## Connecting to the Chain (API's)

{% hint style="info" %}
All Phantasma Phoenix RPCs come with both REST and RPC interfaces. Everywhere in documentation RPC nodes will be just called RPCs despite the fact that they support both protocols.
{% endhint %}

To access REST documentation served through Swagger, just open RPC's URL in interner browser. It will automatically redirect you to documetation page. For example, if you'll open <https://testnet.phantasma.info/> URL, you will be redirected to this Swagger page: <https://testnet.phantasma.info/swagger/index.html>

To send query through RPC protocol, you need to add '/rpc' to URL, for example for testnet this is the full address of RPC: <https://testnet.phantasma.info/rpc>

REST and RPC interfaces use same names for endpoints and arguments. This way REST API Documentation can be easily used to compose RPC queries.
