astroway

Official Python SDK for the AstroWay API — natal charts, synastry, transits, Vedic dashas, Tarot, Numerology, Human Design, AI horoscopes. Sync + async, type-hinted, retry-aware.

700+ endpoints. Synchronous and asynchronous clients with the same surface. Built-in retry on 408/409/429/5xx with exponential backoff. Stainless-style error hierarchy (AuthenticationError / RateLimitError / BadRequestError / …). Just httpx + pydantic under the hood.

Install

pip install astroway
# or with uv
uv add astroway
# or with poetry
poetry add astroway

Get an API key at https://api.astroway.info/dashboard/sign-up — 10 000 credits/month free, no card required. Each endpoint costs 5–500 credits depending on what it computes (pricing).

Requires Python 3.9+.

Quick start

Synchronous

from astroway import Astroway

aw = Astroway(api_key="aw_live_...")

chart = aw.post("/chart", body={
    "date": "1990-07-14",
    "time": "14:30:00",
    "timezoneOffset": 3,
    "latitude": 50.45,
    "longitude": 30.52,
    "houseSystem": "P",
})

asc = chart["angles"]["asc"]
print(f"ASC: {asc['sign']} {asc['degree']:.2f}°")

Asynchronous

import asyncio
from astroway import AsyncAstroway

async def main() -> None:
    async with AsyncAstroway(api_key="aw_live_...") as aw:
        chart = await aw.post("/chart", body={
            "date": "1990-07-14",
            "time": "14:30:00",
            "timezoneOffset": 3,
            "latitude": 50.45,
            "longitude": 30.52,
        })
        print(chart["angles"]["asc"])

asyncio.run(main())

The two clients share an identical surface — same constructor params, same methods (get, post, put, delete, low-level request), same error types.

Common workflows

Synastry

result = aw.post("/synastry", body={
    "chart1": {"date": "1990-07-14", "time": "14:30:00", "timezoneOffset": 3, "latitude": 50.45, "longitude": 30.52},
    "chart2": {"date": "1992-03-22", "time": "09:15:00", "timezoneOffset": 2, "latitude": 48.85, "longitude": 2.35},
})
print(f"Score: {result['compatibility']['score']}/100 ({result['compatibility']['label']})")

Transits to natal

transits = aw.post("/transits", body={
    "date": "1990-07-14", "time": "14:30:00", "timezoneOffset": 3, "latitude": 50.45, "longitude": 30.52,
    "targetDate": "2027-01-01",
})

Vedic Vimshottari Mahadasha

dasha = aw.post("/vedic/dashas/vimshottari/maha", body={
    "date": "1985-07-22", "time": "06:45:00", "timezoneOffset": 5.5,
    "latitude": 19.07, "longitude": 72.87,
})

Tarot reading

spread = aw.post("/tarot/rider-waite/spread", body={"spreadType": "three-card", "seed": 42})

Human Design

hd = aw.post("/human-design", body={
    "date": "1990-07-14", "time": "14:30:00", "timezoneOffset": 3, "latitude": 50.45, "longitude": 30.52,
})
print(f"{hd['type']} — {hd['strategy']} — {hd['authority']}")

Error handling

The SDK raises typed subclasses of ApiError. Catch order matters — most specific first:

from astroway import (
    Astroway, ApiError,
    AuthenticationError, RateLimitError, BadRequestError,
)

try:
    aw.post("/chart", body=body)
except RateLimitError as e:
    time.sleep(e.retry_after_seconds or 60)
    # retry once...
except AuthenticationError:
    raise RuntimeError("Rotate your AstroWay API key")
except BadRequestError as e:
    print("Validation failed:", e.body)
except ApiError as e:
    print(f"API error {e.status} ({e.code}): {e!s} [request_id={e.request_id}]")

Full hierarchy:

• ApiError (base)
  • APIConnectionError
    • APITimeoutError
  • BadRequestError (400)
  • AuthenticationError (401)
  • PermissionDeniedError (403)
  • NotFoundError (404)
  • UnprocessableEntityError (422)
  • RateLimitError (429) — carries retry_after_seconds
  • InternalServerError (5xx)

Configuration

aw = Astroway(
    api_key="aw_live_...",                  # required
    base_url="https://api.astroway.info/v1", # override for staging / self-hosted
    auth_scheme="header",                    # "header" (X-Api-Key, default) or "bearer" (Authorization: Bearer)
    timeout=30.0,                            # per-request timeout in seconds
    retry={
        "max_retries": 2,                    # total attempts = 1 + max_retries
        "base_delay_ms": 250,
        "max_delay_ms": 30_000,
        "retryable_statuses": frozenset({408, 409, 429, 500, 502, 503, 504}),
    },
    default_headers={"X-Trace-Id": "..."},
)

The default retry honors Retry-After (seconds or HTTP-date) on 429 responses.

Set retry={"max_retries": 0} to disable retries entirely.

---

Authentication

Two equivalent auth schemes — pick whichever your stack prefers:

• Header (default): X-Api-Key: aw_live_... — same convention as curl/Postman examples.
• Bearer: Authorization: Bearer aw_live_... — same convention as Stripe/OpenAI/Anthropic SDKs.

Set via auth_scheme="bearer" in the constructor.

---

Privacy

The SDK does not phone home. There is no telemetry, no analytics, no usage reporting. The only network traffic the SDK originates is the AstroWay API calls you ask it to make.

Outgoing requests carry two identifying headers so the AstroWay backend can distinguish SDK traffic from raw HTTP traffic in its own logs:

• User-Agent: astroway-sdk-python/<version> (Python/<py-version>; <platform>)
• X-Astroway-Channel: sdk-py

Neither carries a session ID, machine fingerprint, or anything personal.

---

Stability

• Public API stable inside a major version. Methods/classes shipped under 1.x won't be renamed or removed without a deprecation note in CHANGELOG.md and a one-minor parallel-availability window.
• Body shape stable inside a minor version. Tightening (constraints, enum) ships in patches; new required keys require a minor bump.
• API version vs SDK version are independent. SDK 0.x follows its own semver; the API itself sits at /v1/.
