When to use this
Use this endpoint when you have anllm_id saved on an agent configuration or in your own database and you need to resolve it into a human-readable label, confirm the model is still active, or check what features the model supports before sending an agent update.
- Agent build UIs typically fetch this when rendering the LLM selection for an already-saved agent so the dropdown can display the correct provider, name, and capability badges.
- Migration tooling that retires a deprecated model uses this to confirm the target model still exists before bulk-updating agents.
- Cost-aware dashboards read the provider and tier from this endpoint to attribute spend per model in internal reports.
