bee-sdk

Official Python client and MCP server for Bee by HEOSSI - The Progressive Quantum-Native Intelligence Engine, a governed multimodal intelligence platform from HEOSSI.

SDK version: 1.0.14 - includes auditable BSIS domain-intelligence metadata, 14 governed MCP tools, readiness-aware MCP resources, typed per-call/BEE_MODEL selection across bee-cell through bee-swarm (access follows your key's plan), and stdio plus Streamable HTTP transports.

Includes a hosted Model Context Protocol server: pip install bee-sdk then run bee-mcp (stdio) to expose Bee's 14 tools to Claude Desktop, Cursor, VS Code, Zed, Windsurf, and other MCP clients:

• intelligence: bee_chat, bee_code, bee_security, bee_research
• trust and account: bee_verify_provenance, bee_usage
• knowledge: bee_documents_search, bee_documents_add
• memory: bee_memory_search, bee_memory_add
• Quantum Reasoning Lab: bee_quantum_reasoning_run, bee_quantum_reasoning_jobs, bee_quantum_reasoning_get, bee_quantum_reasoning_remove

It also serves bee://status, bee://domains, bee://documents, and bee://memory, plus the bee://documents/{source} resource template. Hosted writes and quantum execution remain tenant-scoped, explicitly described, and plan/policy gated. For a request/response remote endpoint, run bee-mcp --http PORT (localhost by default; put public deployments behind a trusted authenticated proxy). See bee.heossi.com/docs/mcp.

Status: functional sync + async client (stdlib + optional httpx). The SDK targets the Bee /chat/completions API contract on production via the public gateway https://api.bee.heossi.com/bee - this is the default and it is where API-key auth, plan / per-tier allowance enforcement and usage metering happen. Do not point BEE_API_URL at the raw Modal app URL: that bypasses billing and a bee_sk_ key is rejected there (the backend only trusts Supabase JWTs / the static BEE_API_KEYS env, not customer-issued keys). Override BEE_API_URL only for a self-hosted Bee Enclave or staging.

Install

Install from PyPI (canonical):

pip install bee-sdk          # sync client (stdlib only - zero deps)
pip install bee-sdk[async]   # async client (adds httpx)

Install + quickstart on the marketing site: bee.heossi.com/docs/sdks.

Quick start

from bee_sdk import Bee

bee = Bee()  # reads BEE_API_URL + BEE_API_KEY from env
print(bee.chat("Explain Shor's algorithm at NISQ depth", domain="quantum"))

Quantum work is submitted as a durable Quantum Reasoning Lab product job. For customer-local execution, use quantum_local_select; for direct customer-owned provider execution, use execute_byopa_direct.

For a durable, inspectable Lab run:

job = bee.quantum_reasoning_create(
    prompt="Compare two fault-tolerant designs.",
    model="bee-hive",
    product="simulation_cloud",
)
detail = bee.quantum_reasoning_wait(job["id"], timeout=900)
print(detail["status"], detail.get("candidates"), detail.get("inference_receipt_id"))

Pass a stable idempotency_key when your application may retry creation. Reusing that key with different input returns 409; reusing it with the same input returns the original job. quantum_reasoning_jobs(cursor=..., limit=..., status=..., model=...) supports cursor pagination. Automatic execution retry is deliberately unavailable; ambiguous work must be reconciled. quantum_reasoning_remove cancels an eligible queued job or erases the content of a terminal job, subject to workspace role controls.

Lab jobs are tenant-scoped, encrypted at rest, and retained for 90 days. Real-QPU execution is explicitly metered and any classical fallback is returned as such.

Durable Lab jobs require an explicit product: simulation_cloud or managed_qpu. local_simulator and byopa_direct run in the customer's own environment and never enter Bee's hosted queue. byopa_managed remains gated until its provider-specific managed adapter is activated.

Streaming

for chunk in bee.chat_stream("Write a Rust fibonacci function", domain="programming"):
    print(chunk, end="", flush=True)

Entitlement and capacity actions

Bee returns one versioned action contract for model access, domain tiers, allowances, credits, context recovery, documents, and rate limits. The SDK raises BeeActionRequiredError and preserves the complete decision:

from bee_sdk import Bee, BeeActionRequiredError

try:
    Bee().chat("Use Bee Hive.", model="bee-hive")
except BeeActionRequiredError as error:
    print(error.decision["reason"])
    print(error.decision["actions"])

Async

import asyncio
from bee_sdk import AsyncBee

async def main():
    async with AsyncBee() as client:
        text = await client.chat("Audit this contract for re-entrancy", domain="blockchain")
        print(text)

asyncio.run(main())

Multi-turn

from bee_sdk import Bee, ChatMessage

bee = Bee()
resp = bee.chat_messages(
    [
        ChatMessage(role="system", content="You are a senior security auditor."),
        ChatMessage(role="user", content="Review this nginx config for hardening gaps:\n\n..."),
    ],
    domain="cybersecurity",
    max_tokens=1024,
)
print(resp.content)
print(resp.usage, resp.interaction_id)

Feedback loop

resp = bee.chat_messages([...], domain="ai")
if user_likes_answer:
    bee.feedback(resp.interaction_id, rating="up")

Documents (RAG) & personal memory

Both are tenant-scoped to your API key's account. Documents need a rag-entitled plan; memory is a per-user opt-in (default-on).

# Documents - add to your knowledge base, then search it
bee.documents_add("Q3 revenue grew 14% QoQ to S$2.1M.", source="q3-report")
hits = bee.documents_search("how did revenue change in Q3?", k=3)

# Personal memory - remember a fact, recall it later
bee.memories_add("Prefers TypeScript over JavaScript.", kind="preference")
mem = bee.memories_search("language preference")  # {enabled, memories: [...]}

Domains

The domain= parameter selects which LoRA adapter Bee routes through. Tier-1 domains:

The gateway applies plan, model-tier, promotion, safety and availability gates to explicit domain requests. Omit domain to let Bee's governed classifier select the applicable available specialist. Domain adapters and model weights are served privately through the hosted gateway.

Environment variables

Errors

from bee_sdk import BeeAPIError, RateLimitError, BeeError

try:
    bee.chat("...", domain="quantum")
except RateLimitError as e:        # 429 after retries
    ...
except BeeAPIError as e:           # other HTTP errors
    print(e.status, e.body)
except BeeError:                   # network / timeout
    ...

The sync client retries 429/5xx with exponential backoff (max 4 attempts).

Versioning

bee-sdk follows the Bee API surface. Breaking API changes bump the minor version pre-1.0; the SDK is currently 1.0.14 and the API is v1.
