Worked on implementing and documenting the Alchemy Bundler API specifications in the alchemyplatform/docs repository, focusing on enabling seamless client integrations through clear JSON-RPC methods and server endpoints. Leveraged YAML for precise API documentation, ensuring that both v6 and v7 user operation versions are supported and accurately reflected in updated example outputs. This work established stable multi-version compatibility, improving interoperability for downstream applications and reducing integration risk. By aligning the documentation with evolving API semantics, the developer set a foundation for smoother upgrades and easier maintenance, demonstrating a strong grasp of API documentation practices and versioned protocol design.
