Every channel below is read. Which one to use depends on what the message is about.

Report a bad read

The fastest route is the site itself. Every verdict has a flag on it: use it on the check that looked wrong, and the report arrives with the bet, the slate it was matched against and the numbers the simulator produced. That is far more useful than a description of the problem, because the same bet can be re-graded against the same simulations later.

Reads worth flagging: a bet matched to the wrong game, a player the checker did not recognise, a price it read incorrectly from a screenshot, or a probability that looks impossible for the matchup.

Ask a question

Questions about a market, a number on a research page, or how a verdict was reached are answered publicly wherever they are asked:

Coverage and feature requests

Sports and markets are added when the simulator can grade them honestly, not when there is demand for them, so a request is a signal about priority rather than a queue position. Ask on any channel above and the answer will say where the sport actually stands.

Building on NegativeEV

The machine-readable surface — the MCP server, the markdown mirrors, the API catalog and the agent skills index — is documented at https://negativeev.com/about/for-agents. Questions about integrating with it go to the same channels.

Shared packages from the project are published under https://github.com/jessejohnsohn.

Legal and privacy

What the site records, and what it never does, is on the privacy page: https://negativeev.com/privacy. The terms of use are at https://negativeev.com/terms.
