Query xAPI statements from a Learning Record Store using GET /statements with filter parameters

Steps
Call GET {endpoint}/statements with the required X-Experience-API-Version header set (e.g. 1.0.3).
Filter results using the agent, verb, activity, registration, since, and until query parameters — since returns statements stored after the given timestamp (exclusive) while until returns statements stored at or before it (inclusive).
Broaden matches with the boolean related_activities and related_agents parameters (both default false) to include context-referenced activities/agents and sub-statements.
Shape the response with format (ids, exact, or canonical; default exact) and cap results with limit (0 means the server's maximum); set ascending=true to reverse the default newest-first ordering.
Page through large result sets by following the more IRL returned in the StatementResult object, treating it as an opaque link rather than parsing it, valid for at least 24 hours.
Known gotchas
statementId or voidedStatementId cannot be combined with any other filter parameter except attachments or format — the LRS must reject that combination with 400 Bad Request.
An empty result set still returns 200 OK with an empty statements array, not a 404.
The more IRL returned for pagination is relative (excludes scheme, host, and port) and shouldn't be interpreted or reconstructed by the client — just follow it as-is.
