How businesses use Polymarket US + Lyro
Each card is one request a support team gets, and the Polymarket US actions Lyro runs to close it.
Find the market behind a question
Lyro searches public markets and events in natural language, narrows by tag, sport, or league, and returns the specific market, so the answer points at a real slug rather than an approximation.
Search Markets and EventsList MarketsGet Market by SlugPreview an order before it goes live
Lyro reads the best bid and offer, runs the signed preview that validates the parameters without submitting anything, and places the live order only once someone has confirmed the exact details.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Polymarket US actions it has and picks the ones a request needs.
Connect Polymarket US
Authorize the Polymarket US account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Polymarket US actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.
