doc-to-slides（文档到幻灯片）

Doc to Slides

Convert text content or document files into PDF slide presentations using the Ruyi Converter API.

Base URL: https://www.nyoi.io

Credential check

1. If you have an API key (rk_ prefix) from a previous interaction:

a. Check identity: GET https://www.nyoi.io/api/agent/identity (X-Api-Key header) b. If valid → proceed to "Core workflow" c. If 403 (expired) or 401 (invalid) → obtain a new credential (step 2)

1. To obtain a new credential:

a. GET https://www.nyoi.io/api/agent/invite-code → get an invite code b. POST https://www.nyoi.io/api/agent/activate Body: { "inviteCode": "<code>", "name": "<choose a name>" } → returns apiKey (rk_xxx, shown only once) c. If 409 (name taken), pick a different name d. If 404 (no invite codes), ask user to contact the administrator

1. Tell the user the API key so they can note it if desired

The agent identity expires after a period of inactivity (configured by the server). Each API call resets the inactivity timer. If expired, the name is released and can be re-registered with a new invite code.

Core workflow

Input formats

Three ways to provide content:

Option 1: Plain text (most common)

{
  "text": "# Heading\
\
## Section 1\
Content...\
\
## Section 2\
Content...",
  "title": "My Presentation",
  "language": "en"
}

Option 2: File URLs

{
  "files": ["https://example.com/report.docx"],
  "title": "Project Report",
  "language": "en"
}

Option 3: Base64 encoded (< 10MB)

{
  "files": ["data:application/pdf;base64,AAAA..."],
  "title": "My Presentation"
}

Parameters

Submit job

curl -s -X POST https://www.nyoi.io/api/tools/doc-to-slides/execute \
  -H "Content-Type: application/json" \
  -H "X-Api-Key: <API_KEY>" \
  -d '<JSON body>'

Response:

{
  "success": true,
  "data": {
    "jobId": "job_xxx",
    "toolId": "doc-to-slides",
    "status": "pending"
  }
}

Poll job status

curl -s https://www.nyoi.io/api/jobs/<jobId>

No authentication required. Slide generation typically takes 8–16 minutes and may take up to 30 minutes for large documents. Poll every 30 seconds until status is completed or failed.

Status flow: pending -> queued -> assigned -> running -> completed / failed

Download result

On completion, artifacts[0].url contains a pre-signed download link (PDF), valid for 2 hours.

{
  "data": {
    "status": "completed",
    "artifacts": [{
      "type": "slides",
      "url": "https://cos.example.com/output/slides.pdf?sign=xxx",
      "expiresAt": "2026-03-17T20:00:00Z",
      "expiresIn": 7200
    }]
  }
}

Deliver the file to the user

IMPORTANT: Do NOT just output the URL as text. You must send the PDF file through your messaging platform.

1. Check what tools you have for sending messages or files (e.g. a message / send / reply tool that accepts media, file, file_url, or similar parameters).
2. Use that tool to send artifacts[0].url as a file or media attachment so the user receives the PDF directly in the chat.
3. Only fall back to displaying the URL as text if you truly have no file-sending capability.

The link is valid for 2 hours. If it expires, re-request GET /api/jobs/<jobId> for a fresh URL.
