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:
- Build it yourself: Web scraping, search APIs, LLM integration, citation tracking. Weeks of work.
- Use a search API: Returns links, not answers. You still need to process and synthesize.
- 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:
- Streaming responses: Get results as they're generated instead of waiting for completion
- Custom source lists: Provide specific URLs to include in research
- Output formats: Markdown and HTML in addition to JSON
- Webhooks: Get notified when long-running deep research completes
- Source filtering: Include/exclude specific domains
Try It
The free tier includes 500 credits/month - enough for 500 shallow or ~166 medium research queries.
