Technical Implementation: Using the Sora API

Let's dive into the practical aspects of implementing Sora video generation in your applications.

1. Authentication and API Keys

To authenticate with the API, you'll need to obtain valid API credentials:

• Official OpenAI API: Standard OpenAI API keys with Sora scope
• laozhang.ai API: Register at https://api.laozhang.ai/register/?aff_code=JnIT to receive immediate API keys with free credits

2. Basic API Request Structure

The Sora API follows RESTful principles with a JSON request/response format:

hljs javascript
// Basic structure for Sora video generation request
const response = await fetch("https://api.openai.com/v1/videos/generations", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_KEY"
  },
  body: JSON.stringify({
    model: "sora-1",
    prompt: "A serene mountain landscape with a flowing river and eagles soaring overhead",
    duration: "15s",
    dimensions: "1920x1080"
  })
});

const data = await response.json();
const videoUrl = data.data[0].url;

When using laozhang.ai transit API, the structure remains identical, only the base URL changes:

hljs javascript
// Same structure, different base URL
const response = await fetch("https://api.laozhang.ai/v1/videos/generations", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_LAOZHANG_API_KEY"
  },
  body: JSON.stringify({
    model: "sora-1",
    prompt: "A serene mountain landscape with a flowing river and eagles soaring overhead",

Effective Prompt Engineering for Sora

The quality of generated videos heavily depends on the prompts provided. Here are some proven strategies:

1. Prompt Structure Template

Follow this general template for optimal results:

[Scene description] + [Visual style] + [Camera movement] + [Lighting] + [Technical specifications]

Example:

A golden retriever running through a sunlit forest. Cinematic film style with shallow depth of field. Slow motion tracking shot following the dog. Warm afternoon lighting with sun rays through trees. Photorealistic 4K quality.

2. Specifying Visual Elements

Be explicit about important visual elements:

• Time of day: "at sunset", "during morning fog"
• Weather conditions: "light rain", "snow falling"
• Camera angles: "aerial view", "tracking shot", "close-up"
• Movement: "slow motion", "time-lapse"
• Style references: "like a Wes Anderson film", "documentary style"

3. Common Pitfalls to Avoid

Based on developer feedback, these prompt issues commonly lead to subpar results:

• Overly complex scenes with too many actions or subjects
• Contradictory elements that confuse the model
• Vague descriptions that lack specific visual guidance
• Text/number rendering requests (Sora struggles with text)
• Exact human faces or specific celebrity likenesses

Limitations and Future Developments

Understanding current limitations helps set realistic expectations:
