Is this name on Japan's MOF asset-freeze list? Hosted, list-change history kept. Reference only.
Convert dated amounts to a supported target currency with traceable ECB reference rates, or retrieve recent and historical EUR reference exchange rates since 1999. Exact source dates, original decimals, citations and explicit gaps. New practical task: convert_currency_batch accepts rows with a unique id, date, currency and decimal-string amount. It preserves original amounts, source rate decimals and evidence, applies an explicit rounding rule and returns a line-by-line result. Missing, stale or mismatched rates block the complete CSV and total. A weekend date is never silently replaced by a previous working day. Try: convert 125.50 USD dated 2025-09-26 to EUR and explain the rate and rounding. Up to 500 rows, 48,000 UTF-8 argument bytes and eight currency/year snapshots per call. Start small. JSON is the default; output_format=both adds CSV in the same free result. EUR rows use identity, not an external rate. DatoQA processes supplied rows in memory without retaining their content; your client or gateway may keep its own logs. Existing tools still provide exact-date/year history and latest references. Source availability varies by currency and year; no forward filling or interpolation. Original ECB data is free. References and derived conversions are indicative, not live executable prices, transfers or accounting/tax certification. Source/schema checks are not independent factual verification. 7 focused MCP tools. Free during the pilot; no account, API key or wallet required. Same DatoQA source snapshots as the general server; public pilot without an SLA. Setup, examples and limits: https://datoqa.bhazarstudio.workers.dev/docs/fx/ Datoka portal and connection guide: https://datoka.dev/qa.
