Python SDK for BrowseAI Dev — reliable research infrastructure for AI agents

browseai

Reliable research infrastructure for AI agents. Python SDK for BrowseAI Dev — the research layer for LangChain, CrewAI, and custom agent pipelines.

Install

pip install browseai

Quick Start

from browseai import BrowseAI

client = BrowseAI(api_key="bai_xxx")

# Research with citations
result = client.ask("What is quantum computing?")
print(result.answer)
print(f"Confidence: {result.confidence:.0%}")
for source in result.sources:
    print(f"  - {source.title}: {source.url}")

# Thorough mode — auto-retries if confidence < 60%
thorough = client.ask("What is quantum computing?", depth="thorough")

# Deep mode — multi-step reasoning with gap analysis (requires BAI key)
deep = client.ask("Compare CRISPR approaches", depth="deep")
for step in deep.reasoning_steps or []:
    print(f"  Step {step.step}: {step.query} ({step.confidence:.0%})")

# Web search
results = client.search("latest AI news", limit=5)

# Page extraction
page = client.open("https://example.com")

# Structured extraction from a URL
extract = client.extract("https://example.com", query="pricing info")

# Compare raw LLM vs evidence-backed
compare = client.compare("Is Python faster than Rust?")

# Submit feedback to improve accuracy
client.feedback(result_id=result.share_id, rating="good")

Async

from browseai import AsyncBrowseAI

async with AsyncBrowseAI(api_key="bai_xxx") as client:
    result = await client.ask("What is quantum computing?")
    # Thorough mode works with async too
    thorough = await client.ask("What is quantum computing?", depth="thorough")
    # Deep mode — multi-step agentic reasoning (requires BAI key)
    deep = await client.ask("Complex research question", depth="deep")

Streaming (REST API)

For real-time progress events, use the streaming endpoint directly:

import httpx

with httpx.stream("POST", "https://browseai.dev/api/browse/answer/stream",
    json={"query": "What is quantum computing?"},
    headers={"X-Tavily-Key": "tvly-xxx", "X-OpenRouter-Key": "sk-or-xxx"}
) as response:
    for line in response.iter_lines():
        if line.startswith("data: "):
            print(line[6:])

Events: trace (progress), sources (discovered early), token (streamed answer text), result (final answer), done.

Research Memory (Sessions)

Persistent research sessions that accumulate knowledge across multiple queries. Later queries recall prior knowledge — faster, cheaper, more coherent.

Sessions require a BrowseAI Dev API key (api_key="bai_xxx") for identity and ownership. BYOK clients (tavily_key/openrouter_key only) can use search/answer but cannot create or access sessions. Get a free API key at browseai.dev/dashboard.

from browseai import BrowseAI

client = BrowseAI(api_key="bai_xxx")

# Create a session
session = client.session("wasm-research")

# Each query builds on previous knowledge
r1 = session.ask("What is WebAssembly?")
r2 = session.ask("How does WASM compare to JavaScript performance?")
# ^ r2 recalls WASM knowledge from r1, only searches for JS perf

# Query accumulated knowledge without new searches
recalled = session.recall("WASM")
for entry in recalled.entries:
    print(f"  {entry.claim} (from: {entry.origin_query})")

# Export all knowledge
knowledge = session.knowledge()

# Delete a session
session.delete()

# List all your sessions
sessions = client.list_sessions()

# Resume an existing session by ID
session = client.get_session("session-id-here")

# Share with other agents
share = session.share()
print(share.url)  # https://browseai.dev/session/share/abc123def456

# Another agent forks and continues the research
forked = client.fork_session(share.share_id)

Async sessions work the same way:

async with AsyncBrowseAI(api_key="bai_xxx") as client:
    session = await client.session("my-project")
    r1 = await session.ask("What is WASM?")
    r2 = await session.ask("WASM vs JS?")

    # Share and fork work async too
    share = await session.share()
    forked = await client.fork_session(share.share_id)

Premium Features (with API Key)

Users with a BrowseAI Dev API key (bai_xxx) get enhanced verification:

• Neural cross-encoder re-ranking — search results re-scored by semantic query-document relevance
• NLI semantic reranking — evidence matched by meaning, not just keywords
• Multi-provider search — parallel search across multiple sources for broader coverage
• Multi-pass consistency — claims cross-checked across independent extraction passes (in thorough mode)
• Deep reasoning mode — multi-step agentic research with iterative gap analysis (up to 4 steps)
• Token streaming — per-token answer delivery via SSE for real-time UI
• Research Sessions — persistent memory across queries

Free BAI key users get a generous daily quota (50 premium queries/day). When exceeded, queries gracefully fall back to BM25 keyword verification — still works, just basic matching. Quota resets every 24 hours. Check client.last_quota after any API call for current usage.

No account needed — BYOK works out of the box with no signup, no limits, and BM25 keyword verification. Sign in at browseai.dev for a free BAI key to unlock premium features.

BYOK (Bring Your Own Keys)

No signup required — just pass your own keys:

client = BrowseAI(tavily_key="tvly-xxx", openrouter_key="sk-or-xxx")
