# OCC Listed Options Daily

`GET /v1/data/us-equity-opt-ref/occ-list-opt-daily`

The OCC Listed Options Daily dataset is derived from the official Options Clearing Corporation (OCC) Directory of Listed Products and provides comprehensive daily coverage of all equity, index, and currency options listed on U.S. public exchanges. The dataset includes core reference attributes such as the OCC-designated option symbol, underlying symbol, option name, underlying security type, and applicable position limits. It serves as an authoritative daily snapshot of the U.S. listed options universe, enabling users to accurately track option availability, reference identifiers, and listing characteristics over time. Data is available on a daily basis starting July 2023, and is designed to support historical research, universe construction, compliance monitoring, and institutional-grade options reference workflows.

 For more details, please refer to the dataset documentation: [OCC Listed Options Daily Guide](https://us-options-reference-docs.s3.us-east-1.amazonaws.com/algoseek.OCC.Daily.Listed.Options.pdf).
