SAFI / DEVELOPER HUB / v1.1
Build a purchasing agent on facts.
One commercial engine. Two documented interfaces. Start with structured requests and leave payment decisions with the customer.
01 ↗
Send your first request
Keys, request shape and a quote you can inspect.
02 ↗Connect through A2A
Discover the Agent Card and exchange structured messages/tasks.
03 ↗Work through real limits
Unknown prices, review routing and a disabled checkout outcome.
The response is useful because its limits are explicit.
Every interface uses the same catalog, quote ownership, pricing arithmetic, review policy and checkout validation. A protocol task may finish preparing a response while its quote still needs human review. No model is needed to invent an answer.
