FAQ
How do I use the LMArena List Available Models API?
Send a POST request to https://api.sandbase.ai/v1/api/lmarena/list-available-models with your SandBase API key in the Authorization header (Bearer) and the parameters as a JSON body. You can also try it in the Playground on this page without writing code.
How much does the LMArena List Available Models API cost?
$0.01 per call. Every organization gets 100 free calls per UTC day, shared across eligible SandBase APIs including this one; after that each call is billed at this price from your SandBase balance. There is no subscription.
What parameters does the LMArena List Available Models API accept?
LMArena List Available Models takes no input parameters; send an empty JSON body.
What does the LMArena List Available Models API return?
A JSON result. This endpoint runs asynchronously, so the response tells you how to fetch the finished result.
Do I need a LMArena developer account or API key?
No. LMArena List Available Models runs through SandBase, so one SandBase API key covers this endpoint and every other API and model in the catalog. You do not need to apply for LMArena API access separately.
