Internal service for querying electronic component suppliers. It provides a unified HTTP API that centralizes vendor credentials and provider routing.

Status

2026.6.5 - standalone service, Python client, Appliku deployment signoff, and PyPI publishing setup.

The PyPI distribution is supply-chain-monkey. The Python import package is scm.

Architecture

The repo contains three layers:

• scm.models: shared contract with Pydantic models, enums, and supplier constants.
• scm.client: HTTP client library for consumers.
• scm.server: FastAPI server with provider adapters and the status page.

Providers

Supplier	Backend	Credentials Required
JLCPCB	Hybrid official API plus scraper	Optional; scraper works without credentials
LCSC	Internal JSON API	None
Digikey	Official REST API v4 OAuth2	Yes
Mouser	Official REST API v1	Yes

API

All endpoints except health require a bearer token.

GET  /v1/health
GET  /v1/providers/status
GET  /v1/search?supplier=jlcpcb&mpn=TPS543620RPYR
GET  /v1/detail?supplier=jlcpcb&part=C2870085
GET  /v1/search/stream?mpn=X&token=Y

The streaming endpoint pushes results per provider as they complete via Server-Sent Events. It supports max_results and per-provider timeout.

The root URL serves a status page with an interactive test panel.

Client Library

Install the consumer client from PyPI:

python -m pip install "supply-chain-monkey[client]==2026.6.5"

from scm.client import SCMClient
from scm.models import PARAMETER_FIELD_NAMES, SUPPLIERS, SupplierType

client = SCMClient(url="https://your-scm.example.com", token="...")

result = client.search("jlcpcb", "TPS543620RPYR")
all_results = client.search_all("TPS543620RPYR")
detail = client.detail("jlcpcb", "C2870085")
print(SUPPLIERS)

Local Development

cp .env.template .env
# fill in SCM_SERVICE_TOKEN and any provider credentials

uv sync --group dev
PYTHONPATH=src/py uv run uvicorn scm.server.main:app --reload --env-file .env

Testing

uv run pytest -q
uv run rack run L99_signoff
uv run python tests/scripts/scm_test_cli.py --token YOUR_TOKEN
uv run python tests/scripts/scm_test_cli.py --url https://your-scm.example.com --token YOUR_TOKEN

Deployment

The included appliku.yml uses Appliku's managed python-3.13-uv build image. Pushing production can trigger deployment.

git checkout dev
# merge through PRs; do not develop directly on production

pyproject.toml must keep [tool.uv] package = false and default-groups = []. The Dockerfile is inactive unless appliku.yml changes to build_image: dockerfile. See CLAUDE.md for deployment constraints.

dev is the integration branch. main is the public source branch. production is the Wavenumber deployment branch and must be updated only by protected PR/merge flow.

Consumer Integration

Consumers should depend on the supply-chain-monkey[client] distribution and import scm. Configure service URL and token outside source control.
