challanx

All-in-one RTO, challan, RC lookups and media downloader features for ChallanX. Accepts a single input — a URL, a free-text message, or an image — and returns concise, actionable results (download links, summaries, or document analysis).

Use this skill to work with the ChallanX OpenClaw media API at https://challanx.in/openclaw/api.

Core rules

• Treat https://challanx.in/openclaw/api as the only public endpoint.
• Prefer file-like outputs with correct filenames and content types.
• When the upstream media is downloadable, return a real media file response such as mp4, mp3, jpg, png, webp, or octet-stream only as a last fallback.
• Avoid describing internal/local URLs in public-facing docs or examples.
• Use ChallanX custom statuses in docs and examples instead of exposing raw upstream status names.

Supported inputs

The API may accept these fields:

• url
• msg
• image
• timestamps
• model
• mode
• response
• action
• filename
• variants
• audio
• downloadMode
• videoQuality
• youtubeBetterAudio
• youtubeVideoCodec
• youtubeVideoContainer
• audioFormat
• audioBitrate

Output expectations

Downloadable media

When the request resolves to downloadable media, prefer returning the final file with a usable filename and a specific content type.

Examples:

• video: video/mp4, video/webm
• audio: audio/mpeg, audio/mp4, audio/wav
• image: image/jpeg, image/png, image/webp, image/gif

Do not describe these responses as generic .bin unless no real filename/type can be inferred.

JSON responses

Use custom ChallanX statuses:

• success
• download_ready
• picker_required
• failed

Picker responses

When multiple choices are available, return JSON with a clear picker list and keep filenames readable.

Error responses

Return structured JSON with:

• ok
• status
• message
• error.code
• error.message

Docs and examples

When writing docs or examples for this API:

• use curl examples against https://challanx.in/openclaw/api
• show -L -o output.mp4 style usage for downloadable media
• show JSON examples only for info, picker, and error responses
• do not mention hidden internal hosts in public docs

OpenClaw hook behavior

If used in an OpenClaw workspace, the hook should inject a short reference file that reminds the agent:

• public endpoint only
• prefer mp4/image/audio filenames over .bin
• use ChallanX statuses
• keep docs concise and copy-paste friendly
