Use Stand-in from your own AI

1. Connect

Claude, ChatGPT and other chat apps

Add a custom connector and paste https://standinai.com/api/mcp. Sign in to Stand-in when asked and press Allow. No key needed.

• claude.ai: Settings → Connectors → Add custom connector.
• ChatGPT: Settings → Connectors (developer mode) → Create, then choose OAuth.

Coding agents (Claude Code, Codex, opencode and others)

Make a key in Account → Agents. Pick “Read only” or “Can make videos”, then copy it straight away: it’s shown once.

Claude Code:

claude mcp add --transport http standin https://standinai.com/api/mcp \
  --header "Authorization: Bearer si_live_…"

Codex (~/.codex/config.toml, with the key in the STANDIN_API_KEY environment variable):

[mcp_servers.standin]
url = "https://standinai.com/api/mcp"
bearer_token_env_var = "STANDIN_API_KEY"

opencode (opencode.json):

{
  "mcp": {
    "standin": {
      "type": "remote",
      "url": "https://standinai.com/api/mcp",
      "headers": { "Authorization": "Bearer si_live_…" }
    }
  }
}

Anything else that speaks MCP over HTTP: use the address above and send the header Authorization: Bearer si_live_….

2. What your AI can do

3. A typical request

Say “Make a Stand-in video from clip.mp4 with my usual Stand-in”. The AI will:

1. check your plan and Stand-ins (get_account, list_standins);
2. get an upload link (get_upload_url): you open it on your phone or computer and pick the clip, or a coding agent uploads the file itself;
3. ask for the price with create_video and dryRun, and show it to you;
4. start the video once you say yes (create_video);
5. check every 15 to 30 seconds until it’s ready (get_video), then give you the download link. Links last an hour; ask again for a fresh one.

We measure the clip’s length ourselves, so the price is always for the real length.

Two shortcuts: if the clip is a video file on the web, give your AI its link (sourceUrl, a direct link to an mp4 or mov up to 400 MB; not a TikTok, YouTube or Instagram page) and skip the upload. And to use only a part, say “from 6 seconds to 21 seconds” (startS and endS): the price and the video are for that part. Asking again for the same clip with another quality level, voice or captions makes a new video; the same settings twice within an hour are one video, charged once.

4. Prices and limits

Exactly the app’s prices. 1 credit is 1 cent, and each video uses credits for every started 15 seconds. A 30-second video is 399 credits on Lite ($3.99), 749 on Standard ($7.49), 971 on Pro ($9.71). A 30-second Pro video is 971 credits ($9.71). Clips can be up to 10 minutes.

• Credit packs: $10 for 1,000 credits, $25 for 2,500 credits, $50 for 5,000 credits, $100 for 10,000 credits. Credit packs never expire.
• Starter: $19.99 a month for 2,100 credits (about 4 videos of 15 seconds). Unused plan credits roll over to the next month.
• Creator: $49.99 a month for 5,500 credits (about 11 videos of 15 seconds). Unused plan credits roll over to the next month.
• Pro: $99.99 a month for 11,000 credits (about 22 videos of 15 seconds). Unused plan credits roll over to the next month.
• Lite: 399 credits per 30 s.
• Standard: 749 credits per 30 s.
• Pro: 971 credits per 30 s.
• Lite and Pro include Sharp HD on clips up to a minute. Standard is our default, and you can add it to a finished video.
• Auto captions 50 credits (included on Creator and Pro) per started 30 seconds.
• Voice swap 50 credits (included on Creator and Pro) per started 30 seconds.
• Sharp HD on a finished video 111 credits per 15 s per started 30 seconds.
• Green screen 100 credits per started 30 seconds.

If we can’t finish a video, its credits come back to you automatically. Limits, shared with the app: 30 new videos and 60 uploads an hour, and 600 calls an hour from agents.

5. Keeping your account safe

• We only store a fingerprint of each key, never the key. If you lose one, revoke it and make a new one.
• Anyone with your key can use your account within what you allowed, so keep it out of shared files and repositories.
• Pick “Read only” unless the agent needs to make videos. Permissions you can give:
  • See your plan, videos left and wallet balance
  • See your Stand-ins
  • Make new Stand-ins (counts toward your monthly limit)
  • See your videos and download them
  • Upload clips and make videos (uses your credits)
• Revoke a key or disconnect an app any time in Account → Agents. It stops working straight away.
• Agents can’t change your plan, password or payment details.
