litellm - 💡(How to fix) Fix Agents page can hit 422 from /key/list page size limit [1 pull requests]

Summary

The Agents dashboard can fail while fetching key metadata because the UI calls /key/list with a page size larger than the backend accepts.

Symptom

A downstream deployment observed the Agents page request failing with 422 Unprocessable Content for:

GET /key/list?page=1&size=500&return_full_object=true&include_team_keys=true&include_created_by_keys=true

The backend route validates size with a maximum of 100, so size=500 is rejected before the key-list response can be returned.

Fix PR

PR: https://github.com/BerriAI/litellm/pull/28578

The PR:

• changes the dashboard key lookup page size to 100
• paginates /key/list until all visible agent keys are found or all pages are exhausted
• adds regression coverage for the page size and pagination behavior
• keeps dependencies and lockfiles unchanged

Current PR status at the time of filing:

• GitHub Actions pass
• Veria AI - PR Review passes
• PR is mergeable
• local npm audit signatures passed
