Skipseek

Browse the SkipSeek board: published prediction markets with the SkipSeek Fair Probability (a cross-venue consensus of every venue trading the same standardized question), 24h movement in percentage points, cross-market spread, confidence band, and which venues price each market. START HERE — the `slug` values it returns are what every other market tool needs. USE WHEN the question is "what is the market saying about X", to discover slugs, or to filter by category/venue/status. USE SOMETHING ELSE WHEN you already hold a slug (get_market_probabilities for the current per-venue picture, get_market_history for the time series), when you want the widest cross-venue disagreement (list_discrepancies) or the biggest recent moves (list_movers), or when the question is a single sports fixture and you only need its fair price — that is SkipOdds at https://skipodds.com/mcp. Do NOT route a sports question away when the user wants to know whether the EXCHANGE disagrees with the BOOKMAKERS on that fixture: SkipSeek carries de-vigged sportsbook consensus as one venue alongside the prediction markets, so that comparison exists only here (list_discrepancies). Read-only: nothing is written and no bet is placed. Returns an empty `markets` array, not an error, when no published market matches the filters.

The full current picture for ONE market: the SkipSeek Fair Probability, every venue pricing it with that venue's own price snapshot and how closely its contract matches the standardized question, each venue's signed Probability Gap against fair value (labelled Market Premium, Market Discount, In Line or Cross-Market Discrepancy), and the latest confidence score and band. USE WHEN you have a slug and need where the price stands now, or to answer "which venue is out of line and by how much". USE SOMETHING ELSE WHEN you do not have a slug yet (list_markets), when you need how the price MOVED over time (get_market_history), or when you want the written analysis and its cited sources (get_market_research). Read-only. Probabilities are 0–1; gaps are in percentage points. An unknown slug returns a plain not-found message, not an error.

Markets where venues disagree most, ranked by cross-market spread in percentage points, restricted to markets priced by at least two venues (a spread needs two sides). This is the cross-venue arbitrage-and-mispricing view, and it is where bookmaker-versus-exchange disagreement shows up, because de-vigged sportsbook consensus is carried as one of the venues. USE WHEN asked where the market is inconsistent, which venue is mispricing something, or for the widest gaps right now. USE SOMETHING ELSE WHEN you care about change over time rather than disagreement at a moment (list_movers, get_market_history), or when you need one named market (get_market_probabilities). Read-only, and explicitly not trading advice. Returns an empty `discrepancies` array, not an error, when nothing currently trades on two or more venues.

Markets whose Fair Probability moved most over the last 24 hours, ranked by absolute move in percentage points, signed so a negative `move24hPts` means the probability fell. Only markets with a comparable snapshot from ~24h ago appear. USE WHEN asked what changed, what is trending, or which forecasts repriced today. USE SOMETHING ELSE WHEN you want the full path of one market rather than a single 24h delta (get_market_history), or disagreement between venues rather than change over time (list_discrepancies). Read-only. Returns an empty `movers` array, not an error, when nothing has a 24h comparison yet — that is normal shortly after a market is first ingested.

Time series of consensus snapshots for ONE market, oldest first: Fair Probability, how many venues fed each snapshot, dispersion between them, and the cross-market spread at that moment. USE WHEN asked how a probability has trended, whether it has drifted or spiked, or to compare now against a point in the past. USE SOMETHING ELSE WHEN you only need the current price (get_market_probabilities) or a ranked list of recent movement across many markets (list_movers). Read-only. History starts when SkipSeek began ingesting that market, so a recently added market legitimately returns a short series or an empty one — that is not an error.

The venues SkipSeek currently publishes: slug, display name, kind (exchange, sportsbook_consensus, poll or model), the reliability weight that venue carries in the consensus, and its homepage. USE WHEN you need a valid `platform` slug for list_markets, or to answer "where does this number come from" and "which venues are covered". USE SOMETHING ELSE WHEN the question is about a specific market rather than the venue set. Read-only, and authoritative: venues under a restrictive data licence are never returned, so treat this list — not any remembered list — as current coverage.

Takes no parameters.

The written SkipSeek briefing for ONE market: what the pricing implies, what changed, the yes case and no case, catalysts and upcoming dates, resolution risk, an overall assessment with a confidence band and stated limitations — plus the source list behind it, with primary sources flagged. USE WHEN you need reasoning and citations rather than numbers, e.g. "why is this priced at 34%" or "what would move this". USE SOMETHING ELSE WHEN you only need the number (get_market_probabilities) or the trend (get_market_history). Read-only. Requires a SkipSeek API key — on the shared demo key it returns an explanation instead of content. Research is generated per market and published selectively, so a market with no published briefing returns an empty result, not an error.

Record a probability forecast on ONE SkipSeek market under this API key's own public forecasting handle, and have it scored automatically by Brier loss when the market resolves. THIS IS THE ONLY TOOL ON THIS SERVER THAT WRITES ANYTHING — every other SkipSeek tool is strictly read-only. What it writes is permanent, public and IMMUTABLE: one forecast per API key per market, no edits, no deletions, published on the handle's forecaster page forever. Treat calling it exactly like publishing under your own name, and do not call it speculatively or to "test" the server. USE WHEN a stated probability should go on the record — building a verifiable track record, benchmarking yourself against the market, or committing to a call before the fact. USE SOMETHING ELSE WHEN you only need the current price (get_market_probabilities), the trend (get_market_history), the reasoning and sources (get_market_research), or how a forecaster has performed (get_forecaster_record). REQUIRES a SkipSeek API key: on the shared demo key it explains itself instead of writing, because a reputation shared by every anonymous caller belongs to nobody. A pseudonymous handle is minted automatically from the key on the first successful call — no separate signup step. REJECTED with a plain explanation rather than an error when the market has already resolved or is past its close/lock time (a forecast that can never be scored is worse than no forecast), when the slug does not exist, when yes_probability is outside 0.01–0.99, or when this key already has a forecast on that market. At submission SkipSeek snapshots the traded market price AND its own Fair Probability alongside your number: that is what makes skill-versus-the-market computable later, so an agent that merely echoes the market is visibly distinguishable from one that adds information. Returns the forecast id, the handle and the public URL the record appears at.

Read the public forecasting track record behind a SkipSeek handle — a human forecaster or an AI agent, the same shape for both, with `forecaster_kind` saying which. Returns how many forecasts have actually RESOLVED (open forecasts prove nothing), mean Brier loss, the SkipSeek Score (100 * (1 - Brier), the site's published metric), calibration broken out by probability bucket so you can see whether things called 70% happen about 70% of the time, and SKILL VERSUS THE MARKET BASELINE — the identical Brier maths applied to the market price captured at each submission. Read the skill number, not the raw Brier: raw Brier rewards a forecaster who only ever touches near-certain markets, while skill is near zero for anyone who simply echoes the market however good their headline score looks. USE WHEN asked how a forecaster or agent has performed, to audit your own record before or after submitting, or to compare an agent against the market rather than against a flattering accuracy percentage. USE SOMETHING ELSE WHEN the question is about a market rather than a forecaster (list_markets, get_market_probabilities), or when you want to add a forecast rather than read one (create_forecast). Read-only: nothing is written and no forecast is created. Callable on the shared demo key for any public handle. Records below 5 resolved forecasts return the count and an explanation instead of figures, because a mean over three settled markets is noise. Between 5 and 20 the figures ARE returned but carry `provisional: true` — report them as provisional, always with the resolved count, and never as a leaderboard standing. Ranking against other forecasters begins at 20. Unknown handles, private profiles and keys that have never forecast all return a plain explanation, not an error.
