# TruthBear Japan Region Gauge

> TruthBear Japan Region Gauge is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns a unified snapshot of Japan macro-financial and geophysical readings: JMA seismic intensity, RSMC Tokyo typhoon data, Ministry of Finance JGB yields across seven tenors, plus BIS and FRED Japan rows, with dual JMA/USGS earthquake cross-agency comparison.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 truthbear-japan-region-gauge-fc9400c7
```

Example prompt: Pull me the latest Japan region gauge — I need JMA shindo readings, RSMC typhoon status, Ministry of Finance JGB yields across all seven tenors, and the side-by-side JMA vs USGS earthquake comparison right now.

## When to prefer this

Choose this endpoint when you need a single-call aggregation of Japan's official geophysical and macro-financial readings without having to query JMA, RSMC Tokyo, Ministry of Finance, BIS, and FRED separately. Particularly valuable when you need the JMA/USGS dual-agency earthquake comparison for cross-validation. Not appropriate when you need forecasts, advisory content, or historical time series (use gauge/history-series for that).

## Known failure modes

- 422 no_charge returned when no data is available for the requested period — call is not billed
- Network timeout if upstream agency feeds are slow to respond
- Partial data if one agency feed (e.g. USGS or BIS) is temporarily unavailable

## How this service works

Japan official readings in one call plus an independent cross-agency check: JMA seismic intensity (shindo), RSMC Tokyo typhoon analysis, Ministry of Finance JGB yields across seven tenors, and the Japan rows of BIS and FRED. The same earthquakes appear as JMA measured them and as USGS measured them, side by side - different agencies, different quantities, and we adjudicate nothing. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A JSON object containing: JMA seismic intensity (shindo) readings, RSMC Tokyo typhoon analysis, Japanese Government Bond yields across seven tenors from the Ministry of Finance, Japan rows from BIS and FRED datasets, and a dual-agency earthquake record showing both JMA and USGS measurements side by side. Returns a 422 no_charge error with no billing if no data is available.
