How this service works
Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.
Output
A JSON array of active prediction markets, each containing a natural-language question (e.g. 'Fed rate cut in September?'), total trading volume in USD, and an array of outcome prices representing probabilities for each possible outcome. Also returns the count of markets returned.
Example use cases
Fed rate cut probability check
“What's the current market-implied probability of a Fed rate cut in September, and how much volume is being traded on that question?”
Macro event sentiment dashboard
“Pull up all active prediction markets right now and show me the top questions by trading volume along with their outcome odds.”
Financial event monitoring
“I want to track the current sentiment on upcoming economic events — can you get me the latest prediction market questions and their probability splits?”

Endpoint
GEThttps://api.signalnodus.ai/v1/markets/prediction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro financial events (e.g. Fed decisions, rate changes) and want quantified market sentiment rather than news or analyst opinions. Prefer this over news APIs when you need probability distributions and trading volume as a signal of conviction. Note: the name and sibling endpoints suggest SEC filing diff analysis may be the primary brand offering, so evaluate whether prediction market data is a secondary or experimental feature.
Side effects
- API returns empty markets array if no active markets exist at query time
- Payment failure (402) if USDC micropayment not properly attached via x402 protocol
- Rate limiting or authentication errors if x402 payment header is malformed
- Stale or delayed data if market prices have not refreshed recently
