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.

What this package manages

The package is organized around the kinds of data a seller works with. Each has a CLI command group and an SDK namespace.

There are two routes to a service on the platform: author full specs and specs upload them, or pick a template and supply params to instantiate it. specs upload also carries any groups and promotions you author alongside them (service_group.* / promotion.* files, upserted by name) — so those, too, are seller-authored, not platform-only. services, secrets, and the templates catalog are managed directly on the platform. Both the usvc_seller CLI and the Python SDK cover every domain.

→ Full docs: Services (the spec model + the two routes + status lifecycle) · Service Templates (platform templates, capability pools, your own populators) · File Schemas (every field and option).

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 — iterate the page directly (the result is a ServiceList).
for svc in client.services.list(limit=50, status="active"):
    print(svc.id, svc.name, svc.status)

# Fetch one — `svc` is a Service active-record bound to its id.
svc = client.services.get(service_id)
print(svc.name, svc.status)

# Mutate via the bound handle (no need to re-pass the id).
svc.update({"status": "pending"})
svc.submit()  # shortcut for {"status": "pending"}

# Promotions — upsert returns a Promotion bound to its id.
promo = client.promotions.upsert({
    "name": "summer-2026",
    "scope": {"customers": "*"},
    "pricing": {"type": "multiply", "factor": "0.80"},
    "status": "active",
})
promo.update({"status": "paused"})

# Service groups — same pattern.
grp = client.groups.upsert({"name": "premium", "service_ids": [...]})
grp.update({"display_name": "Premium tier"})

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

Configuration

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. The API mirrors GitHub's secrets API: set(name, value) is idempotent and covers both create and rotate.

# 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 or rotate (idempotent)
client.secrets.set("OPENAI_API_KEY", "sk-...")

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

Methods:

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 an iterable list wrapper (ServiceList, PromotionList, GroupList) that exposes data, next_cursor, has_more, and next_page():

# Single page — iterate the wrapper directly
page = client.services.list(limit=50)
for svc in page:
    print(svc.name)

# Manual pagination via next_page()
while page.has_more:
    page = page.next_page()
    for svc in page:
        ...

# Or let the SDK walk every page for you
for svc in client.services.iter_all(status="active"):
    print(svc.name)

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). Sync iteration walks the current page; for full iteration use iter_all():

import asyncio
from unitysvc_sellers import AsyncClient

async def main():
    async with AsyncClient(api_key="svcpass_...") as client:
        # One page at a time.
        services = await client.services.list(limit=50)
        for svc in services:
            print(svc.id, svc.name)

        # Or every page, automatically:
        async for svc in client.services.iter_all(status="active"):
            print(svc.id, svc.name)

        # Active-record mutations work the same way.
        promo = await client.promotions.get(promo_id)
        await promo.update({"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 specs ... — local operations on a specs/ repo (no network)
• usvc seller services|params|templates|promotions|groups|secrets ... — remote operations against the seller backend, all using the SDK's AsyncClient under the hood

Local commands (specs)

usvc seller specs validate [SPECS_DIR]           # schema + catalog-layout validation
usvc seller specs format   [SPECS_DIR]           # normalize JSON/TOML/MD files
usvc seller specs populate [SPECS_DIR]           # run the repo's populator (templates/config.json)
usvc seller specs show     SERVICE_NAME          # expanded data for one service
usvc seller specs list     services|providers|offerings|listings|sellers [SPECS_DIR]
usvc seller specs list-tests [NAME]              # list local code-example / connectivity tests
usvc seller specs run-tests  [NAME]              # run them locally
usvc seller specs show-test  SERVICE             # show last local test result
usvc seller specs upload     [NAME]              # 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

NAME is a service_name (= listing.name) — a literal or an fnmatch pattern ('cohere/*'); omit it to act on the whole repo.

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

# Services — NAME is a service_name (= listing.name), literal or fnmatch pattern
usvc seller services list [NAME] [--status STATUS] [--provider NAME]
                          [--fields id,name,...] [--format table|json]
usvc seller services show           [NAME] [--format table|json]
usvc seller services submit         [NAME] | --all [--provider NAME] [--yes]
usvc seller services withdraw       [NAME] | --all [--provider NAME] [--yes]
usvc seller services deprecate      [NAME] | --all [--provider NAME] [--yes]
usvc seller services set-visibility VISIBILITY [NAME] | --all   # public|unlisted|private
usvc seller services delete         [NAME] | --all [--status STATUS] [--yes]
usvc seller services update [NAME]
        [--visibility public|unlisted|private]
        [--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; NAME selects services, doc ids select docs)
usvc seller services list-tests   [NAME] [--all] [--format table|json]
usvc seller services show-test    [DOCUMENT_ID] [--format table|json]
usvc seller services run-tests    [NAME] [--document-id DOC_ID] [--force]
usvc seller services skip-test    DOCUMENT_ID
usvc seller services unskip-test  DOCUMENT_ID

# Templates + params — create a service from a platform template
usvc seller templates list
usvc seller templates show NAME_OR_ID
usvc seller params instantiate TEMPLATE [-P key=value ...] [--name NAME]
                               [--submit | --no-submit]

# 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 set    NAME [--value VALUE | --value-file PATH | --value-stdin]   # create or rotate
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.

Claude Code skill

This repository ships a Claude Code skill at skills/writing-unitysvc-services/SKILL.md. Installed into <your-repo>/.claude/skills/ or ~/.claude/skills/, it teaches Claude the platform's file-organization rules, naming conventions, and the validate → format → local-tests → gateway-tests → upload pipeline, so Claude can author services to spec without you having to thread every rule into the prompt each time. See Claude Code Skill for install + usage.

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.
