A call your balance cannot cover is refused with HTTP 402 before any upstream is contacted. - A charged call that then fails upstream is refunded automatically. - Retries are ordinary calls. There is no client idempotency key, so repeating a request that was already charged buys a second call - see [agent.txt](https://gateway.mcpharbor.dev/agent.txt), section 7.
