## 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 usage-bill-reconstructor-mcp-scores-tools-2192789c -d '<json body>'
```

Example prompt: Can you reconstruct and verify my usage bill — I need to check whether my invoice total of $27.46 matches my actual usage across request meters and storage meters, and flag any discrepancies?

## When to prefer this

Choose this endpoint when you need to programmatically verify, reconstruct, or audit a usage-based bill with tiered pricing structures, fixed charges, and metered consumption — especially when reconciling an invoice total against raw usage quantities. Prefer it over manual spreadsheet calculations or generic math tools when dealing with multi-tier pricing with included quantities and mixed fixed/variable charges.

## Known failure modes

- Missing or malformed usage data returns error
- Mismatched currency or unit assumptions produce incorrect totals
- Tier boundary miscalculations if included_quantity is omitted
- Payment failure via x402 returns 402 before analysis runs
- Invalid meter IDs result in unrecognized meter errors

## How this service works

Customer-input analysis tools with per-call x402 v2 USDC payments on Base. Discovery and examples are free.

## Output

Returns a JSON object with ok status, an array of billing meters each containing tiered quantity/unit-price/cost breakdowns, total charges in minor units, fixed charges (platform fees, support plans), the overall currency, whether the reconstructed total matches the invoice, and the difference if any.
