## 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 japan-government-bond-auction-results-by-tenor-e96991df
```

## When to prefer this

Choose this endpoint when you need authoritative, structured JGB auction data directly from the Japan Ministry of Finance — particularly when you need per-tenor filtering, historical series, or precise price/yield/amount fields for fixed-income analysis, macro research, or compliance workflows. Prefer over scraping MOF website directly or using general financial data providers that may lag or aggregate.

## Known failure modes

- Missing required 'tenor' parameter returns validation error
- Invalid tenor value (not in allowed enum) returns 400 error
- limit out of range (must be 1-200) returns validation error
- No auction data available for requested tenor returns empty list
- Upstream MOF data unavailability may result in stale or missing records
- Payment failure (x402) blocks access if USDC payment not processed
