A useful Claude Code API relay should be boring in the best way: predictable request handling, straightforward
configuration, and documentation that matches the live behavior. Start by checking whether it accepts the same shape
of request your current client already sends. Then verify whether streaming, retry handling, and model selection work
the way your team expects.
During early evaluation, avoid over-optimizing for flashy marketing claims. Instead, focus on practical criteria:
response consistency, how errors are surfaced, whether rate limits are easy to interpret, and whether the relay
supports the control points you need for debugging. If you are comparing providers, a structured smoke test is far
more useful than reading a feature list.
In many Claude Code setups, the best approach is to keep the environment small: one base URL, one key, one model
target, and a simple prompt that you can repeat. That makes it easier to identify whether a failure comes from your
app, the relay, or the upstream service. It also helps when you are evaluating 按量付费 usage because each test call
has a visible cost and a clear outcome.
