## Verdicts

**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.

**Runway API.** OpenAPI 3.1, llms.txt and Markdown copies of every docs page. Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog.

## Before you call either

### 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

### Runway API

1. Send `X-Runway-Version: 2024-11-06` on every request or it fails
2. Use the SDK's wait-for-output helper or poll GET /v1/tasks/{id} until SUCCEEDED or FAILED
3. Don't retry a SAFETY.* failure unchanged. It's moderation, not an outage
4. Take model IDs from the models page, not memory. Two were removed without notice on 2026-07-30
5. Copy outputs to your own storage. URLs expire within 24 to 48 hours
