Point the client at the keyless endpoint and use three tools.</p> <h2> 1. Connect </h2> <p>Remote MCP URL:</p> <p><code>https://api.awesomevideoeditor.com/mcp</code></p> <p>Docs / Cursor / Claude recipes: <a href="https://awesomevideoeditor.com/mcp" rel="noopener noreferrer">awesomevideoeditor.com/mcp</a></p> <p>Many clients that only speak JSON on <code>initialize</code> / <code>tools/list</code> work against this endpoint (Streamable HTTP + content negotiation).</p> <h2> 2. Create a free trial key </h2> <p>Call <code>create_key</code> (or use the anonymous REST path). You get welcome credits once per network — enough to try a short clip. No email wall for the agent path.</p> <h2> 3. Caption </h2> <p>Call <code>caption_video</code> with a public MP4 URL. Live sample we keep online:</p> <p><code>https://awesomevideoeditor.com/samples/cc0-interview-es.mp4</code></p> <p>You get back job status, then downloadable MP4 (styled burn-in) + SRT/VTT/JSON transcript. Pricing is live at <code>/v1/pricing</code> (currently 5 credits per audio minute for captions; +2 with translate).</p> <h2> n8n </h2> <p>If you automate in n8n instead of an agent, there is an importable workflow (core nodes only, no key baked in):</p> <p><a href="https://awesomevideoeditor.com/integrations/n8n" rel="noopener noreferrer">Auto captions in n8n</a></p> <h2> Why this exists </h2> <p>Most caption SaaS is UI-first. Agents need: a tool list, a key they can mint, and a real video URL that is not <code>example.com</code>. Happy to answer MCP / OAuth / billing questions in the comments — I'm the maker.</p> ai video api mcp
