Users can now experience the convenience of querying any Subgraph without the need for an API key. This is made possible through the recent addition of x402 payments support on The Graph Gateway, which allows you to seamlessly use USDC on Base for your transactions. To set everything up, simply execute the command npm install @graphprotocol/client-x402. For further information and detailed instructions, please refer to the official documentation provided at https://thegraph.com/docs/en/subgraphs/guides/x402-payments/
