Make and look after API keys

Open Developer platform, then Keys, and press New key. Copy it straight away. We only show the full key once and keep a hash, so we cannot show it to you again.

Good habits:

• Make one key per app or server, so you can switch one off without breaking the others.
• Limit a key to the addresses it is used from and the abilities it needs.
• If a key leaks, revoke it at once and make a new one. Revoking takes effect in seconds.

The developer documentation has the full API reference.
