Verdicts

Kling AI API

Kling 3.0 from $0.084 a second, with audio from $0.126. Developer docs, API terms and pricing render only with JavaScript.

PixVerse API

V6 at about $0.04 a second at 720p, with audio and clips up to 15 seconds. Plan prices and the dollar value of a credit sit on a JavaScript-only billing page.

Before you call either

Kling AI API

  1. Sign a JWT (HS256) with iss set to your AccessKey and a 30 minute exp, then send it as a bearer token
  2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it
  3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds
  4. Take model IDs and prices from kling.ai/llms.txt. The HTML docs need JavaScript
  5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls

PixVerse API

  1. Generate a new UUID for Ai-trace-id on every new submit. Reuse it only to fetch the same job again
  2. Poll the result endpoint. Status 1 is done, 5 generating, 7 moderation failure, 8 failed
  3. Moderate prompts before calling. Repeated status 7 results can suspend the key
  4. Use model v6 or c1 for new work. Older model tables still sit in the docs
