Bursting /v1/keys is a product failure, not a bad actor

New developers often burn starter quotas before noon while following a quickstart. Hard 429s without a thread feel hostile. Soft docs updates never reach the person who already left.

Capture RATE_LIMIT failures with the key bootstrap path and reply in the inbox with backoff guidance.

Make the limit visible in the moment

A probe that opens a thread can explain quota and attach a snippet with exponential backoff. That is more effective than a status page they will not check.

Feed product, not only support

If many evaluators hit the same 429, raise the starter ceiling or fix the sample code. Watch rules help you notice spikes before a sales deal dies quietly.

Capture the failure before they leave

Capture the failure before they leave. Book early access or talk to sales, then install @aethellayer/sdk when you are onboarded.
