If you're a developer and need to use AAPI in your project, all supported methods are available for import via the generated OpenAPI-compliant swagger.json.
To start querying, register an account at Ankr AAPI to get a unique API key. Then include it in the swagger.json above like this:
"servers":[{"url":"https://rpc.ankr.com/multichain/{YOUR_API_KEY}"}]
