ReelWords Captions
Generate stylized captions for videos using the ReelWords Caption API: create a caption render job, poll until complete, then download the rendered output.
1) Create a ReelWords account + API key
Sign up / log in: https://reelwords.ai Open the account menu (top-right) β API Keys β New key Copy the key (it will look like rw_...).
2) Provide the API key to OpenClaw
Provide the API key to the process as REELWORDS_API_KEY. Common options: Set REELWORDS_API_KEY as an environment variable (best when running the script directly) If you run via OpenClaw/Clawdbot, store it in ~/.clawdbot/openclaw.json under skills.entries.reelwords-captions.env so the runtime can populate env vars for the skill. Option A: environment variable export REELWORDS_API_KEY="rw_..." Option B: openclaw.json (recommended) Edit ~/.clawdbot/openclaw.json and add an entry: { "skills": { "entries": { "reelwords-captions": { "enabled": true, "env": { "REELWORDS_API_KEY": "rw_..." } } } } }
Security note
Treat your API key like a password: donβt commit it to git donβt paste it into public chats rotate it in ReelWords if you suspect it leaked
Usage
Base URL: https://api.reelwords.ai You can use either the included helper script (simplest), or call the REST endpoints directly.
Option 1: All-in-one helper script (create β poll β download)
From this skill directory: python3 scripts/reelwords_caption_job.py \ --video-url "https://cdn.reelwords.ai/sample.mp4" \ --style-id "style1" \ --add-emojis \ --max-words-per-line 6 \ --position-y 82 \ --font-size 54 \ --highlight-color "#FFD803" \ --hook-color "#FF5CAA" \ --out captioned.mp4 Notes: The script prints the final job JSON to stdout. Download logic: prefers result.downloadUrl when present otherwise falls back to GET /api/v1/caption-jobs/{id}/video (which typically redirects to a signed URL)
Option 2: Raw API examples (curl)
1) Create job curl -sS https://api.reelwords.ai/api/v1/caption-jobs \ -H "x-api-key: $REELWORDS_API_KEY" \ -H "content-type: application/json" \ -d '{ "videoUrl": "https://cdn.reelwords.ai/sample.mp4", "preferences": { "style": { "styleId": "style1" } } }' Response includes an id (save it as $JOB_ID). 2) Poll status curl -sS https://api.reelwords.ai/api/v1/caption-jobs/$JOB_ID \ -H "x-api-key: $REELWORDS_API_KEY" \ -H "accept: application/json" Poll until status becomes completed (or the response includes failureReason/failureMessage). 3) Download rendered video Preferred (when present): download from result.downloadUrl Fallback (works in most tenants): curl -L https://api.reelwords.ai/api/v1/caption-jobs/$JOB_ID/video \ -H "x-api-key: $REELWORDS_API_KEY" \ -o captioned.mp4
Workflow (high level)
Create caption job: POST /api/v1/caption-jobs videoUrl (required) preferences.style.styleId (required) optional preferences (emojis, max words per line, colors, font sizing, etc.) Poll job status: GET /api/v1/caption-jobs/{id} until: completed: result.downloadUrl is usually present (downloadable) failed: failureReason / failureMessage present Download: result.downloadUrl, or GET /api/v1/caption-jobs/{id}/video (redirects to a signed URL)

API summary + curl examples: references/api.md
Notes
Auth header is x-api-key: <token>. If you hit usage limits, treat HTTP 402 as βout of credits / limit reachedβ and surface the response cleanly. If ReelWords adds new fields, prefer passing them through in the JSON payload rather than hardcoding assumptions.
