# LLM request statistics

`GET /v1/default/banks/{bank_id}/llm-requests/stats`

## Request

- Base URL: `https://hindsight.vectorize.io` (the document declares no server; this is the origin it was published from)
- URL: `https://hindsight.vectorize.io/v1/default/banks/{bank_id}/llm-requests/stats`
- Auth: none declared
- TypeScript: <https://skmtc.dev/vectorize/apis/hindsight-http-api/docs/v1/default/banks/:bank_id/llm-requests/stats/get.ts> (a function with typed inputs; its response is checked against the schema)

Get LLM request counts grouped by time bucket and status for charting. Only requests within HINDSIGHT_API_LLM_TRACE_RETENTION_DAYS are kept, so a period longer than `retention_days` (in the response; null = kept forever) only covers the last `retention_days`.

- `operation` string, nullable: Filter by operation
- `call_type` 'llm' | 'embedding' | 'rerank' | 'decision', nullable: Filter by kind of model call: llm, embedding, rerank or decision
