429 Too Many Requests with error code insufficient_quota — distinguishable from rate_limit type Fix OpenRouter rejection when sending images to text-only models (e.g., deepseek-v4-pro); need to detect modality mismatch before tool invocation Includes evidence for OpenRouter troubleshooting demand.
HTTP 404: No endpoints found that support image input Developer discovers unexpectedly high token usage in Claude Code, searching for causes beyond normal rate limits — specifically cache-related cost inflation Includes evidence for Claude Code troubleshooting demand.
Prompt cache broken — silently inflates costs 10-20x in Claude Code; downgrading helps Developer automating Claude Code encounters unexplained daily quota exhaustion, seeking explanation for silent retry behavior Includes evidence for Claude Code troubleshooting demand.
Rate-limit errors appear as generic failures triggering silent retry loops, draining daily budget in minutes Developer on paid Claude Code plan experiencing rapid quota drain, wants to understand why usage limits deplete so quickly and how to extend usage time Includes evidence for Claude Code troubleshooting demand.
