Orestar API
Orestar API is a community-provided API for accessing public campaign finance disclosures made by candidates for public office in Oregon. All of this information exposed via this API is available publicly on a system called Orestar for anyone to query. However, Orestar has a number of technical limitations that make it difficult to work with:
- A web-browser must be used to manually browse the data.
- Only a single browser tab can be used to query for campaign finance disclosures.
- Only a maximum of 5,000 transactions can be obtained per-query.
For citizens or researchers that want to look at old records, or correlate records across candidates, these limitations are debilitating.
This is a community supported project
The Orestar API collects information off of orestar, and exposes it in easy to consume CSV files via an API. This is a community project, not affiliated with Orestar or the Government of Oregon. All of the information on this site should match equivalent queries done on Orestar, though we don't make any guarantees about accuracy. If you need perfect accuracy, then we recommend the laborious process of querying information directly from Orestar.
Finally, Orestar exposes fairly detailed records about campaign contributions including employment details and addresses for some contributors. Given that the Orestar API makes accessing this information much easier, we have opted to omit this information from our exports.
