Comparison

Orrery vs EventGraph

Orrery is not trying to out-EventGraph EventGraph. It wins a different job: turning prediction-market movement into source-aware, settlement-aware, agent-readable evidence.

Where EventGraph is strong

Developer-facing Polymarket data surface with portfolio, wallet, market, order-book, event, and discovery endpoints.

Developer-friendly endpoint breadth
Portfolio and wallet API positioning
Order-book and market data hooks
Useful fit for builders who want raw Polymarket coverage

Where Orrery differs

Orrery deliberately avoids copy-trading, “AI alpha”, and smart-money claims. The product is built around source quality, derived market state, resolution risk, daily workflow, alerts, and agent-safe JSON.

Orrery returns source-aware Decision Cards, not only raw endpoint objects
The free starter API helps agents discover markets before paid intelligence calls
Resolution risk, source extraction, and next-call hints are built into the API story
Public pages and Markdown variants make citations easier for agent answers

Recommended Orrery path

research only

Use Orrery when an agent needs interpreted market context and a next verification step, not only raw Polymarket data.
