🔧 Input reference

Field	Type	Default	What it does
currency_pair_filter	string (USD-JPY, EUR-JPY, GBP-JPY, all)	"all"	Restrict to a specific currency pair, or 'all' for every pair (and to include quarterly summary rows). Default 'all'.
date_from	string	empty = one year ago (Console example "2022-01-01")	Inclusive lower bound for the intervention report_date (ISO YYYY-MM-DD). Leave empty for one year ago.
date_to	string	empty = today	Inclusive upper bound for the intervention report_date (ISO YYYY-MM-DD). Leave empty for today, so the newest MoF disclosures are always included.
intervention_only	boolean	true	When true, exclude zero-intervention months (¥0 reports). Set false to include the full historical series including zero months. Default true.
max_records	integer	25	Maximum number of intervention records to emit (1-500). Default 100.

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
FX intervention record (fx-intervention-record)	$0.05	Per Japan MoF FX intervention disclosure

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.

📊 What you get

Clean JSON, one record per record (full output has 20 fields):

• amount_JPY_millions — Amount JPY millions
• amount_USD_equivalent_at_intervention_rate — USD equivalent in millions, using the USD/JPY rate on the intervention day (FRED series DEXJPUS, Federal Reserve noon New York rate). Quarterly totals use the average daily rate over the quarter, so those are estimates; rate_source says which rate each row used
• amount_oku_yen_raw — Amount oku yen raw
• base_currency — Base currency
• currency_pair — Currency pair
• description_en — Description en
• description_jp — Description jp
• estimation_rate_USDJPY — the USD/JPY rate used for the USD equivalent
• rate_source — which rate was used: the intervention-day rate, the quarter average (estimate), or annual_average_estimate if the daily series could not be reached
• rate_date — the date of the daily rate used (nearest earlier business day if the intervention day had no fix)
• fetched_at — Fetched at
• fiscal_year_jp — Fiscal year jp
• period_start / period_end — quarterly-summary period (YYYY-MM)

Pricing: $0.05 per delivered record (Pay-Per-Event fx-intervention-record) — about 20 records per $1. Records are charged only when delivered; a run that matches nothing charges nothing.

Agentic payments (x402): Supports agentic payment via x402 — agents can call this actor with USDC, no API key required.

⏰ Run on a schedule

This is a monitoring play — schedule a recurring pull:

{
  "currency_pair_filter": "USD-JPY",
  "date_from": "2026-01-01",
  "date_to": "2026-12-31",
  "max_records": 50
}

Japan intervenes rarely — most months are zero. A run with no matching interventions succeeds with 0 records and costs nothing.
