Swagger Petstore - OpenAPI 3.0 SDK

The Swagger Petstore - OpenAPI 3.0 SDK for Python provides access to the Swagger Petstore - OpenAPI 3.0 REST APIs from Python applications.

This is a sample Pet Store Server based on the OpenAPI 3.0 specification. You can find out more about Swagger at https://swagger.io. In the third iteration of the pet store, we've switched to the design first approach! You can now help us improve the API whether it's by making changes to the definition itself or to the code. That way, with time, we can improve the API in general, and expose some of the new features in OAS3.

Installation

To install the Python SDK from PyPI, with whichever package manager your project uses:

pip install wesley-key-sdk

uv add wesley-key-sdk

poetry add wesley-key-sdk

To install from the SDK source instead, give the tool a path containing a slash — a bare folder name is looked up on PyPI, and resolves to whatever project holds that name there:

pip install <path-to-sdk>

Quick Start

Synchronous client

Construct SwaggerPetstoreOpenApi30Client with keyword arguments, and call close() when you are done. Every argument is optional; the full list is in the SDK map.

from swagger_petstore_open_api_3_0 import SwaggerPetstoreOpenApi30Client

client = SwaggerPetstoreOpenApi30Client(petstore_auth="YOUR_API_KEY", api_key="YOUR_API_KEY")

# TODO: call endpoints here -- see api-reference.md

client.close()

Alternatively, scope it -- with SwaggerPetstoreOpenApi30Client(...) as client: closes the pool on exit; see Best Practices.

Client is exported as an alias of SwaggerPetstoreOpenApi30Client, so from swagger_petstore_open_api_3_0 import Client also works.

The SDK accepts every model-typed input in two interchangeable spellings, both type-checked: the typed model, or a plain dict with the same keys -- the OrDict and Model | ModelDict unions in the SDK map. Pick whichever suits the call site: the dict form needs no import, while the model form adds a keyword-checked constructor and editor completion.

Asynchronous client

AsyncSwaggerPetstoreOpenApi30Client mirrors SwaggerPetstoreOpenApi30Client with identical method names, and every endpoint method is a coroutine. It takes the same arguments, with some differences -- for example, the transport argument is custom_async_http_client.

from asyncio import run

from swagger_petstore_open_api_3_0 import AsyncSwaggerPetstoreOpenApi30Client


async def main() -> None:
    client = AsyncSwaggerPetstoreOpenApi30Client(petstore_auth="YOUR_API_KEY", api_key="YOUR_API_KEY")
    # TODO: call endpoints here, awaiting each -- see api-reference.md
    await client.aclose()


run(main())

Alternatively, scope it -- async with AsyncSwaggerPetstoreOpenApi30Client(...) as client: closes the pool on exit. Only the async spelling is aclose, matching httpx2; see Best Practices.

AsyncClient is the exported alias. Each client accepts only its own transport argument; passing the other's is a TypeError at runtime and an error under mypy.

Usage

Two generated references cover the SDK; each answers a different question:

Both API references carry every one of the 19 operations, with a sync and an async sample and a parameter table each.

SDK map

This SDK ships a generated SDK map -- sdk-map.md -- a deterministic, lookup-oriented table of contents of the SDK's Python surface, generated by APIMatic alongside this SDK.

Consult the map before scanning or grepping the source: it answers call-level contract questions by lookup, and for anything it does not carry -- model shapes, enum values, an endpoint's route or behavioural prose -- it names the one source file to read. How to read the map itself, including the SDK-wide defaults its rows rely on, is stated at the top of sdk-map.md.

Best Practices

Match the disposal to the client's lifetime: an application-lifetime client is closed once at shutdown with close() / aclose(); where the lifetime fits a block, with SwaggerPetstoreOpenApi30Client() as client: / async with AsyncSwaggerPetstoreOpenApi30Client() as client: releases it automatically. Both are idempotent, but a closed client is not reusable: the next call raises. The client closes whatever transport it holds, including one you supplied via custom_http_client / custom_async_http_client; if you intend to reuse your own transport across clients, don't hand its lifetime to a with block.

Retries are on by default: a failed idempotent request — a retryable status or no response at all — is sent again up to three times before the call gives up. Pass retry_options=0 to turn it off, for instance in a test that stubs an error response; the policy and its defaults are under Retries in the SDK map.
