Does Orrery have a prediction market API?

Yes. Orrery exposes free starter endpoints, public OpenAPI docs, MCP, and x402 paid endpoints for prediction-market movement, brief, search, snapshot, resolution-risk, and Decision Card workflows.

What should an AI agent call first?

Agents should start with the free catalog and health routes, then use the Decision API or market-level endpoints when they need structured context with evidence, risks, and suggested next calls.

Is Orrery only a raw Polymarket data API?

No. Orrery uses public Polymarket data, but the product focus is interpreted verification context: status, source, resolution risk, movement explanation, and agent-readable summaries.

Stable JSON context

Orrery prediction market API

Orrery exposes prediction-market data, market movement, Daily Brief context, resolution-risk checks, and Decision Cards through free starter APIs, MCP, and x402 paid endpoints.

Direct answer

Free starter endpoints cover catalog, health, brief preview, movers, search, and snapshot-lite.

Paid x402 endpoints cover deeper explanations, resolution risk, wallet context, share cards, and Decision 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.
