Terms of Service

Last updated:June 2026. By using DepthFeed's website, API, or data you agree to these terms.

The service

DepthFeed provides sports prediction-market data — order-book depth, market settlements, and joined real-world results, odds, and injury data — delivered over REST and WebSocket. Access is tied to a plan and an API key. Don't share your key, exceed your plan's rate limits, or attempt to disrupt the service.

Data & accuracy

We work hard to capture data faithfully and describe our methods honestly — including publishing the verification rate of our market-to-game mapping — but the data is provided "as is," without warranty of completeness or fitness for a particular purpose. Upstream sources can lag or contain errors; injury alerts reflect when our sources update, not when news breaks. Nothing here is betting or financial advice. You are responsible for your own decisions.

Acceptable use

  • Use the data for research, analysis, modeling, and your own trading.
  • Do not resell or redistribute bulk datasets without written permission.
  • Do not use webhooks to target systems you do not control.
  • Do not use the service for anything unlawful, including where sports wagering is prohibited.

Plans & billing

DepthFeed plans are monthly. Sports REST is included on every tier; a scoped seven-day production evaluation is available on request. See the official DepthFeed pricing page for current inclusions and billing terms.

Cancellation

You can cancel anytime; your plan stays active through the period you've already paid for, after which paid access ends.
