MISO
MISO Market User Interface (MUI) 2.0 API

The closed counterpart to everything else in this profile — MISO's programmatic JSON web API for registered market participants to submit energy supply offers and demand bids, query submissions, and query day-ahead and real-time market results as they clear. MISO documents it publicly in the MUI 2.0 API User Guide, which states verbatim that "All market participants using the JSON programmatic interface must be registered with MISO" and gives the base URL as https://markets.midwestiso.org/dart2 for production and https://cce.midwestiso.org/dart2 for the customer-facing test environment. Access is gated by a client digital certificate issued through the MISO Market Portal: an anonymous TLS connection to markets.midwestiso.org on 2026-07-27 failed at the handshake with an SSL alert rather than returning any HTTP status, which is direct evidence of mutual-TLS client-certificate enforcement. No OpenAPI is published and none could be harvested; the guide PDF is the only contract.
