First useful task

Check funding, a covered bank, and liquidity.

  1. Check coverage first. Run Release identity, Dataset coverage and Source status. Check the returned source dates and limits.
  2. Run one research request. Choose Money Markets, Bank Risk or Market Liquidity. Examples return up to five rows so you can inspect the contract.
  3. Keep the evidence together. Cite source URLs and native dates. Preserve unavailable values and rights labels. Follow pagination with the complete-capture research kit.
  4. Return for your next review. Compare saved captures on another day and identify which source observations changed.

Coverage

Choose the evidence your task needs.

money_markets, money_market_history, capital_markets, bank_risk, market_liquidity, china_economy and source_health.

Coverage varies by dataset and source. A successful response does not certify freshness, complete pagination or redistribution rights. The API returns these boundaries for you to assess.

Current coverage boundaries

At the 7 October 2026 check, the money-market view returned 19 rows while the underlying atlas reported partial coverage. The China routes reported restricted or unavailable evidence. Dataset names identify query routes, not a promise that all observations are available or current.
