unitysvc-sellers 0.1.4

Seller-facing tools for UnitySVC: HTTP SDK + usvc_seller CLI

unitysvc-sellers

Python SDK and CLI for the UnitySVC seller API (https://seller.unitysvc.com/v1). This package provides:

1. unitysvc_sellers — a typed Python package (sync Client + async AsyncClient) that wraps the upstream REST API into importable, type-checked method calls.
2. usvc_seller — a CLI built on top of the SDK for day-to-day seller operations (catalog management, secret rotation, service lifecycle) without writing code.

Install

pip install unitysvc-sellers

This pulls in unitysvc-core for the shared data models, JSON schemas, and generic file validator; plus httpx, attrs, typer, and rich.

Programmatic usage

from unitysvc_sellers import Client

client = Client(api_key="svcpass_...")  # or Client.from_env()

# List services
services = client.services.list(limit=50, status="active")
for s in services.data:
    print(s.name, s.id)

# Fetch full record
detail = client.services.get(service_id)

# Update service status
client.services.set_status(service_id, {"status": "ready"})

# Promotions (idempotent upsert by name)
client.promotions.upsert({
    "name": "summer-2026",
    "scope": {"customers": "*"},
    "pricing": {"type": "multiply", "factor": "0.80"},
    "status": "active",
})

# Service groups
group = client.groups.upsert({"name": "premium", "service_ids": [...]})

# Push an entire catalog directory
result = client.upload("./my-catalog", dryrun=False)
print(f"services: {result.services.success}/{result.services.total}")

Configuration

Source	Default	Override
API key	(required)	Client(api_key=...) / UNITYSVC_SELLER_API_KEY
Base URL	https://seller.unitysvc.com/v1	Client(base_url=...) / UNITYSVC_SELLER_API_URL
Timeout	30 s	Client(timeout=...)

The seller context is encoded entirely in the API key (svcpass_...), so no separate seller_id argument is required.

Env var naming: env vars are namespaced to the seller role (UNITYSVC_SELLER_API_KEY, UNITYSVC_SELLER_API_URL) so a single host can run both the seller SDK and the future customer SDK side by side without collision — each picks up its own credentials.

URL layout: the SDK's generated paths are semantic resource paths (/services/{id}, /documents/{id}, /promotions, /service-groups) with no /seller wrapper. The seller scope is carried by the subdomain + API key. The same generated SDK works against any deployment layout without regeneration:

# Default: production seller subdomain
Client()  # reads UNITYSVC_SELLER_API_URL or defaults to
          # https://seller.unitysvc.com/v1

# Staging
Client(base_url="https://seller.staging.unitysvc.com/v1")

# Local development against a running backend
Client(base_url="http://localhost:8000/v1/seller")

Secrets

Manage encrypted seller secrets (API keys, tokens, credentials). Values are write-only — only metadata is ever returned.

# List all secrets (metadata only)
secrets = client.secrets.list()
for s in secrets.data:
    print(s.name, s.created_at)

# Get one secret's metadata by name
meta = client.secrets.get("OPENAI_API_KEY")

# Create a new secret
client.secrets.create("OPENAI_API_KEY", "sk-...")

# Rotate (update) the value
client.secrets.rotate("OPENAI_API_KEY", "sk-new-...")

# Delete a secret (immediate effect on running services)
client.secrets.delete("OPENAI_API_KEY")

Methods:

Method	Parameters	Returns	Description
secrets.list(skip=0, limit=100)	skip, limit	SecretsPublic	List secrets (metadata only)
secrets.get(name)	name: str	SecretPublic	Get one secret's metadata
secrets.create(name, value)	name: str, value: str	SecretPublic	Create a secret (upsert)
secrets.rotate(name, value)	name: str, value: str	SecretPublic	Rotate an existing secret's value
secrets.delete(name)	name: str	None	Permanently delete a secret

Secret names must be uppercase with underscores (e.g. OPENAI_API_KEY, STRIPE_SECRET). Names starting with __ are reserved for platform use.

Pagination

services.list, promotions.list, and groups.list use cursor-based pagination. Each call returns a CursorPage* response with data, next_cursor, and has_more:

# Single page
page = client.services.list(limit=50)
for s in page.data:
    print(s.name)

# Full iteration
cursor = None
while True:
    page = client.services.list(cursor=cursor, limit=100)
    for s in page.data:
        yield s
    if not page.has_more or not page.next_cursor:
        break
    cursor = page.next_cursor

The CLI list commands accept --cursor and --all (to auto-follow cursors and render the combined result).

Async client

The same API surface is exposed as AsyncClient for use in asyncio contexts (FastAPI, Starlette, Trio-via-anyio, scripts using asyncio.run):

import asyncio
from unitysvc_sellers import AsyncClient

async def main():
    async with AsyncClient(api_key="svcpass_...") as client:
        services = await client.services.list(limit=50)
        for s in services.data:
            print(s.name)

        await client.promotions.update(promo_id, {"status": "active"})

asyncio.run(main())

Each async method has the exact same signature as its sync counterpart on Client. The remote usvc_seller services|promotions|groups commands all use AsyncClient under the hood.

Errors

All errors are subclasses of unitysvc_sellers.SellerSDKError:

from unitysvc_sellers import (
    SellerSDKError,
    AuthenticationError,   # 401
    PermissionError,       # 403
    NotFoundError,         # 404
    ValidationError,       # 400, 422
    ConflictError,         # 409
    RateLimitError,        # 429
    ServerError,           # 5xx
    APIError,              # base for everything above
)

Each carries status_code, detail (parsed body if JSON), and response_body for debugging.

CLI: usvc_seller

The CLI has two sets of commands:

• usvc_seller data ... — local seller catalog operations (no network)
• usvc_seller services|promotions|groups ... — remote operations against the seller backend, all using the SDK's AsyncClient under the hood

Local commands

usvc_seller data validate [DATA_DIR]            # schema + catalog-layout validation
usvc_seller data format   [DATA_DIR]            # normalize JSON/TOML/MD files
usvc_seller data populate [DATA_DIR]            # run provider populate scripts
usvc_seller data show     provider|offering|listing|service NAME
usvc_seller data list     providers|sellers|offerings|listings|services [DATA_DIR]
usvc_seller data list-tests                     # list local code-example / connectivity tests
usvc_seller data run-tests                      # run them locally
usvc_seller data show-test SERVICE              # show last local test result
usvc_seller data upload   [DATA_DIR]            # upload services + promotions + groups
        [--api-key svcpass_...]                 #   defaults to $UNITYSVC_SELLER_API_KEY
        [--base-url https://...]                #   defaults to $UNITYSVC_SELLER_API_URL or staging
        [--type services|promotions|groups]     #   restrict to one resource kind
        [--dryrun]                              #   validate against backend without persisting

Remote commands (require $UNITYSVC_SELLER_API_KEY or --api-key)

# Services
usvc_seller services list [--status STATUS] [--name NAME] [--provider NAME]
                          [--fields id,name,...] [--format table|json]
usvc_seller services show SERVICE_ID [--format table|json]
usvc_seller services submit    SERVICE_IDS... | --all [--provider NAME] [--yes]
usvc_seller services withdraw  SERVICE_IDS... | --all [--provider NAME] [--yes]
usvc_seller services deprecate SERVICE_IDS... | --all [--provider NAME] [--yes]
usvc_seller services delete    SERVICE_IDS... | --all [--status STATUS]
                              [--provider NAME] [--dryrun] [--yes]
usvc_seller services update SERVICE_ID
        [--set-routing-var key=value | '{json}']        (repeatable)
        [--remove-routing-var key]                       (repeatable)
        [--load-routing-vars path/to.json]
        [--set-price key=value | '{json}' | NUMBER]      (repeatable)
        [--remove-price-field key]                       (repeatable)

# Document tests (registered under services for parity with the legacy CLI)
usvc_seller services list-tests   [SERVICE_ID] [--all] [--status STATUS]
                                  [--format table|json]
usvc_seller services show-test    DOCUMENT_ID [--format table|json]
usvc_seller services run-tests    SERVICE_ID [--document-id DOC_ID] [--force]
usvc_seller services skip-test    DOCUMENT_ID
usvc_seller services unskip-test  DOCUMENT_ID

# Promotions
usvc_seller promotions list   [--format table|json]
usvc_seller promotions show     NAME_OR_ID [--format table|json]
usvc_seller promotions activate NAME_OR_ID
usvc_seller promotions pause    NAME_OR_ID
usvc_seller promotions delete   NAME_OR_ID [--force]

# Service groups
usvc_seller groups list   [--status STATUS] [--format table|json]
usvc_seller groups show    NAME_OR_ID [--format table|json]
usvc_seller groups delete  NAME_OR_ID [--force]

# Secrets
usvc_seller secrets list   [--format table|json]
usvc_seller secrets show   NAME [--format table|json]
usvc_seller secrets create NAME [--value VALUE | --value-file PATH | --value-stdin]
usvc_seller secrets rotate NAME [--value VALUE | --value-file PATH | --value-stdin]
usvc_seller secrets delete NAME [--force]

promotions activate / pause are sugar over PATCH /promotions/{id} with a status field — the backend consolidated the legacy /activate and /pause routes.

The legacy usvc services dedup command is not ported because the backing endpoint was removed; use services delete --all --status draft instead.

The legacy usvc_seller groups refresh command is not ported either. Dynamic group membership is now refreshed automatically by a background worker whenever a group is mutated, so there's no manual refresh step for sellers to invoke.

Regenerating the API client

The low-level client under src/unitysvc_sellers/_generated/ is produced by openapi-python-client from a filtered copy of the backend OpenAPI spec at openapi.json. To regenerate after a backend change:

# Requires a sibling checkout of unitysvc/unitysvc with backend/.venv set up
./scripts/generate_client.sh ../unitysvc

This script:

1. Dumps /v1/openapi.json from the backend's running app via scripts/dump_spec.py.
2. Filters to seller-tagged operations and sanitizes schema names that contain characters openapi-python-client cannot parse (e.g. strips the auto-generated pydantic title from anonymous inline object schemas to avoid Pricing / Terms collisions).
3. Runs openapi-python-client generate with the config in scripts/openapi-python-client.yml.

The hand-written facades in unitysvc_sellers/{client,resources}.py should rarely change when the spec is regenerated; only the operation modules under _generated/api/seller/ and the models under _generated/models/ get refreshed.

History

This package was split out of unitysvc-services (see issue #99). Shared types + schemas live in unitysvc-core; seller CLI, the catalog HTTP SDK, and seller-specific catalog utilities live here.

Roadmap

• unitysvc_sellers.builders — catalog-builder helpers (populate_from_iterator, render_template_file, etc.) for unitysvc-services-* data repositories.
• Attachment-bytes upload — once the backend defines its replacement for the old /seller/documents/upload-attachment endpoint, the client.upload(...) orchestrator will inline binary file content again instead of requiring external_url references.
