124 available in the API response. 4.6. ICU (Broker) An authenticated API approach is used in two steps: first obtaining an access token, then requesting market quotes. Data sources: https://auth.online.icu/api/auth/token/ (authentication). After receiving the access token, this token must be added as authorization header to https://trade- mw.online.icu/api/quotes (market data endpoint). Nested fields are flattened and normalized. The collected data includes quote identifiers, ISIN/instrument metadata, bid/ask or last-price values, yield indicators, and additional quote attributes exposed by the API. This is the most integration-heavy scenario, as it requires managing secrets. 4.7. Univer (Broker) Headless scraping of a dynamic page is used, including clicking ―load more‖ buttons to fully expand data before parsing. Source: https://univer.ua/products. A text parser is then applied, and the collected data includes ISIN, currency, price, maturity date, and yield. The project combines three main classes of data collection strategies: • Public API ingestion (BTC Broker) • Authenticated API ingestion with token management (ICU) • Browser-based scraping of dynamic pages with DOM/text parsing and user interaction emulation (PrivatBank, Raiffeisen, PUMB, Kinto, Univer). On top of these, a unified MCP orchestration layer standardizes module execution, manages available scenarios, ensures output format, and exposes data to consumers through a single interface. The collected and normalized results are stored in CSV files. 5. Conclusion The paper addresses the applied scientific problem of collecting and integrating data on Ukrainian domestic government bonds (OVDP) as a foundation for the further application of intelligent hybrid methods for analyzing temporal and contextual data in financial analytics. The key characteristics of OVDP are identified,
