Follow source-linked news and ticker video coverage, or read the latest published Market Update with its chapters.

Validate CSV/JSON tables and convert dated amounts to EUR, alongside sourced historical exchange rates, country economic indicators and international public-holiday calendars. Free MCP pilot; no account, API key or wallet required for these tools. Practical tasks: - validate_table: check explicit column types, required values, date/decimal formats, allowed values and duplicate keys. Preserve original rows and explain requested normalization. No row deletion, guessed dates or independent verification of the contents. - convert_currency_batch: convert decimal-string amounts to EUR using exact-date ECB historical references, with explicit rounding, original amounts and source evidence. A missing, stale or mismatched rate blocks the complete export and total; no silent replacement by another date. Try: validate a table of invoice references, amounts and dates; or convert 125.50 USD dated 2025-09-26 to EUR and explain the source rate and rounding. Start with a small batch. Maximum 500 rows and 48,000 UTF-8 argument bytes; tables allow 20 columns and conversions eight currency/year snapshots. JSON by default; output_format=both adds CSV in the same free result when complete. DatoQA processes supplied rows in memory and does not retain their content. Your client or gateway may keep its own logs. Existing data tools remain available. Holiday coverage combines direct FR/UK/HK government calendars with the international OpenHolidays curated collection. Consult list_holiday_regions for actual countries, years and regional scope; coverage is not exhaustive worldwide and future dates may change. OpenHolidays entries do not have individual government confirmation. Responses preserve citations, observation dates, units, freshness, evidence and explicit gaps. Original public data, including ECB rates, is free from its publishers. ECB references are indicative, not executable prices or accounting/tax certification. Source/schema checks are not independent factual verification. Public pilot without an SLA. The optional paid HTTP country report remains separate and is never purchased by these tools. 26 general MCP tools. Setup, examples and focused editions: https://datoqa.bhazarstudio.workers.dev/docs/start/
