Kalshi provides event-contract market data over REST, WebSocket and FIX. WagerX observed one documented unauthenticated market GET on September 12, 2026: HTTP 200 with a structured markets array and cursor. This is a bounded reachability/shape observation only; it does not verify authenticated streams, accounts, orders or WagerX connectivity. The reviewed official sources did not publish a provider-owned MCP endpoint or A2A Agent Card, so no MCP initialize/tools/list inspection was performed. No provider-owned MCP endpoint or A2A Agent Card was found. Kalshi's Developer Agreement restricts collecting, caching, aggregating and sharing API data without the stated authorization. This terms/data-integration restriction does not prevent an informational source-linked listing; this entry is not an enabled feed or permission to reuse Kalshi data. WagerX did not request credentials or trade.
Evidence & discovery
This profile records public discovery and WagerX observations. It does not establish legality, security, availability or correctness of provider claims.
Protocol observation history
Routine checks collect metadata only: protocol initialization and declared capabilities. Separately authorized read-only tests, where published, are recorded below with their exact inputs and limits.
The profile’s editorial discovery date is preserved above. A structured observation will appear here after a metadata inspection or separately authorized read-only test.
Test results
Separate from protocol observation history. Results record the dated inputs, returned response and stated limits of an authorized read-only test.
Its catalog record may still include discovery and documentation observations. An untested service is not necessarily unavailable.
