If multiple PDFs are processed, the output may include multiple PDFs and/or a ZIP for download. ### Credentials The API requires an API key used as a Bearer token: Authorization: Bearer How the user gets an API key: https://login.cross-service-solutions.com/register Or the user can provide an API key directly. Rule: never echo or log the API key. ### API endpoints Base URL: https://api.xss-cross-service-solutions.com/solutions/solutions Create watermark job: POST /api/61 multipart/form-data parameters: files — required — multiple PDF files (multiple_files) text — required — string (watermark text) Get result by ID: GET /api/ When done, the response contains: output.files[] with { name, path } where path is a downloadable URL (PDFs and/or ZIP). ### Required One or more PDF files (binary) Watermark text (text, string) API key (string) ### Optional None ### Output Return a structured result: job_id (number) status (string) outputs (array) containing { name, path } for each output file Convenience fields: download_url (string) if exactly one output exists download_urls (array of strings) for all outputs input_files (array of strings) watermark_text (string) — returned only if safe; do not return if user considers it sensitive Example output: { "job_id": 6101, "status": "done", "outputs": [ { "name": "watermarked.pdf", "path": "https://.../watermarked.pdf" } ], "download_url": "https://.../watermarked.pdf", "download_urls": ["https://.../watermarked.pdf"], "input_files": ["input.pdf"] } ## Trust - Source: tencent - Verification: Indexed source record - Publisher: CrossServiceSolutions - Version: 1.0.0 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-23T16:43:11.935Z - Expires at: 2026-04-30T16:43:11.935Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/add-watermark-to-pdf) - [Send to Agent page](https://openagent3.xyz/skills/add-watermark-to-pdf/agent) - [JSON manifest](https://openagent3.xyz/skills/add-watermark-to-pdf/agent.json) - [Markdown brief](https://openagent3.xyz/skills/add-watermark-to-pdf/agent.md) - [Download page](https://openagent3.xyz/downloads/add-watermark-to-pdf)
