Ordinals API Keys

Rate Limiting

  • This public API is free to use, and the default limit is 30 QPM. The unauthorized requests share the same "demo" key of the 30 QPM, so it's possible that you will see some 429 status code when trying it.
  • If you need a higher limit, please fill out this form to get an API key.
  • If calling the endpoints in batch, please add a small timeout between requests to avoid connection refusal (this applies to both users with and without API keys).
  • Feel free to join us on Discord!

Authorization Header

To access the instruction endpoints, you need to include an Authorization header in your HTTP requests. The value of the Authorization header should be Bearer followed by the API key.


Authorization: Bearer YOUR_API_KEY

Replace YOUR_API_KEY with the actual API key provided to you.
