Hi team,
Getting consistent HTTP 500 on all requests to the v0 Platform API.
Endpoint: POST https://api.v0.dev/v1/chat/completions
Plan: Premium with usage-based billing enabled
Tested all 3 models (v0-1.0-md, v0-1.5-md, v0-1.5-lg), minimal request body, via curl + Node.js + AI SDK.
All return: {“success”:false,“error”:“Unknown error”} HTTP 500
Example: curl -X POST https://api.v0.dev/v1/chat/completions -H “Authorization: Bearer KEY” -H “Content-Type: application/json” -d {“model”:“v0-1.5-md”,“messages”:[{“role”:“user”,“content”:“Say hello”}]}
The v0 chat UI works fine. Only the API returns 500.
Similar to issue #17904 (Aug 2025) but appears to have regressed.
Thanks!
