Trader decision layer

Discover the market.
Inspect the evidence.
Decide with execution context.

Pro turns the infrastructure into a WHY NOW decision workspace; Desk adds verified executable edge, size, costs and EventCap Certified gates.

01

Protect the downside before sizing

Loss Guard combines spread, liquidity, concentration, close-time and public-position context so weak entries can be rejected earlier.

02

Detect momentum that deserves review

Market Activity Radar and Momentum prioritize fast probability moves, volume acceleration and large observed flow instead of forcing you to scan raw feeds.

03

Turn evidence into a decision brief

Execution Quality Triage, rule evidence, track-record context and explicit unavailable states keep Watch, Review and Avoid decisions evidence-bound.

PM × Kalshi verification

Compare equivalent contracts.
Keep rule differences visible.

Supporting research checks event, outcome, line, timing and settlement terms before a cross-market comparison is shown. Executable edge additionally requires fresh synchronized books, fees, spread and slippage.

Event Intelligence Infrastructure

Five evidence layers.
One verified intelligence system.

Built on the same read-only market, rule and execution evidence used inside EventCap. Every layer keeps uncertainty, missing evidence and verification boundaries explicit.

01 · CORE GRAPH/api/v1/event-graph

Universal Event Graph

Organizes venue-specific contracts around stable EventCap event identities. Human-verified relationships can connect equivalent contracts; unmatched markets remain standalone.

Canonical event IDsVenue rolesSource freshnessVerified edges only
02 · RULE LAYER/api/v1/resolution-intelligence

Resolution Intelligence

Returns settlement clauses, rule differences, certification state, missing evidence and rule-change risk. Ambiguity blocks certification instead of being guessed away.

FAIL CLOSEDMissing clauses stay missing.
03 · EXECUTION LAYER/api/v1/executable-pricing

Executable Pricing

Moves beyond last price into spread, depth, fees, slippage, fillable size and synchronized quote evidence before net execution claims are surfaced.

EVIDENCE GATEDNo complete inputs, no manufactured edge.
04 · EXPOSURE LAYER/api/v1/institutional-risk

Institutional Exposure Discovery

Maps explicit business exposure terms to relevant event-market indicators for monitoring and research. Relevance is not corporate loss severity, and market probability is not a company loss forecast.

RELEVANCE ONLYYour exposure model stays yours.
05 · AGENT LAYER/api/v1/agent-brief

Agent Decision Brief

Packages event identity, resolution evidence, pricing context and decision signals into a structured brief that software agents can read, analyze, rank and recommend for human review.

NO TRADE WRITE ROUTERead · analyze · recommend only.
Developer API

Build on the decision layer.

Pro includes account-owned scoped API keys, usage controls and IP allowlist contracts; Desk adds executable cross-venue intelligence.

Why the infrastructure matters

Market data tells you the quote.
Event intelligence explains the decision boundary.

EventCap connects identity, rules, freshness, risk and execution evidence before a cross-market or machine-readable conclusion is allowed to look certain.

FAQ · Prediction markets in 60 seconds

Understand the market.
Know exactly what Pro changes.

Start with the basics, then see why price alone is not enough for a decision.

Prediction markets in 60 seconds

A market turns a real-world question into a priced YES / NO contract.

A 63¢ YES price means the market is trading YES at $0.63. People often read that as roughly 63% market-implied probability, but it is still a market price — not a guarantee.

01QuestionWill event X happen?
02Market priceYES = 63¢
03ResolutionYES settles at $1, NO at $0

The settlement rule decides the outcome. EventCap organizes the evidence around that decision; it does not guarantee the result.

01
Start hereThe concepts a first-time user should understand
What exactly is EventCap?

EventCap is read-only prediction-market intelligence. It brings official market data, risk, activity, execution context and verified cross-market research into one workflow so you spend less time reconciling separate screens and more time reviewing the evidence behind a decision.

What does a prediction-market price such as 63¢ actually mean?

It means a YES contract is currently priced at $0.63. That price is commonly interpreted as roughly 63% market-implied probability, but it can move and it is not a forecast guarantee. The contract's settlement rule still determines whether YES ultimately pays $1 or $0.

Why look at both Polymarket and Kalshi?

Two venues can reflect different participants, liquidity, order books and contract wording. Seeing both can reveal disagreement or execution differences, but EventCap only treats a cross-market comparison as decision-grade when the underlying contracts and settlement terms are actually equivalent.

Does EventCap place trades, hold funds or control my account?

No. EventCap is a read-only research product. It does not expose order, cancellation, withdrawal or transfer actions. You remain responsible for any action you choose to take on an external venue.

What changed with Event Intelligence Infrastructure?

EventCap now exposes the same verified evidence model through five read-only infrastructure APIs: Universal Event Graph, Resolution Intelligence, Executable Pricing, Institutional Exposure Discovery and Agent Decision Brief. This expands EventCap from a trader workspace into an intelligence layer that applications, research teams and AI agents can consume.

Can an AI agent automatically trade through EventCap?

No. The Agent Decision Brief is read/analyze/recommend only. This release deliberately exposes no automatic trade-write route; execution remains a separate external boundary.

02
Why Pro or Desk?What changes when you move beyond simply watching prices
What is the real difference between Free, Pro and Desk?

Free tells you what is moving. Founding adds lifetime core WHY NOW intelligence, momentum, replay, wallet-flow and cross-market research. Pro adds full sizing, scanner, private sync, exports and higher limits. Desk adds verified executable edge, size, fees, slippage, resolution equivalence and EventCap Certified gates.

If Polymarket and Kalshi prices differ, is that automatically profit?

No. A headline gap can disappear after contract-rule differences, bid/ask spread, fees, available depth, slippage or stale quotes are considered. EventCap intentionally separates raw disagreement from an executable opportunity instead of presenting every price gap as money you can capture.

What makes an opportunity “executable” in EventCap?

The pair must be verified as the same contract outcome, both sides need sufficiently current market data, and the calculation must account for spread, available size, fees and slippage. If required evidence is missing, EventCap keeps the state unavailable rather than manufacturing an execution signal.

Couldn't I do all of this manually?

Yes. The value of Pro is not that the underlying information is impossible to find. It is that repeatedly checking market identity, rules, freshness, risk, spread, depth, fees and cross-market context across many markets takes time. EventCap compresses that repetitive research into one consistent workflow.

When Pro starts to matterYou already know the price. Now you want to know whether the evidence supports acting on it.

Use Pro for WHY NOW. Use Desk when you need verified executable economics.

03
Before you buyData, verification, limits and purchase terms
Where does EventCap market data come from?

Supported prices, order books, trades, market history and rules are sourced from official Polymarket and Kalshi interfaces used by EventCap. Runtime synthetic market data is not substituted when official evidence is unavailable.

How are Polymarket and Kalshi markets verified as the same market?

Automated discovery can propose candidates, but a decision-grade comparison requires the event, outcome, threshold or line, timing and settlement terms to align for that specific pair. Rule differences remain visible instead of being silently treated as equivalent.

What happens when data is stale, sparse or incomplete?

EventCap keeps the limitation visible. Stale quotes remain labeled, sparse official history does not become a synthetic chart, and missing execution inputs do not become a confident recommendation. A trustworthy “unavailable” state is more useful than false precision.

Does EventCap guarantee profitable trades or accurate outcomes?

No. EventCap is research software, not a profit guarantee, exchange, broker or financial adviser. Markets can move, liquidity can disappear and outcomes can resolve unexpectedly. Pro is designed to improve the quality and speed of your research, not remove risk.

What does “Founding Member · 99 USDC once” mean?

It is the Founding Member offer: 99 USDC one-time for lifetime core intelligence, limited to the first 1,000 members. Standard Pro is 99 USDC per 30-day access period and Desk is 999 USDC per 30-day access period, renewed manually through Solana Pay.
