Filip Sinitsin e81dd348a4 fix(proxy)!: log and bill Responses-style bodies sent to /cursor/chat/completions (#30277) ... * fix(proxy): restore spend logging for /cursor/chat/completions (#30126) The /cursor/chat/completions route processes requests through the Responses API pipeline, but _get_metadata_variable_name did not treat it as a litellm_metadata route. Proxy auth metadata therefore landed in the user-facing metadata param, so the spend tracking callback saw user_api_key=None and silently skipped the SpendLogs write. Add the route to LITELLM_METADATA_ROUTES and cover it with regression tests. * test(proxy): pin provider metadata and key billing on /cursor/chat/completions A Responses-format body on the Cursor route now sends OpenAI only the metadata the client sent and writes a spend row that bills the key. The chat-body branch, which this fix also moves onto litellm_metadata, still bills the key with its team and request tags. The scripted chat reply gets a unique id per test, since a shared id let only the first spend row per database land * fix(proxy): pick the Cursor route's metadata field from the body shape A Responses-style body on /cursor/chat/completions keeps proxy metadata in litellm_metadata, the same as /v1/responses, while a Chat Completions body keeps metadata, the same as /v1/chat/completions. Adding the whole route to the internal-metadata list let a client's chat-body tags replace the key's tags in spend logs and skip tag budgets. * fix(proxy): keep get_metadata_variable_name callable with only the request * fix(proxy): check client tags against tag budgets and read agent limits from litellm_metadata on Responses bodies A Responses-style body on /cursor/chat/completions now keeps its proxy fields in litellm_metadata, so the pre-call tag budget check and the v3 agent rate limiter stopped seeing the client's metadata.tags and the x-litellm-agent-id value. The pre-auth tag check now merges the caller's metadata.tags into the selected metadata field, sharing one helper with request setup, and the limiter reads agent_id from either field * fix(proxy): check client tags sent in a JSON-string metadata against tag budgets on Responses bodies * fix(proxy): answer 422, not 500, when a budget rejects a Responses body whose metadata is a JSON string * fix(proxy): keep key guardrails, metadata type errors and failure-row client details on Responses-style bodies --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>		2026-10-30 00:18:15 -07:00
