Odds Raven is an informational aggregator, not a trading platform. The data is for reference — nothing here is financial advice. Be reasonable with our API. Do not redistribute the data in bulk without asking. We disclaim warranties and limit liability to $100. Questions: hello@oddsraven.com.
These Terms of Service ("Terms") are a legal agreement between you and Odds Raven ("we", "us", "our") governing your use of the website at oddsraven.com, the public API served from it, and any other services we operate (collectively, the "Service"). By accessing or using the Service, you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not use the Service.
If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.
Odds Raven is an independent aggregator of publicly available prediction market data. We fetch data from public APIs operated by third-party prediction market platforms (including but not limited to Polymarket, Manifold Markets, PredictIt, and Gemini Predictions), compute cross-platform consensus probabilities using published aggregation methods, and display the results on the Site.
Odds Raven is not a prediction market operator, broker, exchange, or trading venue. You cannot place bets, buy contracts, or transfer money through the Service. We have no commercial relationship with the platforms whose data we aggregate unless specifically stated in writing.
The probabilities, charts, and commentary displayed on the Service are informational only. Nothing on the Service constitutes, or should be interpreted as:
Prediction markets are speculative. Past accuracy does not guarantee future accuracy. Consensus probabilities are statistical aggregations of public market prices, not forecasts of certainty. You are responsible for your own decisions. Consult a licensed professional before making financial, legal, or medical decisions based on any information on the Site.
All market data on the Service is sourced from public APIs operated by third-party prediction market platforms. Each market card, question page, and event page links to its source of origin. We attribute every data point to the platform it came from.
We make reasonable efforts to keep data fresh and accurate, but we do not control the upstream sources. If a third-party API is unavailable, rate-limits us, changes format, or returns incorrect data, that will be reflected on the Service until the issue is resolved. We are not responsible for the accuracy, completeness, or availability of upstream data.
If you are a prediction market platform and you believe our use of your public data is inappropriate or requires a different license arrangement, please contact us at hello@oddsraven.com.

The design, layout, written explanations, methodology documentation, consensus computation code, matching pipeline, SVG logo, and other original creative work produced by Odds Raven are our intellectual property or are used with permission. You may reference them under the permitted uses in Section 5, but you do not acquire ownership rights by using the Service.
The underlying market data displayed on the Service belongs to the respective source platforms. We aggregate it under the terms published by those platforms and under general principles of public data use. If you want to use that data for purposes beyond our permitted uses, you should review the source platform's own terms, which govern your use of their data.
Thumbnail images displayed on cards are hotlinked from the source platform's CDN and remain the property of the respective platform or its licensors. We do not copy, cache, or modify these images.
The Service links to third-party prediction market platforms. We are not affiliated with, endorsed by, or sponsored by any of those platforms unless explicitly stated. When you leave Odds Raven by clicking an outbound link, you are subject to the destination site's terms and privacy policy, not ours. We have no control over, and accept no responsibility for, the content, operations, or practices of any third-party site.
We offer a public JSON API at /api/v1/questions. API access is subject to these Terms plus the following additional rules:
If you need higher rate limits, a partnership, or commercial licensing, email us.
We strive for accurate data but we make no guarantee of accuracy. Upstream APIs change, markets get relabeled, our cross-platform matcher occasionally produces wrong matches, and edge cases exist. If you spot an error, please report it to hello@oddsraven.com and we will investigate.
The Service is provided without any uptime guarantee. We run on a single server and may be unavailable for maintenance, upgrades, or due to issues outside our control. Mission-critical use cases are not an appropriate fit for the Service at this time.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR ACCURACY. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. YOU USE THE SERVICE AT YOUR OWN RISK.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES. IN THOSE JURISDICTIONS, THE EXCLUSIONS IN THIS SECTION APPLY ONLY TO THE FULLEST EXTENT PERMITTED BY LAW.
TO THE FULLEST EXTENT PERMITTED BY LAW, ODDS RAVEN AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, LOSS OF DATA, TRADING LOSSES, OR BUSINESS INTERRUPTION, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
IN ANY CASE, OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE IS LIMITED TO ONE HUNDRED UNITED STATES DOLLARS (USD 100).
You agree to indemnify, defend, and hold harmless Odds Raven and its operators from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or in any way connected with (a) your use of the Service, (b) your violation of these Terms, or (c) your violation of any rights of a third party, including any prediction market platform whose data you access via the Service.
We respect intellectual property rights. If you believe content on the Service infringes your copyright, send a notice to hello@oddsraven.com with the following information:
We will review valid notices and remove infringing material where appropriate. Repeated bad-faith notices may be reported to appropriate authorities.
We may update these Terms from time to time. When we do, we will update the effective date at the top of this page and describe the change in our changelog. Material changes will be announced with at least 14 days' notice before taking effect. Your continued use of the Service after the effective date of an update constitutes acceptance of the updated Terms.
We may suspend or terminate your access to the Service at any time, with or without notice, if we believe you have violated these Terms or if continued access poses a risk to the Service or to other users. Because the Service does not require an account, "termination" in practice means network-level blocking.
You may stop using the Service at any time. No account deletion is necessary because no account exists.
These Terms are governed by the laws of the operator's jurisdiction, without regard to conflict-of-laws rules. Any dispute arising out of or relating to these Terms or the Service shall be resolved exclusively in the courts of that jurisdiction, and you consent to their personal jurisdiction. This choice of law does not deprive you of the protection afforded by mandatory provisions of the law of your country of habitual residence, if applicable.
We believe strongly in informal resolution. Before filing a legal action, please contact us and describe the issue — we will make a good-faith effort to resolve it.
Entire agreement. These Terms, together with our Privacy Policy, are the entire agreement between you and Odds Raven regarding the Service and supersede any prior agreements.
Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect.
No waiver. Our failure to enforce any right or provision of these Terms is not a waiver of that right or provision.
Assignment. You may not assign these Terms. We may assign them to a successor in connection with a merger, acquisition, or sale of assets.
No partnership. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and Odds Raven.
Headings. Section headings are for convenience only and do not affect interpretation.
