Veo 3 API: Prompts and scripts over one endpoint

Prerequisites and Authentication

Before making your first request, ensure you have a valid API key. Sign up on the Get API key page with just an email and password. You receive immediate access to $0.50 in trial credit, valid for 7 days, with no credit card required. For production workloads, top up with at least $10 to secure continued access.

Our base URL is https://api.veo3apis.com/v1. Include your API key in the Authorization header as a Bearer token. This endpoint is fully OpenAI-compatible, meaning you can use standard SDKs by pointing them to our base URL.

Basic Chat Completion

Send a standard POST request to /v1/chat/completions to generate text. The model ID is "uncensored". This returns the full response in a single JSON object, ideal for simple prompt generation or script writing tasks where you don't need real-time updates.

Python SDK Integration

Use the official OpenAI Python SDK for clean integration. Configure the client with our base URL and your API key. This approach simplifies error handling and token counting for your multimodal pipelines.

Node SDK Integration

For JavaScript/TypeScript projects, the OpenAI Node SDK works out of the box. Point the client to our base URL. This is useful for server-side script generation or post-processing steps in your Veo 3 workflow.

Streaming Responses (SSE)

For faster perceived latency, enable streaming by setting stream: true. The API returns a Server-Sent Events (SSE) stream of partial responses. This allows your application to display tokens as they are generated, which is critical for long script generation or complex reasoning tasks.

Limits, Errors, and Context

Your requests are subject to a rate limit of 300 requests per minute per key. If you exceed this, you receive a 429 error. Authentication failures return 401, and insufficient credit returns 402. The context window is 100,000 tokens total (prompt + completion). Ensure your payloads stay under 8 MB. The only hard content limit is sexual content involving minors, which is always blocked.

cURL

Copycurl https://api.veo3apis.com/v1/chat/completions \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "uncensored",
    "messages": [{"role": "user", "content": "Write a blunt product review of a cheap VPN."}]
  }'

Python

Copyfrom openai import OpenAI

client = OpenAI(base_url="https://api.veo3apis.com/v1", api_key="YOUR_KEY")

resp = client.chat.completions.create(
    model="uncensored",
    messages=[{"role": "user", "content": "Summarise this thread without softening it."}],
)
print(resp.choices[0].message.content)

Node.js

Copyimport OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.veo3apis.com/v1", apiKey: process.env.API_KEY });

const resp = await client.chat.completions.create({
  model: "uncensored",
  messages: [{ role: "user", content: "Draft a villain monologue for my game." }],
});
console.log(resp.choices[0].message.content);

Streaming

Copystream = client.chat.completions.create(
    model="uncensored",
    messages=[{"role": "user", "content": "Tell the story in second person."}],
    stream=True,
)
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
