yaci-store-api-client

A client library for accessing Yaci Store API.

This library is mostly generated using OpenAPI Generator.

Usage

First, create a client:

from yaci_client import Client

client = Client(base_url="http://localhost:8080", raise_on_unexpected_status=True)

If the endpoints you're going to hit require authentication, use AuthenticatedClient instead:

from yaci_client import AuthenticatedClient

client = AuthenticatedClient(base_url="https://localhost:8080", token="SuperSecretToken")

Now call your endpoint and use your models:

import json
from yaci_client.api.local_epoch_service import (
    get_latest_protocol_params,
)
from yaci_client import Client
from yaci_client.models import (
    ProtocolParamsDto,
)
from yaci_client.types import Response

client = Client(base_url="http://localhost:8080", raise_on_unexpected_status=True)

with client as client:
    params: ProtocolParamsDto = get_latest_protocol_params.sync(client=client)
    print(params)

    response: Response[ProtocolParamsDto] = get_latest_protocol_params.sync_detailed(client=client)
    protocol_params_json = json.loads(response.content)
    print(protocol_params_json)

Or do the same thing with an async version:

import json
from yaci_client.api.local_epoch_service import (
    get_latest_protocol_params,
)
from yaci_client import Client
from yaci_client.models import (
    ProtocolParamsDto,
)
from yaci_client.types import Response

client = Client(base_url="http://localhost:8080", raise_on_unexpected_status=True)

async with client as client:
    params: ProtocolParamsDto = await get_latest_protocol_params.asyncio(client=client)
    response: Response[ProtocolParamsDto] = await get_latest_protocol_params.asyncio_detailed(client=client)

By default, when you're calling an HTTPS API it will attempt to verify that SSL is working correctly. Using certificate verification is highly recommended most of the time, but sometimes you may need to authenticate to a server (especially an internal server) using a custom certificate bundle.

import ssl

from yaci_client import AuthenticatedClient

client = AuthenticatedClient(
    base_url="https://localhost:8080",
    token="SuperSecretToken",
    verify_ssl=ssl.create_default_context(cafile="/path/to/certificate_bundle.pem"),
)

You can also disable certificate validation altogether, but beware that this is a security risk.

from yaci_client import AuthenticatedClient

client = AuthenticatedClient(base_url="https://localhost:8080", token="SuperSecretToken", verify_ssl=False)

Things to know:

1. Every path/method combo becomes a Python module with four functions:

   1. sync: Blocking request that returns parsed data (if successful) or None
   2. sync_detailed: Blocking request that always returns a Request, optionally with parsed set if the request was successful.
   3. asyncio: Like sync but async instead of blocking
   4. asyncio_detailed: Like sync_detailed but async instead of blocking

2. All path/query params, and bodies become method arguments.

3. If your endpoint had any tags on it, the first tag will be used as a module name for the function (my_tag above)

4. Any endpoint which did not have a tag will be in yaci_client.api.default

Advanced customizations

There are more settings on the generated Client class which let you control more runtime behavior, check out the docstring on that class for more info. You can also customize the underlying httpx.Client or httpx.AsyncClient (depending on your use-case):

from yaci_client import Client


def log_request(request):
    print(f"Request event hook: {request.method} {request.url} - Waiting for response")


def log_response(response):
    request = response.request
    print(f"Response event hook: {request.method} {request.url} - Status {response.status_code}")


client = Client(
    base_url="https://api.example.com",
    httpx_args={"event_hooks": {"request": [log_request], "response": [log_response]}},
)

# Or get the underlying httpx client to modify directly with client.get_httpx_client() or client.get_async_httpx_client()

You can even set the httpx client directly, but beware that this will override any existing settings (e.g., base_url):

import httpx
from yaci_client import Client

client = Client(
    base_url="https://localhost:8080",
)
# Note that base_url needs to be re-set, as would any shared cookies, headers, etc.
client.set_httpx_client(httpx.Client(base_url="https://localhost:8080", proxy="http://localhost:8030"))

Installation

pip install yaci-client

It needs Python 3.11 or newer and works with httpx 0.25.1 up to 0.28.

Development

The project uses uv, ruff, ty and just. Run just to list every task.

just sync       # install the project and its development tools
just check      # lint, type-check and test
just test-all   # the tests on every supported Python

yaci_client is generated from the Yaci Store OpenAPI spec in yaci_api.json by openapi-python-client. After updating the spec, run just regenerate; ruff then formats the result, so it passes just lint. Review the diff before committing: newer generators rename fields (for example type to type_), which breaks callers, so a rename belongs in a major release.

Commits follow Conventional Commits. Run uv run pre-commit install once to check messages and formatting on each commit.

Releasing

1. just bump sets the version and the changelog from the commits since the last release, and tags it vX.Y.Z.
2. Push the commit and the tag: git push --follow-tags.
3. The tag starts the Release workflow, which builds the package, publishes it to PyPI with Trusted Publishing (no token in the repository) and creates the GitHub release.
