## Price

- $0.0001 (100 micro-USD) per tool call.
- Billed on: each tools/call that reaches the upstream and returns a result.
- Free: server/discover, tools/list, registry endpoints, docs files.
- Payment: prepaid credits, drawn down per call. 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.
