AI_APICallError: 402 Payment Required — Insufficient balance or daily spend cap reached

What it means
Tokentide refused the request before running it because your prepaid balance ran out or your key hit its daily spending cap.
Likely causes
  • The low-cap development key reached the daily limit you set for safety.
  • Your Tokentide account balance needs a top-up at tokentide.app/app/billing (from $10).
Prevention
Enable balance alerts on tokentide.app/app/billing and always configure the Vercel AI Gateway fallback.

Copy for your agent

Tokentide returned `402`. Verify that our AI client has `maxRetries: 0` on Tokentide and automatically falls back to the Vercel AI Gateway on 402 so users aren't interrupted while I check my balance or cap.
