xwapi 0.9.0.11

Convenience wrapper for exonware-xwapi - provides 'import xwapi' alias

xwapi

Build once, publish anywhere. xwapi is the entity- and exposable-action layer for eXonware: define xwaction operations and xwentity models once, then publish them over HTTP/OpenAPI (bots, consoles, and other adapters align to the same contracts). It also supports the other direction — clients and agents that consume those actions via XWApiAgent and related client engines.

Default HTTP engine is FastAPI (full OpenAPI/async ecosystem); Flask is a registered alternate so you can swap ASGI vs WSGI at app construction without rewriting actions. See docs/REF_24_ALTERNATIVES.md for comparable libraries and engine notes.

Beyond HTTP wiring: standardized errors, production middleware, durable action pipeline, API token lifecycle/metering.

📦 Install

Install	When to use
pip install exonware-xwapi	Core runtime
pip install exonware-xwapi[lazy]	Lazy dependency loading
pip install exonware-xwapi[full]	Full production dependency set
pip install exonware-xwapi[engines-http]	Optional HTTP engines (Starlette, Quart, Sanic, aiohttp, BlackSheep, Litestar, Django, Mangum)

---

🚀 Quick start

from exonware.xwapi import XWAPI
from exonware.xwentity import XWEntity


class User(XWEntity):
    name: str
    email: str
    age: int


api = XWAPI(entities=[User], title="My API", version="1.0.0")
app = api.create_app(engine="fastapi")

🆕 New production features

• Engine-agnostic error contract: xwapi_error_to_http_parts plus adapters keeps XWAPIError transport-neutral.
• Outbox + singleton worker pipeline: ActionPipelineManager, AOutboxStore/InMemoryOutboxStore, and BackgroundWorker.
• API token lifecycle: create/list/revoke tokens, usage tracking, balance/recharge, idempotent metering.
• Provider abstractions: IAuthProvider, IStorageProvider, IPaymentProvider with in-memory and library adapters.
• API token middleware: bearer verification, optional scope enforcement, deny-unmapped policy, usage metering via Idempotency-Key.
• Admin/operations endpoints: server status/health/pipeline controls and token admin endpoints.
• Production guardrails: environment-based admin token enforcement and admin read-protection support.

---

💻 Client side

Use XWApiAgent (and client engines) to discover XWAction methods, attach auth/session flows, and treat remote APIs as the consumer half of the same exposable-action model.

---

🔗 eXonware integration

xwapi now explicitly integrates with:

• xwsystem (serialization, logging/utilities)
• xwaction (action registration and execution)
• xwentity (entity-driven API surfaces)
• xwschema (schema validation/generation integration points)
• xwdata (data/serialization integration paths)

🌐 Ecosystem functional contributions

For xwapi, each XW library covers a specific feature and requirement boundary rather than acting as a generic dependency layer. You can use xwapi standalone with its core install and existing non-XW components. Adding more XW packages is optional and mainly useful when you want full enterprise and mission-critical infrastructure patterns under your own control.

Supporting XW lib	What it provides to xwapi	Functional requirement it satisfies
XWAction	Metadata, registration, execution, and engine adapters for exposable actions (HTTP, and other surfaces).	Same business action from server publish to client consume; reusable across FastAPI/Flask engines.
XWEntity	Entity-first domain surface that xwapi can expose directly as API resources.	Stable domain contracts and lower boilerplate for CRUD/API scaffolding.
XWSystem	Shared error and runtime foundations (logging, config, async/helpers, transport-neutral utility layers).	Uniform API behavior across FastAPI/Flask/GraphQL/gRPC and predictable ops behavior in production.
XWSchema	Validation and schema integration points for request/response shaping and API contracts.	Strong input/output contract enforcement and safer API evolution.
XWStorage	Persistence abstraction used by server pipeline components and token/admin paths where durable state is needed.	Durable action/outbox/token workflows instead of in-memory-only behavior.
XWAuth	Authentication/authorization provider integrations used by middleware and protected routes.	API security requirements (token validation, authz boundaries, tenant-safe access).
XWData	Data transformation/serialization support for mixed payloads and format conversion paths.	Multi-format payload handling without duplicating conversion logic in endpoint code.

This is the practical edge: one place composes publish (server) and consume (agent/client) paths around the same exposable actions, instead of stitching unrelated libraries per service.
