Research Agent API · /research
Run a research agent with cited answers in a single API call.
Ask one question and get cited answers back, so your users can verify every claim without building or maintaining a research pipeline.

Synthesized Answer
Regional banks face intensifying capital requirements under the revised Basel III “endgame” rules1, alongside heightened scrutiny of commercial real-estate concentration following recent supervisory guidance2. Liquidity-coverage expectations have also tightened for institutions above the $100B threshold3 |

Trust
Give your users answers they can actually trust.
Answers include cited source URLs your users can verify, so you avoid confident-sounding hallucinations and "summarized the first result" outputs. They can inspect where conclusions came from.
Features
- ✓Citations + source URLs returned inline with every claim
- ✓Multi-source synthesis, not a summary of the first result
- ✓SSE streaming so users watch it work in real time, not a spinning wheel
import Tabstack from '@tabstack/sdk'
const client = new Tabstack()

query: 'What are the key regulatory risks facing regional banks in 2025?',

for await (const event of stream) {

console.log(result.report) // synthesized answer

}

// source selection logic → replaced

// After: one call

try {
for await (const event of stream) {
if (event.event === 'complete') { console.log(event.data.report) }

}
} catch (err) { console.error(err) }Pipeline
Ship a research tool without building the research pipeline.
Give it a question and it finds sources, reads them, synthesizes an answer, and returns citations. Source selection, synthesis prompting, citation formatting, and streaming are all handled inside a single call.
Features
- ✓/research delivers the entire research pipeline in one endpoint
- ✓Source selection, synthesis, citation handling all inside the call
- ✓No orchestration code in your codebase
Live web
Answer from the live web, not a stale index.
Most research APIs answer from pre-indexed data. /research fetches and reads live pages at request time, so your users get current sources, not yesterday's crawl.
Features
- ✓Live retrieval at request time from the open web
- ✓Better coverage for niche and newly published sources
- ✓Choose mode: "fast" for speed or mode: "balanced" for deeper synthesis
Pre-indexed API
- ×Answers from a stale crawled corpus
- ×Misses niche & just-published sources
- ×Locked to a pre-defined topic set
Yesterday's Index
/research
live- ✓Fresh data from the live web
- ✓Niche sources & content published today
- ✓Works on any question you send
Who builds on this
Teams that rely on cited, sourced answers.
Legal tech
Citation trail is non-negotiable. Wrong answers are a liability.
Financial services
Every data point needs a traceable source.
Sales intelligence
Reps trust a brief when they can see where it came from.
Competitive intelligence
Sourced change summaries, not raw diffs.
From the developers
“I was burning thousands of credits on Tavily for results that still required cleanup. Tabstack hands back cited answers. I stopped thinking about the retrieval layer entirely.”

Privacy & trust
Privacy, Transparency, and Control
When you build on /research, your users' questions and the data behind every answer stay yours. Tabstack is a Mozilla-backed platform, and we handle live-web research responsibly, so you can ship features your users actually trust.
Private by default. Queries and retrieved pages are ephemeral, used to build your answer, then purged. Never stored, never sold, never used to train models.
Verifiable by design. Every answer returns source URLs and inline citations, so you and your users can confirm exactly where each claim came from.
Yours to control. You set the mode, scope, and depth of every call. No retained corpus, no lock-in, just clean, cited data you own.
See exactly how we source and handle data in the documentation.
