Module: External API Interface (Views & Pagination)

[memplethee-lab]

Provide an External API Interface module to expose standardized read/write contract endpoints for off-chain integrations.

Direction:

• Design a set of view functions and standardized response structs for common queries (balances, permissions, metadata).
• Implement input validation and pagination for list responses.
• Provide examples for JSON-RPC/graphQL-friendly patterns and off-chain indexing compatibility.

Acceptance criteria:

• API Interface module added with documented view functions and paginated list endpoints.
• Tests cover pagination correctness, input validation, and gas usage for view calls.
• README includes example API payloads and guidelines for building indexers against the contract events and views.
