      <description>&lt;p&gt;Hey everyone,&lt;/p&gt;

&lt;p&gt;I'm currently working on a project and encountering some issues trying to query from block 1. I need an archive node, but the RPCs I've tried so far don't exactly works.&lt;/p&gt;

&lt;p&gt;Here is what I've tested:&lt;/p&gt;

&lt;p&gt;&lt;code&gt;https://rpc.ankr.com/xdc&lt;/code&gt; - This throws an error whenever I query block 1 (I suspect it’s a standard full node and trims historical state).&lt;/p&gt;

&lt;p&gt;&lt;code&gt;https://arpc.xinfin.network&lt;/code&gt; &amp;amp; &lt;code&gt;https://rpc.xdcrpc.com/&lt;/code&gt; - These seem to have the archive data, but they block my frontend requests (&lt;a href="http://localhost:5173"&gt;http://localhost:5173&lt;/a&gt;) due to CORS policies.&lt;/p&gt;

&lt;p&gt;Here is the exact error I get on the latter two:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;Access to fetch at 'https://arpc.xinfin.network/' from origin 'http://localhost:5173' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;My questions:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;Are there any free, public Archive RPC nodes available for XDC that support frontend/CORS requests?&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;If free options aren't available, are there any recommended paid providers that guarantee genesis block queries and allow custom origin headers?&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Thanks in advance for any recommendations!&lt;/p&gt;
