Deep Research with Caesar.org

Deep research using the Caesar API — run queries, follow up with chat, brainstorm, and manage collections.

Caesar Research

CLI for Caesar deep research. Runs multi-source research jobs with citations, follow-up chat, and brainstorming.

Setup

bash

go install github.com/alexrudloff/caesar-cli@latest
export CAESAR_API_KEY=your_key_here

Research

Run a query (waits for completion by default, prints events as they happen):

bash

caesar research create "What are the latest advances in mRNA vaccines?"

Returns JSON with content (synthesized answer with [n] citations) and a results array of sources.

Fire-and-forget:

bash

caesar research create "query" --no-wait
# Returns: { "id": "uuid", "status": "queued" }

Then check on it:

bash

caesar research get <job-id>
caesar research watch <job-id>
caesar research events <job-id>

Research Options

Flag	Description
--no-wait	Return immediately with job ID
--model <name>	gpt-5.2, gemini-3-pro, gemini-3-flash, claude-opus-4.5
--loops N	Max reasoning loops (default 1, higher = deeper research)
--reasoning	Enable advanced reasoning mode
--auto	Let Caesar auto-configure based on query
--exclude-social	Skip social media sources
--exclude-domain x.com	Exclude specific domains (repeatable)
--system-prompt "..."	Custom synthesis prompt
--brainstorm <id>	Use a brainstorm session for context

Status Lifecycle

queued → searching → summarizing → analyzing → researching → completed or failed

Chat (Follow-Up Questions)

Ask follow-up questions about a completed research job:

bash

caesar chat send <job-id> "How does this compare to traditional vaccines?"

Waits for the response by default. The answer includes inline [n] citations referencing the original research sources.

bash

caesar chat send <job-id> "question" --wait=false
caesar chat history <job-id>

Brainstorm

Get clarifying questions before research to improve results:

bash

caesar brainstorm "How does CRISPR gene editing work?"
# Prints questions with multiple-choice options and a session ID

Then use the session ID:

bash

caesar research create --brainstorm <session-id> "How does CRISPR gene editing work?"

Collections

Group files for research context:

bash

caesar collections create "Dataset Name" --description "Optional description"

Tips

• For broad topics, use --auto to let Caesar pick optimal settings.
• Use --loops 3 or higher for complex multi-faceted questions.
• Use --reasoning for questions requiring deep analysis.
• Pipe output through jq to extract specific fields: caesar research get <id> | jq '.content'
• Chain brainstorm → research for best results on ambiguous queries.
