Worth writing about

• A combo that priced oddly. Send the legs, the price you were quoted and roughly when. Most reports of a wrong number turn out to be a market whose outcome names we read the wrong way round, which is a quick fix once it is pointed out.
• A market or a sport we are missing. ComboCheck lists what Polymarket marks as combo-enabled; if something you can combo there is absent here, that is a bug.
• The API or the MCP server. Questions, a field you need, or a rate limit in your way: see the developer page first, then write.
• Listing ComboCheck in a directory or a guide, or asking about the data behind today's numbers.

What this is not

ComboCheck is independent and not run by Polymarket, so nothing here can move your money, place a bet, resolve a market or reach your account. For any of that, ask Polymarket's own support. ComboCheck never asks for a wallet, a private key or funds, and no email from us will ever ask for one either.

Other ways

Code-level bugs and feature requests are also welcome as issues on GitHub. Everything the site knows is public: the methodology says where each number comes from.
