Route difference
The first layer is not brand size. It is user market, protocol entry, model-family coverage, and real call stability.

Comparison summary
How to judge first
Anthropic and Amazon are both on the global route, so compare protocol, model coverage, and key visibility.
Anthropic has broader catalog coverage, but broader coverage does not mean every key can call every model.
In production, one key should reveal provider identity, callable models, balance or quota signals, limits, and risk notes.
Key checking value
A key may expose only part of the models, interfaces, or regions, so the final call must rely on detection results, not the catalog alone.

Procurement and distribution
For procurement, agency, and marketplace listing, provider comparison must end in supply stability, pricing, monitoring, and model updates.
- Do not treat catalog coverage as real sellability.
- Key checking and continuous monitoring are the final commercial loop.
