Liblib Comfy Fusion Generation

Generate images with LiblibAI ComfyUI App API (template-based workflow). Supports public image URL or local file.

For local files from Feishu, the recommended flow is:

1. upload the local file to R2 (S3-compatible) to get a public URL
2. use that public URL as the Liblib LoadImage input
3. return the Liblib result imageUrl as MEDIA:https://... so Feishu displays it directly

Prerequisites

Environment variables must be set:

• LIB_ACCESS_KEY — API access key
• LIB_SECRET_KEY — API secret key

Usage

Run the CLI at scripts/liblib_client.py:

# Public URL input
python3 scripts/liblib_client.py run --image-url "https://example.com/input.jpg"

# Local file (Feishu inbound attachment) → upload to R2 → use public URL
python3 scripts/liblib_client.py run --local-image "/path/to/input.png" --basename "product-fusion"

# Local file (advanced): embed as data URI (only if Liblib accepts it)
python3 scripts/liblib_client.py run --local-image "/path/to/input.png" --local-image-mode data-uri

# Parse URL from Feishu message text
python3 scripts/liblib_client.py run --feishu-text "请处理这个图 https://example.com/input.jpg"

# Submit only (no poll)
python3 scripts/liblib_client.py run --local-image "./input.jpg" --no-poll

# Query task status
python3 scripts/liblib_client.py status <generateUuid>

Output and Feishu 回传

• After a successful run (generateStatus=5), the script downloads images[].imageUrl into workspace/outputs/images/YYYY-MM-DD/<basename>.(png|jpg|...) (override with --output-dir).
• stdout prints a single line: MEDIA:./outputs/images/YYYY-MM-DD/<file> (relative to workspace/). Use this with OpenClaw Feishu channel so the image appears in the current chat without extra API calls.
• Full task JSON is printed to stderr for debugging.
• If MEDIA: is not supported in your channel, use feishu-uploader with --receive-id-type chat_id and the group chat_id, or --open-id for DM.

Parameters (run)

| Flag | Meaning | |------|--------| | --local-image | Local path; takes priority over URL. Default mode uploads to R2 and uses public URL. | | --local-image-mode | r2 (default) or data-uri. | | --image-url | Public URL the Liblib servers can fetch. | | --feishu-text / FEISHU_TEXT | Extract first http(s) URL from text. | | --output-dir | Default: <workspace>/outputs/images. | | --basename | Filename stem (default liblib-fusion). | | --no-download | Skip downloading result files. | | --no-print-media | Do not print MEDIA: line; stdout prints absolute path of first saved file instead. |

API Details

• Submit endpoint: POST /api/generate/comfyui/app
• Status endpoint: POST /api/generate/comfy/status
• Auth query params: AccessKey, Signature, Timestamp, SignatureNonce
• Signature algorithm:
  • content = uriPath & Timestamp & SignatureNonce
  • HMAC-SHA1(secretKey, content)
  • URL-safe Base64 without trailing =

Async Pattern

1. Submit task to get generateUuid
2. Poll status endpoint until generateStatus is 5 (success) or 6 (failed)
3. Read images[].imageUrl when successful

Notes

• URL input: must be publicly reachable by Liblib.
• Local input: default uses R2 upload to produce a public URL. Requires boto3.
• Returned image URLs are temporary (typically ~7 days).
• If API returns content review errors, try a different source image or URL.
