## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability quota-overage-biller-mcp-b32eeb5b -d '<json body>'
```

Example prompt: Process overage billing for my API account — the usage data shows we exceeded our monthly quota and I need to calculate and submit the overage charges for billing.

## When to prefer this

Choose this endpoint when you need to programmatically process and bill quota overage charges for API or SaaS usage — particularly in metered billing workflows where consumption exceeds predefined plan limits and automated charge processing is required. It is best suited for agentic workflows that need to trigger billing actions at the end of billing cycles or in real time when quota thresholds are crossed.

## Known failure modes

- Invalid or malformed data payload returns a 400 error
- Quota or usage data missing required fields causes processing failure
- Payment processing failure if billing backend is unavailable
- Ambiguous or incomplete overage calculation data leads to rejected request
- Service timeout for large or complex billing data sets
