API Documentation
Build on the DecisionLayer API to file arbitration cases by contract, create consent cases, run a simulation, and track which cases need your action. Or skip the code: connect ChatGPT, Claude, Cursor or any MCP client to the same API and ask in plain language.
Create a Case by Consent
Create a consent case and inspect a schema-accurate response in the Python playground.
Try it live →Create a Case by Contract
File a case in one call, finish signing, payment, and identity
verification at the returned action_url,

Run a Simulation
Submit every argument and response in one call with a production API key, poll status, and read the award URL when the result is ready.
