Endpoint
POSThttps://gpt55.558686.xyz/v1/tools/summarize/miniWhen to prefer
Choose this endpoint when you need fast, cheap summarization for high-volume triage tasks like support tickets, short notes, or quick digests, and cost is a priority. It uses the mini model tier which is optimized for low-cost, short-output summaries rather than deep reasoning or long-form generation. Prefer over full-model endpoints when 4096 tokens of output is sufficient and per-call cost must stay at or below $0.0025 USDC.
Side effects
- Input text exceeds 700,000 character limit — request rejected

- Payment not provided or insufficient USDC — 402 payment required error
- Empty or missing text field — validation error
- Temperature out of 0–2 range — request rejected
