API & Data License
These terms apply to the Bourse API (api.bourse.pl), the MCP server, webhooks, bulk downloads and nightly exports. They add to the [Terms of Use](/legal/terms/). By creating an API key you accept them.
Plans
Free and Premium API keys are for personal, non-commercial use: your own research, models, spreadsheets and tools that only you use.
Bourse API Pro is a paid business plan (499 USD a month or 4,990 USD a year, plus any applicable tax). It includes a commercial license described below, higher limits, up to 10 API keys, nightly full-dataset exports and priority email support. Larger volumes, custom feeds or delivery to your own storage are available on request (Enterprise).
What API Pro lets you do
- show Bourse data inside your own app, website, dashboard or internal tools, to your users or clients;
- use the data in research, trading models, signals and AI systems, including ones you sell;
- quote and chart the data in newsletters, reports, articles and videos;
- store the data you receive for as long as your API Pro subscription is active, and keep reports you already published after it ends.
What is not allowed on any plan
- reselling or redistributing the raw data as a standalone dataset, feed or API (for example a competing data product or a data marketplace listing);
- presenting the data as your own, without attribution;
- sharing API keys outside your organisation, or using several accounts to get around limits;
- using the data in a way that breaks the law or the terms of the original public sources.
Attribution
When you show Bourse data to other people, credit it as "Data: Bourse (bourse.pl)" near the data or in your sources section. Some underlying sources have their own credit requirements (for example WARN Feed, CC BY 4.0); see Data & compliance.
Public sources and their rules
Bourse data comes from public records (SEC EDGAR, House and Senate disclosures, the Office of Government Ethics, the Senate Lobbying Disclosure Act database, USAspending, FEC and others). Some of those records come with their own restrictions. In particular, U.S. law restricts using financial disclosure reports of government officials (such as OGE Form 278) for commercial purposes other than by news and communications media, and for certain solicitation purposes. You are responsible for checking that your use of each dataset complies with those rules. This is not legal advice.
Limits and fair use
Each plan has request limits per minute and per day. Over a limit the API answers with HTTP 429. We may temporarily limit a key that harms the service for others, and we will tell you why.
Billing and cancellation
API Pro is billed in advance through Stripe, monthly or yearly, and renews automatically until you cancel in the billing portal. After cancellation the plan stays active until the end of the paid period, then the key falls back to the free limits. Invoices with your VAT ID are available in the billing portal.
No warranty, not investment advice
The data is provided as is. We work to keep it accurate and up to date, but public filings contain errors and delays, and parsing and AI extraction can make mistakes. Check important facts against the original filing (every row links to its source where available). Nothing in the API is investment advice. To the extent the law allows, our liability is limited to the fees you paid in the last 12 months.
Changes and contact
We may change these terms or the API. For material changes that affect API Pro we will give at least 30 days' notice by email. Questions, Enterprise requests and support: bourse.official@gmail.com.
