Market evidence API

Prediction-market evidence with source, status, and next-step structure.

Orrery's API is built for agents and research teams that need more than raw odds. It packages market movement, resolution risk, source health, watchlist summaries, and suggested next calls into stable JSON envelopes.

Stable JSON context

Orrery market evidence API

Orrery exposes derived prediction-market evidence for AI agents: market movement, source health, Daily Brief context, resolution-risk checks, suggested next calls, and Evidence Cards.

Direct answer

Free starter endpoints cover catalog, health, source-health meta, brief preview, movers, search, and snapshot-lite.
Paid x402 endpoints cover deeper explanations, resolution risk, wallet context, share cards, and Evidence Cards.
MCP and SDK docs help agents call Orrery from Claude Desktop, Cursor, Claude Code, Python, TypeScript, or curl.
Every endpoint keeps the research boundary explicit and avoids trade execution.
