copass-core 0.3.0

Core client SDK for the Copass platform (Python mirror of @copass/core)

copass-core

Core client SDK for the Copass platform. Python mirror of @copass/core — shared foundation for every Python Copass adapter.

Install

pip install copass-core

Requires httpx>=0.27. Python ≥ 3.10.

Quickstart

import asyncio
from copass_core import CopassClient, ApiKeyAuth

async def main():
    client = CopassClient(auth=ApiKeyAuth(key="olk_..."))

    # Retrieval
    menu = await client.retrieval.discover(
        sandbox_id="sb_...",
        query="How does auth work?",
    )
    print(menu["items"])

    # Context for agent
    context = await client.context.for_agent(
        sandbox_id="sb_...",
        tier="adaptive",
        query="auth flow",
    )
    print(context)

asyncio.run(main())

Auth options

from copass_core import CopassClient, ApiKeyAuth, BearerAuth, ProviderAuth

# Long-lived API key (olk_ prefix)
CopassClient(auth=ApiKeyAuth(key="olk_..."))

# Raw Bearer JWT (caller owns refresh)
CopassClient(auth=BearerAuth(token="eyJ..."))

# Custom AuthProvider implementation
class MyProvider:
    async def get_session(self):
        from copass_core import SessionContext
        return SessionContext(access_token=await _mint_token())

CopassClient(auth=ProviderAuth(provider=MyProvider()))

Available resources

Full resource surface matching @copass/core:

client = CopassClient(auth=ApiKeyAuth(key="olk_..."))

# Narrow retrieval tools
await client.retrieval.discover(sandbox_id, query="...")
await client.retrieval.interpret(sandbox_id, query="...", items=[...])
await client.retrieval.search(sandbox_id, query="...")
await client.context.for_agent(sandbox_id="...", tier="adaptive")

# Storage layer
await client.sandboxes.create(name="...", owner_id="...")
await client.sources.register(sandbox_id, provider="custom", name="...")
await client.ingest.text_in_sandbox(sandbox_id, text="...")
await client.projects.create(sandbox_id, name="...")
await client.vault.store(sandbox_id, "key/path", b"bytes")

# Knowledge graph
await client.entities.search(sandbox_id, q="auth")
await client.matrix.query(query="...")

# Account
await client.users.get_profile()
await client.api_keys.create(name="ci")
await client.usage.get_balance()

# Higher-order — ephemeral data source wrapping agent conversation
window = await client.context_window.create(sandbox_id=sandbox_id)
await window.add_turn(ChatMessage(role="user", content="..."))
# Pass directly to retrieval for window-aware calls:
await client.retrieval.search(sandbox_id, query="...", window=window)

v0.2 scope

Shipped in v0.2:

• Full resource surface (12 resource classes, all public paths).
• ContextWindow + ContextWindowResource.
• BaseDataSource + ensure_data_source for custom driver subclasses.
• HttpClient raw-body / raw-response support (enables vault blob I/O).

Deferred to v0.3:

• Crypto primitives (HKDF, AES-GCM, session tokens, DEK).
• Supabase OTP auth provider (requires crypto).
• BearerAuth(encryption_key=...) currently stores the key but doesn't derive a session token — works when the server doesn't demand one.

Open a PR with a scoped addition if you need those sooner.
