Vapi: production landmines and fixes

Voice-agent landmines: the Vapi API failures we hit running production missed-call and reception agents. Every entry is a failure we personally hit on billed client work, with the verbatim error, the fix, and the date we last verified it.

Landmines

• Vapi API 400: "property tools should not exist"
• Vapi API 403: "error code: 1010" on every request

Hit one of these on a client build? We fix and run these systems white-label for agencies. What we build →
