# Implementation Guides

## Docs

- [Authentication](https://docs-dev.ltx.io/authentication.md): Understand how to securely authenticate with the LTX API. Follow step-by-step instructions for generating and managing API keys safely.
- [Supported Models](https://docs-dev.ltx.io/models.md): Explore all supported LTX models for text-to-video, image-to-video, and other generation tasks. Learn their capabilities and best use cases.
- [LTX-2.5](https://docs-dev.ltx.io/models/ltx-2-5.md): LTX-2.5 supports text-to-video, image-to-video, and audio-to-video in portrait and landscape — ltx-2-5-fast and ltx-2-5-pro up to 4K.
- [LTX-2.3](https://docs-dev.ltx.io/models/ltx-2-3.md): LTX-2.3 (ltx-2-3-fast, ltx-2-3-pro) supports text-to-video, image-to-video, audio-to-video, retake, and extend at up to 4K.
- [Input Formats](https://docs-dev.ltx.io/input-formats.md): Complete guide to providing image and video inputs to the LTX API. Learn about upload methods, supported formats, codecs, and constraints.
- [Prompting Guide](https://docs-dev.ltx.io/api-documentation/implementation-guides/prompting-guide.md): LTX prompt-writing guidance: shot, action, camera, and audio structure; LTX-2.5 multi-shot prompts; and local prompt-enhancer guidance.
- [Migrate from V1 to V2](https://docs-dev.ltx.io/migrate-v1-to-v2.md): Migrate an LTX API integration from synchronous V1 video generation endpoints to the asynchronous V2 job API.
- [Async Jobs](https://docs-dev.ltx.io/async-jobs.md): Learn how to use the LTX async (V2) API — submit a generation request, poll for status, and retrieve the output. Covers the full job lifecycle, status values, result format, and retention policy.
- [Rate Limits](https://docs-dev.ltx.io/rate-limits.md): Review LTX API rate limits and request quotas. Learn how to optimize your usage and avoid throttling with efficient request management.
- [Error Handling](https://docs-dev.ltx.io/errors.md): Learn how LTX communicates errors and how to handle them gracefully. Includes error codes, response examples, and best practices.
- [Debugging Requests](https://docs-dev.ltx.io/debugging.md): Find out how to debug and troubleshoot API requests in LTX. Includes tips for logging, inspecting responses, and identifying common issues.
