dominus-sdk-python 4.0.0

Python SDK for the Dominus gateway-first platform

Dominus SDK for Python

Async Python SDK for the Dominus gateway-first service plane.

What This Repo Ships

• Python 3.9+ asyncio client for Dominus services
• Namespace-first API with a small root shortcut surface
• Gateway-scoped client mode for MCP and other user-JWT sessions
• Local helpers for JWT verification, trace propagation, retries, and console capture
• Current package version: 3.0.5

Install

pip install dominus-sdk-python
pip install dominus-sdk-python[jwt]
pip install dominus-sdk-python[dev]

Quick Start

import os
from dominus import dominus

os.environ["DOMINUS_TOKEN"] = "your-psk-token"

value = await dominus.secrets.get("DB_URL")
users = await dominus.db.query("users", filters={"status": "active"})
await dominus.redis.set("session:123", {"user": "john"}, ttl=3600)

run = await dominus.workflow.ensure(
    "wf://carebridge/report-cycle",
    subject="PCM47474562",
    company="summit-radiology",
)

timeline = await dominus.authority.get_run_timeline(
    run["run_id"],
    since="2026-04-11T08:33:00Z",
    until="2026-04-11T09:33:00Z",
)

Session-Scoped Clients

Production MCP and other user-session callers should instantiate Dominus with gateway scope context instead of relying on the service-token flow:

from dominus import Dominus

client = Dominus(
    gateway_user_token=user_jwt,
    gateway_org_id=org_id,
    gateway_app_slug=app_slug,
    gateway_env=env,
)

me = await client.portal.me(user_token=user_jwt)

When these fields are set, _request(..., use_gateway=True) forwards the user JWT and selected scope headers directly through Gateway.

Transport Model

• Default HTTP targets are the production gateway (https://gateway.getdominus.app); they do not change based on your app’s git branch or PyPI package variant. Set DOMINUS_GATEWAY_URL (or DOMINUS_BASE_URL / DOMINUS_JWT_URL) only for local or custom routing.
• DOMINUS_TOKEN is exchanged for a JWT through POST /jwt/mint
• Service JWTs are cached for 14 minutes with a 60-second refresh window
• Auth-required worker routes still send base64-encoded JSON bodies as text/plain
• Responses may arrive as legacy base64 JSON or raw JSON; the SDK accepts both
• Gateway-routed namespaces translate /api/* to /svc/*
• SSE and binary helpers bypass JSON decoding where appropriate

Namespace Inventory

Namespace	Backing surface	Purpose
secrets	Warden	Secrets CRUD
db	DB Worker	Database CRUD and metadata
secure	DB Worker	Audit-logged data access
redis	Redis Worker	Cache, hashes, TTL, counters
files	B2 / storage surfaces	File upload, fetch, listing, folders
auth	Guardian + JWT routes	RBAC, tenants, pages, secure tables, JWKS
ddl	Smith / DDL worker	Schema, migrations, provisioning
logs	Logs Worker	Structured logs and tail/query helpers
portal	Portal Worker	Login, sessions, profile, preferences, nav
courier	Courier Worker	Template email delivery
health	Gateway	Health and ping helpers
admin	Admin Worker	Admin category reseed/reset
ai	Agent Runtime	Agent, completion, RAG, artifacts, results, raw orchestration
workflow	Workflow Manager + Authority	Saved workflow CRUD and canonical run lifecycle
artifacts	Artifact Worker	Addressed V2 artifacts, bookmarks, watches
jobs	Job Worker	Enqueue, poll, dead-letter management
processor	Processor	Batch and single-job processing
sync	Sync Worker	KV synchronization
authority	Dominus Authority	Runs, companies, deploys, managed clients, context
deployer	Deployer	Thin operator control-plane request surface
warden	Warden	Thin operator control-plane request surface
fastapi	Local decorators	@jwt, @psk, @scopes(...)

Root Shortcuts

The root Dominus object still exposes a small compatibility surface for common operations:

• get, upsert
• list_tables, query_table, insert_row, update_rows, delete_rows
• add_table, add_column, delete_table, delete_column
• await dominus("secrets.get", key="DB_URL")

New code should prefer namespace APIs.
