ai2web

AI2Web Python SDK (ai2web)

The Python reference implementation of the AI2Web protocol - for Django, Flask, FastAPI, or plain Python. Mirrors @ai2web/core.

pip install ai2web

from ai2web import ai2web, validate, handle

manifest = (
    ai2web({"name": "Example Store", "url": "https://example.com", "type": "ecommerce"})
    .capability("content")
    .capability("commerce", {"endpoint": "/ai2w/products", "checkout": True})
    .transports({"mcp": {"enabled": True, "endpoint": "/ai2w/mcp"}, "rest": {"enabled": True}})
    .auth({"methods": ["none", "oauth2"], "oauth2": {"pkce": True, "scopes": ["checkout"]}})
    .consent({"requires_user_approval_for": ["purchase"]})
    .contact({"support": "help@example.com"})
    .build()
)

result = validate(manifest)          # {'score': 90+, 'tier': 'Standard', ...}

# Serve every AI2Web route from one call (framework-agnostic):
res = handle({"manifest": manifest}, method, path, body, origin)

Modules

• ai2web.manifest - fluent capability-model builder (ai2web(...), Manifest).
• ai2web.validator - validate() + AI Readiness scoring (spec §9/§11).
• ai2web.negotiator - negotiate() capability negotiation (spec §5).
• ai2web.server - handle() framework-agnostic route handler.
• ai2web.safety - is_safe_public_url() / assert_safe_public_url() SSRF guard.
• ai2web.export - to_llms_txt() / to_agent_json() projections of the manifest (RFC-0015).

The builder also carries the v0.2 optional modules - .governance(...), .usage_policy(...), .legal(...), .agent_identity(...), .knowledge(...) - and actions accept intent and bindings. All are additive: a minimal manifest stays valid without them.
