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 we do not keep a copy, so save it somewhere safe.
Your API key
Copy it now. This is the only time it is displayed, and we do not store it.
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.
