# Get Execution Query Profile (explain-on-execute read path)

`GET /v1/retrievers/{retriever_id}/executions/{execution_id}/profile`

## Request

- Base URL: `https://api.mixpeek.com`
- URL: `https://api.mixpeek.com/v1/retrievers/{retriever_id}/executions/{execution_id}/profile`
- Auth: HTTP bearer and API key in header `X-Namespace`

Return the query profile for a PAST execution, by execution_id — the same plan that `explain=true` returns inline at execute time, read back later. Contains per-stage timings + input/output counts, MVS execution stats, the optimizer summary, and (as it is wired) the shard ExecutionTrace (chosen legs, fusion, push-downs, nprobe, served/shadow planner). Reads the query_profile stored on the execution's record in the mxp_retriever_executions collection. Returns 404 if the execution has no captured profile. This is the queryable, Studio-friendly counterpart to inline explain.

## Path parameters

- `retriever_id` string, required: Retriever ID or name.
- `execution_id` string, required: Execution identifier.
