rerout 0.2.0

Official Python SDK for the Rerout branded-link API.

rerout

Official Python SDK for the Rerout API.

Branded link infrastructure on Cloudflare. Create short links, render QR codes, read analytics, and verify webhook signatures.

Install

pip install rerout
# or
uv add rerout
# or
poetry add rerout

Requires Python 3.10+.

Usage

from rerout import Rerout, CreateLinkInput

rerout = Rerout(api_key="rrk_...")

link = rerout.links.create(
    CreateLinkInput(
        target_url="https://example.com/q4-sale",
        domain_hostname="go.brand.com",
        code="q4",
    )
)
print(link.short_url)  # https://go.brand.com/q4

stats = rerout.project.stats(days=7)
print(f"Last 7 days: {stats.total_clicks} clicks, {stats.qr_scans} QR scans")

The client can be used as a context manager to ensure the underlying HTTP connection pool is closed:

with Rerout(api_key="rrk_...") as rerout:
    link = rerout.links.get("q4")

API

Construction

from rerout import Rerout

rerout = Rerout(
    api_key="rrk_...",                  # required
    base_url="https://api.rerout.co",   # optional, defaults shown
    timeout=30.0,                       # optional, seconds
    client=None,                        # optional, inject your own httpx.Client
)

Inject a custom httpx.Client for proxies, retries, or shared connection pools. The SDK does not close clients it didn't create.

Links

from rerout import CreateLinkInput, UpdateLinkInput

rerout.links.create(CreateLinkInput(target_url=..., domain_hostname=..., code=...))
rerout.links.list(cursor=None, limit=None)
rerout.links.get(code)
rerout.links.update(code, UpdateLinkInput(target_url=...))
rerout.links.delete(code)
rerout.links.stats(code, days=30)

Every Link carries a read-only tags tuple — each Tag has an id, name, and color. Tags are populated on get, list, and update responses (empty on create), and cannot be written through the SDK; the API ignores tag writes for API-key clients.

link = rerout.links.get("q4")
for tag in link.tags:
    print(tag.name, tag.color)

UpdateLinkInput uses an UNSET sentinel to distinguish "leave this field alone" from "clear this field on the server" — pass None to clear, or just don't pass the field at all:

from rerout import UpdateLinkInput

# Clear the expiry, leave everything else untouched
rerout.links.update("q4", UpdateLinkInput(expires_at=None))

# Disable the link without touching SEO
rerout.links.update("q4", UpdateLinkInput(is_active=False))

Calling update with an UpdateLinkInput where no field has been set raises ReroutError(code='bad_request') without hitting the API.

Project

rerout.project.stats(days=30)  # -> ProjectStats
rerout.project.me()            # -> ProjectInfo

QR codes

from rerout import QrOptions

# Pure URL builder — no network call
rerout.qr.url("q4", QrOptions(size=12, ecc="H", domain="go.brand.com"))

# Fetches the rendered SVG with the bearer token attached
svg = rerout.qr.svg("q4", QrOptions(refresh=True))

QR options:

Field	Type	Notes
size	int	Module size in px. 1–32. Server default 8.
margin	int	Quiet zone in modules. 0–16. Server default 4.
ecc	'L' | 'M' | 'Q' | 'H'	Error correction level.
domain	str	Force the QR to encode a specific verified custom domain.
refresh	str | bool	Cache-bust on regenerate. True is sent as 1; strings pass through.

Webhook signature verification

from rerout import verify_rerout_signature

ok = verify_rerout_signature(
    raw_body=request.body.decode(),
    signature_header=request.headers["x-rerout-signature"],
    secret=settings.REROUT_WEBHOOK_SECRET,
)
if not ok:
    return Response(status=401)

Defaults to a 5-minute timestamp tolerance; pass tolerance_seconds=0 to disable that check.

Error handling

Every method raises ReroutError on failure:

from rerout import Rerout, ReroutError, CreateLinkInput

try:
    rerout.links.create(CreateLinkInput(target_url="http://insecure.example"))
except ReroutError as err:
    print(err.code)     # 'bad_target_url'
    print(err.status)   # 400
    print(err.message)  # 'target_url must use https.'
    if err.is_rate_limited:
        ...  # back off

Synthetic codes when the server didn't return a JSON body: network_error, timeout, unexpected_response, unauthorized, forbidden, not_found, rate_limited, server_error, client_error, missing_api_key, bad_request.
