Python SDK · v1 stable

Typed. Async-first. Built for production.

One typed Python client for every product on the platform. Pydantic v2 throughout, idempotency keys handled for you, evidence verification a single call — with a matching CLI for the moments code is overkill.

◆ Six guarantees

Six things every SDK call guarantees.

The same guarantees whether you're uploading a CSV or driving the agentic workflow. No surprises, no hidden retries, no untyped JSON blobs.

rule · 01

100% typed

Pydantic v2 models for every request and response. mypy-strict on the client. Your IDE knows every field.

rule · 02

Async-first

Every method is awaitable. Sync wrappers exist where you need them, but async is the primary surface.

rule · 03

Idempotency built in

Idempotent retries on POSTs out of the box; the SDK manages your Idempotency-Key for you.

rule · 04

Streaming evidence

First-class helpers to subscribe to evidence-chain events and verify the BLAKE3 hash chain offline.

rule · 05

Contract-test runner

Drop the contract runner into your CI to lock the SDK↔API contract — caught upstream, not in prod.

rule · 06

Matching CLI

Every SDK call has a rady CLI sibling for shell pipelines, one-off ops, and the interactive REPL. See /developer/cli.

◆ Quickstart

From pip install to a signed bundle in 30 seconds.

shell · zsh

pip install radmah-sdk radmah-cli
rady auth login                          # OS-keyring credential, one-time

# Reviewed Fabricate dataset via the SDK
python3 -c "
from radmah_sdk import RadMahClient
c = RadMahClient(api_key='sl_live_...')
pv = c.create_fabricate_preview(
    '200 SaaS accounts MRR 50-5000',
    requested_records=200, seed=42,
)
c.wait_fabricate_preview(pv['preview_id'])
ap = c.approve_fabricate_preview(pv['preview_id'])
job = c.get_job(ap['job_id'])
print(job.wait().to_dataframe().head())
"

# Or scripted via the CLI
PV=$(rady fabricate preview "200 SaaS accounts MRR 50-5000" -n 200 -q)
rady fabricate approve $PV -n 200 -o mock.csv

# Verify any evidence bundle offline
rady evidence download <job-id> -o bundle.json
rady evidence verify bundle.json

◆ Reference notebooks

Six reference notebooks. One per product surface.

01-fabricate.ipynb

Preview, refine, and approve a sealed dataset from a prompt.

02-synthesize.ipynb

Train it on a CSV upload, fetch the bundle.

03-agent.ipynb

Drive the Agentic Data Scientist end-to-end.

04-scada.ipynb

Spin up a Virtual SCADA run, capture telemetry.

05-evidence.ipynb

Verify any bundle, walk the BLAKE3 hash chain offline.

06-webhooks.ipynb

Receive signed events, validate signatures.

◆ Support

Language support, version policy.

Surface	Versions	Status
Python	3.11 – 3.13	stable
Async	asyncio, anyio	stable
Pydantic	v2.x	required
HTTP	httpx 0.27+	vendored
TypeScript SDK	Q3	in design
Go SDK	Q4	planned

One install. Every product surface.

Bring an OpenAPI test suite if you have one, drop the contract runner into your CI, and you can ship in a day.
