Can Orrery be used as a Polymarket API for AI agents?

Yes. Orrery exposes agent-readable public Polymarket context: search, movers, snapshots, brief previews, MCP, and paid x402 endpoints for derived evidence. It is not a raw market-data redistribution feed.

Why not call raw Polymarket APIs directly?

Raw APIs are useful, but agents often need interpreted evidence: source checks, source health, resolution status, related-market comparison, movement explanation, and a safer next-step envelope.

Does Orrery execute Polymarket trades?

No. Orrery is read-only. It monitors and explains public prediction-market context for research workflows.

Polymarket context API for AI agents

Use Orrery as a derived evidence API for AI agents working with public Polymarket context: movers, market search, snapshots, source health, resolution-risk checks, why-it-moved summaries, MCP, and x402 Evidence Cards.

Direct answer

Use Orrery when an agent needs evidence around Polymarket data, not just raw prices.

Use market search and movers to discover active contracts.

Use resolution-risk and why-it-moved endpoints before an agent cites or escalates a market.

Use Evidence Cards for stable parsing across market, brief, and attention-queue workflows.
