During April 2025, this developer updated the alchemyplatform/docs-openapi-specs repository by defining the Wallet CreateSession API endpoint using the OpenAPI 3.1.0 specification. The work involved designing the complete schema in YAML, including detailed request parameters, request body, and response structures to support secure wallet session creation through the Alchemy API. By aligning the documentation with repository standards and OpenAPI versioning, the update closed a key API design gap and enabled smoother client SDK integration. This contribution improved overall API coverage for wallet session lifecycle management, supporting future wallet feature rollouts and enhancing developer integration workflows without introducing new bugs.
