Kie.ai vs CloseRouter

Kie.ai and CloseRouter get lumped together as “another AI API”. They sit on different layers. Kie is one key for video, images, and audio (Kling, Veo, async createTask). CloseRouter is an LLM gateway for agents: chat/completions, /messages, Claude Code, Codex.

First the difference. Then how Kie actually works, so the comparison is not empty.

Sources: Getting Started, Market, recordInfo, Claude + kie, kie.ai.

What Kie.ai is

Their landing copy: one API to video, image, music, and LLM models, “same models, better rates”. FAQ: do not integrate each vendor separately; one workflow and competitive pricing.

It is a reseller plus a job layer. Not a foundation model, and not a gateway whose main path is sync chat.completions across hundreds of text models.

Typical user: covers, previews, short clips, “prompt → file”. Chat exists, but it is one Market shelf, not the product center. Flow on their site: pick a model → async request → webhook or polling.

What is in Market

From their market docs:

Images. Flux-2, Google Imagen, Ideogram, Qwen, Grok Imagine, Recraft, Topaz; the site also lists GPT Image 2 and Nano Banana (Gemini Flash Image).

Video. Kling (including 3.0: text/image-to-video, multi-shot, native audio), Sora 2, ByteDance / Seedance, Hailuo, Wan, Grok Imagine Video; the landing also shows Veo 3.1.

Audio. ElevenLabs. The site also lists Suno.

Chat. Gemini has a per-model path /…/v1/chat/completions. Claude Code is a separate host: https://api.kie.ai/claude. The live list is only on Market. They add models once they consider them stable. Each page has a Playground.

How the API works

Almost every Market model is async. HTTP 200 on create means “task accepted”, not “the clip is ready”.

Shared shape (quickstart):

Authorization: Bearer YOUR_API_KEY
POST https://api.kie.ai/api/v1/jobs/createTask
GET  https://api.kie.ai/api/v1/jobs/recordInfo?taskId={taskId}

Or callBackUrl and a webhook.

Balance: GET https://api.kie.ai/api/v1/chat/credit.

Do not put the key in frontend code. File uploads use a different host (kieai.redpandaai.co in their upload docs) — not api.kie.ai.

Minimal example. Take input fields from the model page; this is a skeleton, not a universal Kling schema:

curl -X POST "https://api.kie.ai/api/v1/jobs/createTask" \
  -H "Authorization: Bearer $KIE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kling-3.0/video",
    "callBackUrl": "https://your.example/hooks/kie",
    "input": {
      "prompt": "Studio product shot, slow camera push-in"
    }
  }'

The response is a taskId. Then poll or wait for the callback.

Task states

From Get Task Details:

• waiting
• queuing
• generating
• success — URLs in resultJson (usually resultUrls)
• fail — failCode / failMsg

Their advice: webhooks in production; backoff 2–3s; stop after 10–15 minutes; download immediately — “URLs typically expire after 24 hours”. Getting Started also mentions ~14 days of media retention. The docs disagree, so do not assume a link lives for weeks.

Also creditsConsumed, costTime. Sora2 may include progress 0–100.

Handle 401, 402 (credits), 404, 408 (upstream silent >10 min), 429, 455 (maintenance), 501 (generation failed). Failed generations do not consume credits, per their FAQ.

Limits they document themselves

• Up to 20 new creates / 10 seconds (120/min). 429 is not queued.
• Credits do not expire (landing FAQ).
• Keys: limits, IP allowlist.
• Stability “may be slightly lower than official APIs” — Getting Started wording, a stated tradeoff. The landing also shows 99.9% uptime. We do not glue that into “they have a 99.9 SLA”.
• Support: Discord/Telegram from the dashboard; email as backup.

Prices: they compare against official on kie.ai/pricing and on the landing. Numbers move. Do not freeze a screenshot as fact.

“120,000+ developers” is their landing copy, not our benchmark.

Claude Code through Kie

Their guide: Claude Code + kie.ai.

After installing Claude Code they tell you not to log in with an Anthropic account. Check: claude, one message, then their logs page.

This is a third env dialect next to OpenRouter and CloseRouter. See the ANTHROPIC_BASE_URL post for the table.

Who Kie is for

Makes sense if you ship covers, clips, tracks, or want one wallet instead of five media dashboards.

A poor fit if you need a vendor SLA, a hard data region, or a sync agent over a git repo. The job API is not a drop-in for /v1/chat/completions.

Kie vs fal.ai / Replicate

Those are the real neighbors. fal is strong DX and inference. Replicate is easy weights and your own deploys. Kie is one wallet for popular closed media models plus a public “vs official” column.

If the pipeline already lives on fal, do not migrate for a blog post. If you want cheap Kling/Veo/Nano Banana behind one key, look at Market and live pricing.

Kie vs CloseRouter

You can keep both: Kie draws the frame, CloseRouter runs the agent. That is not “who has the cooler API”.

Getting started

1. Key: kie.ai/api-key.
2. Model and Playground on Market.
3. createTask from your backend.
4. Webhook or recordInfo.
5. Download the file into your own storage.

Docs: docs.kie.ai.

If you need an agent, not a clip: closerouter.dev/keys and bash <(curl -fsSL https://closerouter.dev/install.sh); the installer prompts for the key securely.

FAQ

Is Kie Kling? No. Kling is one Market model.

Why 200 with no file? 200 on create means the task exists. The file comes after success.

Can Kie replace OpenRouter / CloseRouter? Usually not for a chat agent. Yes for images and video.

Are they cheaper than official? That is how they position pricing. Check the model on the pricing page the day you buy.

How long does the URL live? One docs page says 24 hours, another says 14 days for media. Download immediately.
