How to get your Claude (Anthropic) API key
The Claude API is provided by Anthropic. Itinr uses it to extract events from your travel documents.
Pricing (as of 2026)
Anthropic gives $5 free credit to new accounts — enough for hundreds of itinerary extractions.
After that, you pay per token (very small per request).

For Itinr, Haiku 4.5 is plenty — one PDF extraction costs roughly $0.001.
Steps
- Go to https://console.anthropic.com and sign up (or log in).
- Verify your phone number — required for API access.
- Click your profile (top-right) → API Keys.
- Click Create Key.
- Give it a name (e.g.
Itinr) and choose permissions (default is fine).
- Copy the key immediately — it starts with
sk-ant-... and is only shown once.
- In Itinr → Settings → AI Models → Claude → paste the key into the API Key field.
- Tap Test Connection to verify.
Notes
- Region: Anthropic does not officially support Hong Kong. If you’re in HK without a VPN, the API may be blocked. Use the Free Default Model option instead.
- You can add billing limits in the Anthropic console to cap your monthly spend.
- Your key is stored only on your device (in iOS Keychain).
