Launching the Aegis Research API: AI-Powered Research as a Service

January 6, 2026

Today we're launching the Aegis Research API - a REST API that provides AI-powered research capabilities on any topic. Send a query, get back comprehensive, cited research in seconds.

The Problem

Developers building AI applications often need to incorporate research capabilities - answering questions, gathering information, synthesizing multiple sources. The options today are:

  1. Build it yourself: Web scraping, search APIs, LLM integration, citation tracking. Weeks of work.
  2. Use a search API: Returns links, not answers. You still need to process and synthesize.
  3. Direct LLM queries: No real-time data, hallucination risks, no source citations.

We wanted something different: Send a question, get a researched answer with sources.

The Solution

The Research API handles the entire research pipeline:

Topic → Web Search → Source Retrieval → AI Synthesis → Cited Response

A single API call:

curl -X POST https://aegisagent.ai/api/v1/research \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your_api_key" \
  -d '{"topic": "What are best practices for API rate limiting?"}'

Returns structured research:

{
  "summary": "API rate limiting protects services from abuse while ensuring fair resource allocation...",
  "key_findings": [
    "Token bucket algorithms provide flexible rate limiting",
    "Response headers should communicate limits clearly",
    "Consider tiered limits based on user plans"
  ],
  "detailed_analysis": "Rate limiting is essential for...",
  "sources": [
    {
      "url": "https://example.com/article",
      "title": "API Rate Limiting Guide",
      "relevance_score": 0.95
    }
  ],
  "credits_used": 1
}

Why Claude Agent SDK + Haiku?

We use Claude Agent SDK with Haiku 4.5 for the synthesis step. Why this combination?

Speed: Haiku is optimized for fast inference. Research queries complete in 10-30 seconds depending on depth.

Cost efficiency: Haiku is approximately 1/3 the cost of Sonnet while delivering excellent synthesis quality for research tasks.

Agent capabilities: The Agent SDK provides tool use, context management, and structured output handling out of the box.

Subscription leverage: Using Claude Max subscription via OAuth token means predictable costs regardless of usage spikes.

# Simplified synthesis step
from claude_agent_sdk import query, ClaudeAgentOptions

async for message in query(
    prompt=f"""Synthesize research on: {topic}

    Sources:
    {formatted_sources}

    Provide: summary, key_findings, detailed_analysis""",
    options=ClaudeAgentOptions(model="haiku")
):
    # Process streaming response
    result.append(message)

Semantic Caching

Identical queries within 24 hours return cached results at no credit cost. The cache uses semantic similarity, so "What is WebAssembly?" and "Explain WebAssembly" may hit the same cache entry.

# Cache key generation (simplified)
cache_key = f"{topic.lower().strip()}:{depth}"
cached = await semantic_cache.get(cache_key)
if cached:
    return cached  # No credits charged

Depth Levels

Research depth affects source count, processing time, and credit cost:

Depth Sources Time Credits Best For
shallow 3 ~15s 1 Quick facts, verification
medium 5-7 ~30s 3 General research
deep 10+ ~2min 10 Comprehensive investigation

Most use cases work well with shallow or medium. Reserve deep for topics requiring extensive coverage.

Credit-Based Pricing

We chose credits over per-request pricing for flexibility:

Tier Credits/Month Rate Limit Price
Free 500 10/min $0
Starter 500 20/min $9/mo
Pro 5,000 60/min $49/mo
Enterprise Unlimited 200/min Contact

Why credits? A shallow research (1 credit) shouldn't cost the same as a deep research (10 credits). Credits let you optimize for your use case.

Integration Examples

Python SDK Pattern

import requests
from functools import lru_cache

class ResearchClient:
    def __init__(self, api_key: str):
        self.api_key = api_key
        self.base_url = "https://aegisagent.ai/api/v1/research"

    def research(self, topic: str, depth: str = "medium") -> dict:
        response = requests.post(
            self.base_url,
            headers={"X-API-Key": self.api_key},
            json={"topic": topic, "depth": depth}
        )
        response.raise_for_status()
        return response.json()

    def get_credits(self) -> dict:
        response = requests.get(
            f"{self.base_url}/credits",
            headers={"X-API-Key": self.api_key}
        )
        return response.json()

# Usage
client = ResearchClient("your_api_key")
result = client.research("What is WebAssembly?", depth="shallow")
print(result["summary"])

Async JavaScript

async function research(topic, depth = "medium") {
  const response = await fetch("https://aegisagent.ai/api/v1/research", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "X-API-Key": process.env.AEGIS_API_KEY
    },
    body: JSON.stringify({ topic, depth })
  });

  if (!response.ok) {
    const error = await response.json();
    throw new Error(error.detail?.error || "Research failed");
  }

  return response.json();
}

// With retry logic
async function researchWithRetry(topic, retries = 3) {
  for (let i = 0; i < retries; i++) {
    try {
      return await research(topic);
    } catch (e) {
      if (e.message.includes("rate limit") && i < retries - 1) {
        await new Promise(r => setTimeout(r, 60000)); // Wait 1 min
        continue;
      }
      throw e;
    }
  }
}

LangChain Tool

from langchain.tools import BaseTool
from pydantic import BaseModel, Field

class ResearchInput(BaseModel):
    topic: str = Field(description="The topic to research")
    depth: str = Field(default="medium", description="shallow, medium, or deep")

class ResearchTool(BaseTool):
    name = "research"
    description = "Research any topic and get cited information"
    args_schema = ResearchInput

    def _run(self, topic: str, depth: str = "medium") -> str:
        client = ResearchClient(os.environ["AEGIS_API_KEY"])
        result = client.research(topic, depth)
        return f"{result['summary']}\n\nSources: {len(result['sources'])}"

What's Next

This is v1. Planned improvements:

  1. Streaming responses: Get results as they're generated instead of waiting for completion
  2. Custom source lists: Provide specific URLs to include in research
  3. Output formats: Markdown and HTML in addition to JSON
  4. Webhooks: Get notified when long-running deep research completes
  5. Source filtering: Include/exclude specific domains

Try It

The free tier includes 500 credits/month - enough for 500 shallow or ~166 medium research queries.
