per 1M tokens (about Rp 46,500)
• Output: $15 per 1M tokens (about Rp 232,500)

For a small hospitality tenant (500 chats per month, roughly 10-turn conversations) expect Rp 50,000-200,000 per month.

Troubleshooting

Q: I got an invalid_api_key error. Check the key format (sk-ant-*). If you just created it, wait 10 seconds and retry.

Q: I got an insufficient_credit error. Top up credit at Anthropic dashboard > Billing.

Q: Can I use a different model? Yes, but the per-tenant model selection UI is not built yet. Contact support if you need it.

Q: Is the key safe on Danum? Yes. AES-256-GCM encryption with per-tenant HKDF-SHA256 key derivation. Ciphertext lives in the Danum DB; the decryption key is never logged or backed up alongside the ciphertext.
