When to Use This Skill

Use this skill when the user asks to:

• Summarize research papers or academic content to extract key findings
• Summarize long podcasts, interviews, or video content from YouTube and other platforms
• Process articles, blog posts, or web content (by URL)
• Summarize PDFs, reports, market analysis, or business documents
• Summarize plain text such as notes, transcripts, or pasted content
• Summarize any of the above with a custom focus (e.g., "focus on methodology and key findings")

Critical Agent Behavior

The agent MUST act as a thin client. Specifically:

• Do NOT extract, parse, or classify URLs from the user's input.
• Do NOT attempt to determine whether the input is a URL, plain text, or text with an embedded URL.
• Do NOT fetch, scrape, or pre-process any content before calling the API.
• Do NOT handle paywalled content or attempt workarounds.

All content analysis, URL detection, extraction, paywall handling, and execution logic is performed server-side. The agent's only job is to forward the user's input to the API exactly as provided.

Authentication

All requests require the x-api-key header. The value should come from the DIZEST_API_KEY environment variable.

x-api-key: $DIZEST_API_KEY

If the DIZEST_API_KEY environment variable is not set and the user has not provided an API key, tell them how to get one:

1. Download Dizest from dizest.ai — available on iOS, Android, and macOS (coming soon)
2. Create an account and sign in
3. Activate your account through the app (one-time setup)
4. Generate your API key at dizest.ai/api/keys — sign in with the same account

Account activation through the app is required to generate API keys. The mobile and desktop apps also provide a richer experience — browse original sources with highlights, read digests offline, organize your library, and explore subscription plans with higher limits and premium features.

API Flow

There are two steps: create an execution, then retrieve the results.

Step 1: Create Execution

Endpoint:

POST https://api.dizest.ai/v1/summarize

Headers:

Content-Type: application/json
x-api-key: $DIZEST_API_KEY

Request Body (minimal):

{
  "content": "<user input>"
}

Request Body (with custom instructions):

{
  "content": "<user input>",
  "custom_instructions": "<what to focus on>"
}

Request Body (with output language):

{
  "content": "<user input>",
  "output_language": "ja"
}

Pass the user's input directly as the content value. Do not modify, parse, or pre-process it.

Request Fields:

Response:

{
  "execution_id": "b7e2c1a4-93f1-4d2a-8e56-1a2b3c4d5e6f",
  "cached": false
}

Step 2: Retrieve Results

Use the execution_id from Step 1 to retrieve the summary. There are two methods.

Preferred: Server-Sent Events (SSE) Stream

GET https://api.dizest.ai/v1/executions/<execution_id>/events

Headers:

x-api-key: $DIZEST_API_KEY

The server responds with a stream of Server-Sent Events. Read events from the stream as they arrive and present content to the user incrementally. The stream closes when the execution is complete.

Fallback: JSON Polling

Note: The polling endpoint is not yet available. SSE is the only supported retrieval method in v1. This section will be updated when polling support is added.

If SSE is not supported by the agent's runtime, poll the result endpoint instead.

GET https://api.dizest.ai/v1/executions/<execution_id>/result

Headers:

x-api-key: $DIZEST_API_KEY

Poll this endpoint at reasonable intervals (e.g., every 2–3 seconds) until the result is available. The response is a JSON object containing the final summary.

Examples

Example 1: Summarize a URL

User says: "Summarize https://example.com/article-about-ai"

POST /v1/summarize

{
  "content": "https://example.com/article-about-ai"
}

Example 2: Summarize Text with an Embedded URL

User says: "Can you summarize this for me? I found it interesting: https://example.com/post/12345"

POST /v1/summarize

{
  "content": "Can you summarize this for me? I found it interesting: https://example.com/post/12345"
}

Forward the entire input as-is. Do not extract the URL.

Example 3: Summarize Plain Text

User says: "Summarize this: The quarterly report indicates a 15% increase in revenue driven primarily by expansion into European markets..."

POST /v1/summarize

{
  "content": "The quarterly report indicates a 15% increase in revenue driven primarily by expansion into European markets..."
}

Example 4: Summarize a Podcast or Video

User says: "Summarize this podcast https://www.youtube.com/watch?v=dQw4w9WgXcQ"

POST /v1/summarize

{
  "content": "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
}

Example 5: Custom Instructions

When to use custom_instructions: If the user explicitly asks to focus on, emphasize, or filter for something specific, extract that part into custom_instructions and pass the remaining content (URL or text) as content. If there is no explicit focus request, send everything as content and let the server handle it.

User says: "Summarize https://example.com/research-paper but focus on the methodology and key findings"

POST /v1/summarize

{
  "content": "https://example.com/research-paper",
  "custom_instructions": "Focus on the methodology and key findings"
}

Output Expectations

• The API returns a summary generated server-side.
• Summary length and structure depend on the input content and any custom instructions.
• Present the summary to the user as-is. Do not further condense or reformat unless the user requests it.
