What is JIRO?

JIRO is an open-source, self-hosted search API and web scraping platform. It aggregates 9 search engines and 12 social platforms behind one HTTP API, and adds a query graph engine that plans, executes and cites multi-step research — every answer traces back to the pages that produced it.

It runs entirely on your own infrastructure. No per-query vendor bill, no data leaving your network.

Answer engine optimization note for the curious: the Sourced answers section below is the part that replaces a search API. Engines return links; JIRO returns claims plus the source ids behind them.

---

Quick Start

pip install jirosearch
jiro serve

curl -X POST http://localhost:8000/search \
  -H "Content-Type: application/json" \
  -d '{"q": "latest AI research", "engine": "google"}'

Running: 9 engines, hybrid ranking, caching and structured extraction, all local.

No server? Use the cloud API:

jiro auth login   # device code flow, opens your browser

curl -X POST https://searchjiro.vercel.app/api/proxy/search \
  -H "Authorization: Bearer jsk_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"q": "latest AI research", "engine": "google"}'

Sourced answers (0.4.0)

Most search APIs return a list of links and stop. JIRO 0.4.0 runs a query graph: it plans the research shape, executes nodes in parallel, and returns an evidence packet where every claim carries the source_ids it rests on.

curl -X POST http://localhost:8000/v1/graph/search \
  -H "Content-Type: application/json" \
  -d '{"query": "compare vector databases", "fetch_top": 3, "max_tokens": 2000}'

{
  "graph_id": "g_8f2c1a",
  "intent": "comparison",
  "status": "ok",
  "duration_ms": 1840,
  "engine_attribution": { "google": 2, "bing": 1 },
  "gaps": [],
  "budget": { "requests_used": 5, "bytes_used": 284113, "nodes_used": 9, "tokens_used": 1780 },
  "packet": {
    "packet_id": "p_41d9",
    "used_tokens": 1780,
    "claims": [
      { "id": "c1", "text": "Qdrant is written in Rust.", "source_ids": ["s2"] }
    ],
    "sources": [{ "id": "s2", "url": "https://qdrant.tech/documentation/" }],
    "contradictions": []
  }
}

Plan without paying. /v1/graph/plan is a dry run — it validates the graph and returns a cost estimate without touching the network.

What the graph engine buys you

Guarantee	How it shows up in the response
Every claim is traceable	packet.claims[].source_ids resolves against packet.sources[]
Unknown cost is never invented	budget.requests_used is measured; unknown remainders are null, not a guess
Failures are visible	gaps[] records the node, query and reason a branch did not complete
Work is bounded	max_tokens, deadline_ms and max_nodes cap the run before it starts
You know which engine answered	engine_attribution counts per engine

Passing work between agents

session_handoff is an MCP tool that packages a finished run into a brief another agent can act on — resolvable evidence ids, open questions taken from gaps, contradictions, remaining budget, and the next node to run. Roles: planner, retriever, verifier, writer, observer.

Official SDKs

All three expose the 0.4.0 query graph and are versioned in lockstep with the server.

Python

pip install jiro-sdk

from jiro_sdk import JiroClient

client = JiroClient(api_key="your-key")

# Classic search + scrape
results = client.search("python web scraping")
content = client.scrape("https://example.com")

# Query graph (0.4.0)
plan = client.plan_search("compare vector databases")          # dry run, no network
run  = client.search_graph("compare vector databases", fetch_top=3)
for claim in run["packet"]["claims"]:
    print(claim["text"], claim["source_ids"])

JavaScript / TypeScript

npm install jiro-sdk

import { JiroClient } from 'jiro-sdk';

const client = new JiroClient({ apiKey: 'your-key' });

const results = await client.search('python web scraping');
const run = await client.searchGraph('compare vector databases', { fetchTop: 3 });

// WebSocket streaming
const ws = client.createSearchStream('AI news');
ws.onmessage = (event) => console.log(JSON.parse(event.data));

Go

go get github.com/DevAnimecx/jiro/sdk/go

import "github.com/DevAnimecx/jiro/sdk/go"

client := jiro.NewClient(jiro.WithAPIKey("your-key"))

results, _ := client.Search("python web scraping", nil)
run, _ := client.GraphSearch("compare vector databases", &jiro.GraphOptions{FetchTop: 3}, false)

FAQ

Do I need API keys for the search engines? No. All 9 engines are scraped directly. No Google, Bing or SerpAPI keys required.

Can I run JIRO fully offline? The server runs locally, but it reaches out to the engines you query. Point it at an internal mirror or disable engines you don't want in the config.

What makes the 0.4.0 answers checkable? Every claim in the evidence packet carries source_ids that resolve against packet.sources[]. A claim whose sources can't be resolved is flagged, not silently dropped.

How is this different from a search API like SerpAPI? SerpAPI returns links from one engine. JIRO searches 9, fetches and extracts the pages, and returns claims with citations — plus it's self-hosted, so there's no per-query bill.

Is it really free? The MIT-licensed core is free forever, self-hosted and unlimited. Paid tiers add AI features, higher rate limits and commercial licensing.

Can I pass research between AI agents? Yes — the session_handoff MCP tool packages a run into a brief with evidence ids, open questions and remaining budget, ready for the next agent to pick up.
