List all llm analytics personal spend

Return a structured personal LLM spend analysis for the requesting user. Pass date_from / date_to (absolute like 2026-04-23 or relative like -7d) to bound the window — defaults to the last 30 days, max 90 days. The product=<ai_product> query param is required and scopes the tool / model / day / trace breakdowns to a single product; supported values: posthog_code. by_product is always returned for cross-product visibility. by_day returns a day-ascending spend series for the scoped product. Pass bucket_minutes (5, 15, 30, or 60; the window may span at most 600 buckets) to additionally get by_bucket, a time-ascending series with per-bucket cost split into uncached input / output / cache read / cache creation components. Use refresh=true to bypass the 5-minute response cache.

Create llm analytics summarization

Generate an AI-powered summary of an LLM trace or event.

This endpoint analyzes the provided trace/event, generates a line-numbered text representation, and uses an LLM to create a concise summary with line references.

Two ways to use this endpoint:

  1. By ID (recommended): Pass trace_id or generation_id with an optional date_from/date_to. The backend fetches the data automatically. summarize_type is inferred.
  2. By data: Pass the full trace/event data blob in data with summarize_type. This is how the frontend uses it.

Summary Format:

  • Title (concise, max 10 words)
  • Mermaid flow diagram showing the main flow
  • 3-10 summary bullets with line references
  • "Interesting Notes" section for failures, successes, or unusual patterns
  • Line references in [L45] or [L45-52] format pointing to relevant sections

The response includes the structured summary, the text representation, and metadata.
