Your provider invoice says what you spent. It cannot say which feature spent it.
This is two minutes of traffic through the MainStreet Observer — 1,400 requests, each tagged with the feature that made it. Press play and watch what a month of the same traffic costs, with and without acting on what the audit finds.

We read, never rewrite
Requests and responses pass through untouched. We extract tokens, latency, and cost from the response stream after it has already reached you.
You get the findings
Which feature spends what, which calls are over-provisioned, and the dollar figure attached to each fix — computed from your own traffic.
See this for your own traffic
Two weeks of your real traffic through the observer, and we hand back the same breakdown you just watched — built from your workloads, not ours. The audit is free and there’s nothing to commit to afterwards.
One email to start a conversation. No account required.
What you are watching
Real: every row is one request that actually went through the proxy — recorded tokens, measured latency, cost computed at published provider rates. All four findings were produced by the recommendation rules reading this run’s own telemetry, not chosen by hand — one workload was deliberately left alone, because nothing about it needed fixing.
The comparison: the right pane re-prices each recorded request as if the finding had been acted on — a cheaper model where one fits, caching turned off where it isn’t paying for itself, no charge for output that got truncated. The Observer is read-only: it identifies the opportunity; you decide whether to act on it.
Simulated: this recording ran against a mock provider, so the token counts and latencies are synthetic and no provider was billed. Monthly figures project the recorded throughput of 11.4 requests/second across 30 days — one stated multiplier over a measured number.
