The Financial data from Yahoo!
| ### \*\*\* Key Points to Note \*\*\* --- **All financial data is sourced from Yahoo!Ⓡ Finance, Nasdaq!Ⓡ, and the U.S. Department of the Treasury via publicly available APIs, and is intended for research and educational purposes.** I will update the data regularly, and you are welcome to follow this project and use the data. Each time the data is updated, I will record the update time in [spec.json](https://huggingface.co/datasets/defeatbeta/yahoo-finance-data/blob/main/spec.json). |
Data Usage Instructions
Use DuckDB or Python API or Terminal or AI Agents, including Claude Desktop, Manus, Codex, Hermes Agent, OpenClaw Agent, and others, to access data.
When using defeatbeta-api, version 0.0.61 or later is required. Earlier versions use the legacy flat data/ paths and are incompatible with the current market-specific directory layout.
All datasets are publicly accessible. Tabular datasets are stored in Parquet format, while instrument catalogs are stored in JSON format.
