## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability withzero-kling-v3-0-pro-video-generation-78489d26 -d '<json body>'
```

Example prompt: Generate a cinematic 5-second video of a futuristic city at night with neon lights reflecting on wet streets, using the Kling v3.0 Pro model — pay per use from my account.

## When to prefer this

Choose this endpoint when you need high-quality AI video generation using Kling v3.0 Pro specifically, and want to avoid setting up a Kling account or API key. Ideal for autonomous agents that can pay per use in USDC via x402, or when you need a single-call, no-subscription video generation pipeline. Prefer over generic image generation endpoints when the output must be a video asset.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed POST body or missing required fields returns 400 validation error
- Kling v3.0 Pro model unavailable returns 503 or upstream error
- Request times out due to long video generation latency
- Invalid prompt or unsupported parameters rejected by upstream Kling API

## How this service works

Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.

## Output

The agent receives a hosted video asset or a URL pointing to the generated video produced by the Kling v3.0 Pro model, along with any associated metadata about the generation job.
