Worked on the MetaMask/metamask-docs repository to enhance the reliability and correctness of API documentation, focusing on the StarkNet JSON-RPC API. Addressed a documentation bug by removing trailing commas from JSON examples, which previously caused invalid JSON and led to parse errors for developers integrating with the API. This targeted fix improved the accuracy of API call samples, making them copy-paste friendly and reducing friction for downstream integrations. Utilized Markdown for documentation updates and applied API design principles to ensure clarity and usability. The work emphasized attention to detail and contributed to a smoother onboarding experience for developers referencing the documentation.
