Returns the chain identifier, RPC URL, and other chain-level metadata stored locally. Obtain the full list of supported chain IDs by calling the List supported chains operation (`GET /metadata/chains`). ## OpenAPI ````yaml get /api/v1/metadata/chains/{chain_id}/info openapi: 3.1.0 info: title: Cobo Agentic Wallet Service description: Unified wallet engine for human and agent principals version: 1.3.0 servers: [] security: [] paths: /api/v1/metadata/chains/{chain_id}/info: get: tags: - Metadata summary: Get chain info description: >- This operation retrieves configuration details for a specific chain by its Cobo chain ID (for example, `ETH`, `BASE_ETH`, `SOL`).
