Get a free API key
A key raises your quota from 2,000 to 10,000 calls per day. No account, no email, nothing to remember later. The key is shown once and never kept on our side, so save it somewhere safe.
Your API key
Copy it now. This is the only time it is displayed, and it is not stored anywhere on our side.
Use it as a bearer token: Authorization: Bearer YOUR_KEY. Keys expire after one year. Read the docs for examples.
Lost your key? Just get a new one. Up to 5 keys per day per network address.
