🚀 Why This API Is Different

Most transcript tools stop at “just text”.
This one is built for real production workflows.

• ⚙️ Developer-first JSON structure
• 🧩 Segment-level timestamps, not just plain text
• 🤖 AI-agent ready — perfect for chaining with LLMs
• 📈 Built for scale, not manual use
• 💰 Pay-per-result pricing, no wasted cost

You get data, not screenshots or scraped HTML.

---

📝 Notes

• Only public Bilibili video URLs are supported
• Transcripts are generated via automatic speech recognition
• Accuracy may vary depending on audio quality, accents, and background noise
• This API focuses on URL-based extraction only (no search mode)
