GET /v1/tool/spend served the Cost Optimization card with two raw queries
over LiteLLM_SpendLogToolIndex x LiteLLM_SpendLogs on every dashboard load;
the totals query's driving scan was all of SpendLogs in the window. Both
per-request tables reach 1M+ rows at customer scale, so the card cost
O(traffic) per view and had to be capped at 30 days.
The index writer also mined proxy_server_request.tools, i.e. tools DECLARED
in the request body, attributing each request's full spend to tools that
never ran; and all non-MCP mining ran against payload fields that are '{}'
unless store_prompts_in_spend_logs is enabled, so non-MCP coverage silently
depended on a privacy setting.
Now the spend writer builds a ToolUsageTransaction at request time from
invoked tools only, resolved by the shared get_tool_calls_from_response
normalizer so every response surface (chat completions, Responses API,
Anthropic Messages) is covered; the tool registry's response arm delegates
to the same owner. Transactions queue beside the spend-log queue and the
flush job writes index rows plus a new LiteLLM_DailyToolSpend rollup
(date, tool_name PK) in one transaction, retrying connection errors with
backoff (a failed batch commits nothing, so the retry cannot double-count)
and dropping the batch with an error log on anything else.
The endpoint aggregates in SQL: by_tool is the top TOOL_SPEND_TOP_TOOLS
tools by spend via group_by and daily covers only those tools, so the
response is bounded by days x TOOL_SPEND_TOP_TOOLS regardless of range or
tool-name cardinality; the 30-day clamp is gone. total_spend is dropped
from the response; it was never rendered and its deduplicated semantics
are not computable from a rollup. Spend-log retention deliberately does
not touch the rollup, so tool spend history outlives per-request rows.
