Prediction market intelligence for AI agents

Edge Point signals

Start here: what Signal itself thinks is worth attention, and why — one call instead of a search, a history and an edge lookup.

get_signal_board

The ranked board of markets worth a look now: a 0–100 score with its parts, Kalshi price against fair value, the Polymarket gap and the scenario behind it.

get_fair_value

Signal’s fair probability for one market against its Kalshi price, and how many standard deviations apart they are.

get_market_scenario

Why a market is moving: its scenario, severity and the news headlines attached to it, with its board score and fair value.

get_market_summary

Price, 24-hour change, volume, open interest and volatility for one market — the cheapest “where is it and how did it move” call.

get_news_signals

Recent sports news and social headlines Signal has matched to markets, with source, sentiment and how many markets each touches.

Built to be acted on

• Read-only. No tool places, changes or cancels an order.
• Responses are sized for a model: an over-long result keeps its newest data and says what it left out, instead of being cut mid-way.
• Every response carries its own timestamp (asOf, sampledAt or updatedAt): quote the data’s time, not the call’s.
• Settled and finished markets are flagged, so a settlement price is never mistaken for a live one.
• Rankings state the window and coverage they used.
• Thin markets are flagged as lowLiquidity: a large move on little volume is noise.
• A missing value is reported as missing, never filled in as zero.

Read this before acting

• An edge is a gap between venues, not a guaranteed profit. It can close against you.
• Fees, the bid/ask spread and available liquidity can erase an edge smaller than a few points.
• A benchmark priced by only one or two sources is weak evidence; Signal withholds its mispricing score in that case.
• The API and MCP tools are read-only: they never place an order or move funds. Nothing Signal returns is financial advice.
