Hey Product Hunt! 👋 Autonomous agents keep hitting the same wall: you don't want an LLM freely generating prose when all you need is one of five predefined choices. Every routing decision meant either expensive reasoning tokens, fragile JSON parsing, or a custom classifier you had to train and host. decisionsapi.app is a practical guide to OpenAI's new Decisions API — a decision primitive that changes that: • Sub-150ms latency: benchmarked at ~142ms, built for real-time triage and agent loops • Zero-hallucination guarantee: the response is mathematically one of your declared choices — no regex, no parsing • Native text + vision input: route on messages, tickets, or screenshots alike • Cost-efficient: ~85% token-cost reduction vs. chat completions for constrained classification • Edge-ready: works directly in Cloudflare Workers for guardrails and moderation I put together quickstarts, cURL examples, benchmarks and architecture patterns (agent routing, content triage, visual verification, edge enforcement) so you can evaluate it in minutes, not hours. Try the quickstart and tell me which integration pattern you want covered next — happy to dig deeper on anything. 🚀
