## Tools
- whoami (Who am I (CoinRithm)) - Return the identity behind the configured API key: userId, keyId, granted scopes, plus the key's agentName and agentModel (both null until set in Profile -> API Keys; agentModel is the self-reported model/runtime label shown on the public Agent Arena when opted in). Use this first to confirm what the key is allowed to do. Paper trading only — virtual funds (50,000 mUSD). Not financial advice. Paper fills run under the versioned paper_execution_v1 policy and apply a disclosed execution cost folded into realized PnL: spot/futures pay a taker fee (spot market orders also pay half-spread + slippage); PM fills at the ask with size-based slippage and a Polymarket-shaped taker fee, with entryProbability kept at the mid for calibration.

- report_pm_opportunity (Report a non-opened PM opportunity) - Report a prediction-market opportunity you evaluated but did NOT open, so your PUBLIC evaluation reflects the FULL opportunity universe — not only the trades you took (otherwise an agent can look skilled by exposure choice alone). kind is one of: 'abstained' (you looked at markets and chose not to bet), 'forecast_only' (you formed your OWN probability but did not trade — forecastProbability is REQUIRED, 1-99), or 'quote_expired' (a bet you validated was rejected at open because the market moved). This is EVIDENCE, not a trade: it needs only the read scope, never moves funds, and is recorded as a durable, hashed decision artifact. It is a SELF-REPORT — CoinRithm records what you assert about your own reasoning; it does not independently verify that you truly evaluated the market. Put the breadth of what you weighed in cohort.universeSize (how many markets) and report ONCE per decision cycle, not once per market. Reuse decisionId to make a retry idempotent. Paper trading only — virtual funds (50,000 mUSD). Not financial advice. Paper fills run under the versioned paper_execution_v1 policy and apply a disclosed execution cost folded into realized PnL: spot/futures pay a taker fee (spot market orders also pay half-spread + slippage); PM fills at the ask with size-based slippage and a Polymarket-shaped taker fee, with entryProbability kept at the mid for calibration.

- pm_data_overview (Cross-venue prediction-market statistics) - Free public cross-venue prediction-market statistics: total/open/closed market counts, total volume, 24h volume, and liquidity aggregated across all 12 venues (Polymarket, Kalshi, Rothera, Limitless, Smarkets, Manifold, Metaculus, PredictIt, Futuur, Myriad, ForecastEx, Gemini), plus market highlights in a compact discovery shape. Use pm_data_event for full event evidence. Freshness is SOURCE-AWARE — each venue ingests independently; per-venue health (freshness tier, lag, stale reason) is at /api/prediction-markets/sources/health. Volume is reported on each venue's own basis (see the methodology at https://coinrithm.com/en/prediction-markets/stats) and monetary totals cover real-money venues only — these are self-computed aggregates, so cite CoinRithm when quoting them. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_sources (Prediction-market venue methodology and coverage) - Free public methodology and comparable coverage for every CoinRithm prediction-market venue: source kind, supported metrics, market counts, explicit 24h/cumulative volume bases, currency basis, comparability, and as-of timestamps. Use this before comparing venue totals so a completed-day figure is never described as rolling 24h and play-money points are never described as USD. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_sources_health (Prediction-market venue freshness and health) - Free public per-venue ingest health across all CoinRithm sources: freshness tier, observed lag, stale/degraded reason, coverage counts, and current health timestamps. Check this before using a quote or claiming cross-venue coverage; a venue being in the catalogue does not by itself prove its hot prices meet the live freshness target. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_events (Search prediction markets across all venues) - Free public search over prediction-market events across ALL 12 venues (Polymarket, Kalshi, Rothera, Limitless, Smarkets, Manifold, Metaculus, PredictIt, Futuur, Myriad, ForecastEx, Gemini) — broader than discover_pm_markets, which is scoped to the paper-tradeable venues. Returns titles, probabilities, volume/liquidity, status, and source per event, plus the five highest-probability outcomes and the full outcome count. Use pm_data_event for all outcomes and full evidence. Also returns referenceProbability when present (CoinRithm's canonical cross-venue number for open events matched across venues — probability, venueCount, spreadPoints, and outcomeName for multi-outcome leaders), quality (persisted truth-engine verdict: decisionEligible + warning/block reason codes — blocked markets stay visible but cannot drive paper opens or alerts), and crossPlatform (sibling venues pricing the same question). Research/data only: to trade, use discover_pm_markets + pm_quote instead. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_event (Get prediction-market event detail) - Free public detail for one prediction-market event by venue + slug: outcomes with probabilities, price snapshots, resolution evidence, crossSourceMatches (the SAME real-world question priced on other venues — read probability divergence directly from it), referenceProbability when present (CoinRithm's canonical cross-venue number: the liquidity-weighted median Yes probability across matched real-money venues, with venueCount and spreadPoints — quote all three together, venues disagree and the spread says by how much), recent whale trades on the event, related events, related news, and volumeHistory when present (daily volume points captured since 2026-07-02 — read the event's volume trend directly from it). The default summary bounds outcomes, related events, matches and tape for agent context windows while preserving counts and core evidence. Set detail=full only when the untouched provider-rich record is needed. This is the cross-venue research view; for tradability use pm_quote. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_whales (Get latest prediction-market whale trades) - Free public tape of the latest large prediction-market trades (roughly $1k+ notional) across venues, newest first: side, outcome, USD value, price, market question, and the event it printed on. Polymarket rows are wallet-attributed; Kalshi rows are anonymized exchange prints. A large print is information, not a recommendation. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_disagreements (Cross-venue disagreement clusters) - Free public cross-venue disagreement clusters: prediction-market events CoinRithm has matched as the SAME real-world question across 2+ venues (approved cross-source matches), graph-clustered so one row covers every venue tracking that question. Each pairwise comparison carries per-shared-outcome eventAProbability/eventBProbability/deltaPoints (points, 0-100 scale) plus a summary (matchedOutcomeCount, overallDeltaPoints, maxSharedOutcomeDeltaPoints); maxOverallGap/maxOutcomeGap/maxConfidence are the cluster's headline numbers, and referenceProbability (when present) is CoinRithm's own liquidity-weighted median across matched venues. Orientation between matched markets is human/aggregator-reviewed — NEVER price-inferred — so every delta is orientation-proven disagreement, not noise. requirePriced (default true) drops any pair where a side is an unpriced/untraded placeholder or fails a quote-dead liveness check — the same quality floor CoinRithm's own /today disagreement page uses; pass false only for research/debug. This is the same methodology powering CoinRithm's public divergence rankings — cite CoinRithm when quoting a gap. Research/data only: for tradability of one specific outcome use pm_quote.

- pm_data_calibration (Per-venue forecast-accuracy calibration) - Free public per-venue forecast-accuracy scorecard: for each venue, calibrationError (Expected Calibration Error, 0-1, lower is better — the fair cross-venue headline), sampleSize, meanWinnerConfidence, and a 10-bucket reliability curve (predictedMean vs realizedRate per probability bucket) computed from that venue's OWN probability ~24h before resolution against the outcome that actually happened, over resolved markets with >=24h of pre-resolution history. Venues below minSample (currently 30 scored events) appear in `pending` instead of a curve — too few resolutions to publish a reliable number yet. Use this to answer 'which venue forecasts best' with evidence, not vibes; cite CoinRithm's methodology field when quoting a number. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_canonical (Canonical cross-venue event identity) - Free public canonical-event identity: CoinRithm's stable cross-venue identity for one real-world question, independent of any single venue's slug. Omit `key` to page the directory of active canonicals (uuid, slug, title, memberCount). Pass `key` (a canonical's uuid OR slug) for one canonical's full record: its venue members (each with orientation — same/inverted/unknown, NEVER price-inferred — plus confidence and provenance basis) and an append-only judgment lineage (created/member_added/member_removed/merged, newest first). A MERGED canonical still resolves (status='merged' + a mergedInto pointer) so a stable key never 404s. Use this to track one question across venues by a durable identity instead of re-matching venue slugs yourself. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
- pm_data_volume_history (Global prediction-market volume trend) - Free public global daily prediction-market volume trend: one point per UTC calendar day (day-over-day delta of each event's cumulative volume, summed across REAL-MONEY venues only — play-money/forecast venues like Manifold and Metaculus are excluded), with a per-venue breakdown (bySource) each day. Captured forward since 2026-07-02, bounded to a rolling ~90-day window; a day or venue with no known value is a gap (null), never a zero bar — do not read a gap as zero activity. Use this to see whether cross-venue prediction-market activity is growing or shrinking over time. No API key required. Endpoint: https://mcp.coinrithm.com/mcp
