What Oddsight is for

"What are the odds?" has a market answer now. Oddsight puts three venues side by side — Kalshi, Polymarket and Manifold — so an assistant can say what the crowd currently pays for an outcome, on which market, at what volume, resolving on exactly which wording, and how that has moved. It never places a bet and never gives its own prediction.

Venues

• Kalshi — CFTC-regulated designated contract market in the U.S.; dollars; public trade API. Oddsight uses Kalshi's own search for relevance, then reads each event's markets and prices (bid/ask midpoint, else last).
• Polymarket — the largest prediction market, settled in USDC on Polygon; not offered to U.S. persons. Oddsight uses the public Gamma API for search, prices and rules and the CLOB API for history.
• Manifold — a play-money forecasting community; useful as a crowd forecast where no real-money market exists, flagged play_money and excluded from the consensus when a real-money market matches.

How the consensus works

probability takes the best-matching open market on each venue (relevance by shared words, with names and numbers required — "100k" and "$100,000" are treated as the same number), drops venues whose best match is a clearly different question, and reports a volume-weighted consensus plus the spread between venues. A spread over ten points is flagged: it usually means the questions differ in date or threshold, or one market is thin. Thin markets (low volume and liquidity) are flagged individually.

What the numbers mean

A probability here is the price of the Yes side in cents on the dollar: what traders are paying, including risk premium, fees and the cost of locked capital until resolution. It is a crowd estimate, not a calibrated forecast. Always read market_detail for the rules before quoting a market whose wording matters.

Tools

Ask the crowd

probability — One question, every venue: the best-matching market on each venue with its implied probability, a volume-weighted consensus, the spread between venues (divergence), thin-market flags, and each market's exact wording so differences in the question are visible. Use for "what are the odds of X", "how likely is Y", "what does the market say about Z". Args: question, venues.

search_markets — Find open markets about a topic across Kalshi, Polymarket and Manifold: each with the venue, the exact question and outcome, the implied probability, bid/ask where available, volume, liquidity, close date and link, ranked by relevance then volume. Use for "what markets are there on X", "find the Fed meeting market", "is anyone trading on Y". Args: query, venues, limit.

market_detail — Everything about one market: the exact question and rules, resolution source and close/settlement dates, current bid/ask and last price, volume, liquidity and open interest, all outcomes for multi-outcome markets, and the link. Read this before quoting a market whose wording matters. Use for "what exactly does this market resolve on", "when does it settle". Args: venue, market_id.

price_history — How a market's probability moved over a window: start, end, high and low with times, the biggest single move, and a compact series. Use for "how has this moved this week", "when did the odds flip", "was it ever above 80%". Args: venue, market_id, days.

What's moving

resolving_soon — Markets that close within the window, biggest by volume first, with their current probability — what the world is about to find out. Use for "what resolves this week", "anything big settling this weekend". Args: days, limit.

trending — The most-traded markets right now by 24-hour volume (Polymarket) and the most popular on Manifold, with probabilities — a read on what the crowd is arguing about. Use for "what's hot in prediction markets", "what are people betting on". Args: limit.

Maths & venues

odds_math — Convert between an implied probability, American odds and decimal odds, and — given the person's own estimate — the edge and expected value per dollar. Pure maths, no market data. Use for "what's 62 cents as odds", "-150 as a probability", "if I think it's 70% and the market says 55%, what's my edge". Args: probability_pct, american_odds, decimal_odds, your_probability_pct.

venues — Who the venues are — regulation, who may trade, settlement currency, fees, how resolution works — so the person can judge a price and their own eligibility. Use for "is Polymarket legal for me", "what is Kalshi", "is Manifold real money".

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Oddsight — Privacy Policy

Effective 22 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Oddsight is. Oddsight is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for prediction-market information: search, probabilities across venues, market rules, price history, what resolves soon, trending markets and odds maths. You interact with your assistant; the assistant sends us only the specific request needed: a question or topic in words, a market identifier, or numbers for the odds calculator.

What we receive. The arguments of each tool call, the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

What we do not receive or store. We do not receive your conversation with the assistant, your name, contacts, or credentials for any service. Request arguments (a question, a topic, a market) are used to fetch the answer in memory and are not stored. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Your own estimates. A probability estimate you give to the odds calculator is used for that computation only and never stored. Oddsight has no accounts on any venue and never asks for venue credentials.

Sub-processors. To answer requests we send only the question, topic or market asked about (never anything about you) to Kalshi (U.S.), Polymarket (Gamma/CLOB public APIs) and Manifold Markets (U.S.). Hosting: Vercel (United States regions).

Legal bases and your rights. For users in California, the EU/UK and elsewhere, our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Oddsight is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Oddsight — Terms of Service

Effective 22 September 2026. These terms govern use of the Oddsight connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Oddsight returns prediction-market information from Kalshi, Polymarket and Manifold: market search, probabilities across venues, market rules, price history, what resolves soon, trending markets and odds arithmetic. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Not advice; not a venue. Market prices are crowd estimates and can be wrong, thin or manipulated; nothing here is a prediction or a recommendation to trade. Each venue's rules govern resolution. Eligibility to trade depends on your jurisdiction (Polymarket is not offered to U.S. persons; Kalshi is a U.S.-regulated exchange); you are responsible for complying with local law. Unify Dynamics LLC is not a broker, exchange or adviser.
3. Odds maths. Expected-value and Kelly figures are arithmetic on the estimate you supply; they say nothing about whether that estimate is right, and fees, spreads and capital lock-up reduce any edge.
4. Acceptable use. Do not use the Service to overwhelm the underlying services or to circumvent rate limits. Automated use within the published limits is welcome.
5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
6. Data. Our Privacy Policy describes what we process. In short: nothing about you is stored.
7. Attribution. Market data is published by Kalshi, Polymarket and Manifold under their own terms; respect those terms when reusing output.
8. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
9. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss arising from use of or reliance on the Service. Our total liability is limited to US $100.
10. Governing law. California law; venue in San Mateo County, California.
11. Contact. Unify Dynamics LLC · agent@connectorbay.com · https://connectorbay.com/oddsight
