## 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-mof-fx-intervention-record-api-b365274c
```

Example prompt: Pull the 100 most recent Japan Ministry of Finance yen foreign-exchange intervention records so I can see the dates, amounts, and currency pairs for each operation.

## When to prefer this

Choose this endpoint when you need authoritative, official MOF-sourced records of Japan's yen FX intervention operations with exact dates and amounts, especially for historical analysis from 1991 onward. Prefer over general financial data APIs when you specifically need Japan government intervention data rather than market price data or third-party estimates.

## Known failure modes

- Invalid 'since' date format returns an error — must be ISO date string
- 'limit' outside 1-500 range may be rejected or clamped
- No results returned for date ranges with no recorded interventions (not an error, just an empty list)
- Payment failure via x402 if insufficient USDC balance
- Network timeout for very large result sets

## How this service works

Individual yen foreign-exchange intervention operations (date, amount, currency pair) from the Ministry of Finance's official record, 1991-present. Quarters with no intervention are simply absent from the list rather than zero-padded. Factual published data only; not investment advice or a signal to trade on.

## Output

A list of individual FX intervention operation records from Japan's Ministry of Finance, each containing the date of the operation, the monetary amount intervened, and the currency pair involved. Quarters with no intervention are absent from results rather than zero-padded. Results are returned most-recent-first and can be filtered by a lower-bound date and limited in count.
