• polymarket_all_markets read-only

  Paid data plan required. Return every active Polymarket market across all categories, not only crypto. AI execution credits do not unlock this export. The text result is one LLM-readable line per market: MARKET_NAME | OUTCOME PRICES | DEADLINE | MARKET_ID. The sweep fails closed if complete pagination cannot be verified and includes timestamp, count, source-page count, and SHA-256.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• polymarket_search_markets read-only

  List Polymarket up/down crypto prediction markets for a coin. Returns market id, slug, window, status and timing. Use the returned id/slug with polymarket_get_market or polymarket_get_snapshots.

  Parameters:

  • coin — string — Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only.
  • type — string — Filter by market window/type, e.g. 5m, 15m, 1h, 4h, 24h.
  • limit — integer — Page size (1–100).
  • cursor — string — Opaque pagination cursor from a previous response's pagination.next_cursor.
  • end_time — string — Filter: markets active at/before this time as ms-epoch or ISO-8601. History is clamped to your plan's window.
  • resolved — boolean — true → only resolved markets, false → only active.
  • start_time — string — Filter: markets active at/after this time as ms-epoch or ISO-8601. History is clamped to your plan's window.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• polymarket_get_market read-only

  Fetch a single Polymarket market by id (market_id) or by slug. Provide exactly one of market_id or slug.

  Parameters:

  • coin — string — Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only.
  • slug — string — Market slug (alternative to market_id).
  • market_id — string — Market id from polymarket_search_markets.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• polymarket_get_snapshots read-only

  Historical order-book snapshots (time series) for one Polymarket market. Use interval to downsample and include_orderbook for the full ladder. History depth is gated by plan.

  Parameters:

  • market_id (required) — string — Market id from polymarket_search_markets.
  • coin — string — Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only.
  • fill — string — ffill returns ONE ROW PER BUCKET for the whole window, carrying the last captured book into buckets that held no capture. Each row then carries `filled` (0 = a capture, 1 = carried forward) and `as_of_ts`, the moment that book was recorded. Requires `interval`. Without it, `interval` returns only the buckets that held a capture — a short series means the market is quoted infrequently, not that data is missing.
  • limit — integer — Page size (1–1000).
  • cursor — string — Opaque pagination cursor from a previous response's pagination.next_cursor.
  • end_time — string — End of time as ms-epoch or ISO-8601. History is clamped to your plan's window.
  • interval — string — Downsample bucket — 30s, 1m, 5m, 1h, up to 1d. Returns the newest book in each bucket. Omit for every recorded book change.
  • start_time — string — Start of time as ms-epoch or ISO-8601. History is clamped to your plan's window.
  • include_orderbook — boolean — Include the full bid/ask ladder per snapshot (default top-of-book).

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• kalshi_get_candles read-only

  Hourly OHLC candles (yes bid, yes ask, traded price) plus volume and open interest for a Kalshi market. This is the only history that exists for non-crypto Kalshi markets — Kalshi serves no historical order book — and it reaches back up to a year, far past the order-book capture. `price` is null in periods with no trade. Every account plan; history is bounded by your plan window.

  Parameters:

  • ticker (required) — string — Exact Kalshi market ticker from kalshi_search_markets (never constructed from a timestamp).
  • limit — integer — Page size (1–500).
  • cursor — string — Opaque pagination cursor from a previous response's pagination.next_cursor.
  • end_time — string — End of time as ms-epoch or ISO-8601. History is clamped to your plan's window.

  Historical L2 depth snapshots (time series) for a Limitless market by slug. Every account plan; history is bounded by your plan window.

  Parameters:

  • slug (required) — string — Limitless market slug.
  • fill — string — ffill returns ONE ROW PER BUCKET for the whole window, carrying the last captured book into buckets that held no capture. Each row then carries `filled` (0 = a capture, 1 = carried forward) and `as_of_ts`, the moment that book was recorded. Requires `interval`. Without it, `interval` returns only the buckets that held a capture — a short series means the market is quoted infrequently, not that data is missing.

• bars read-only

  OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each both a US ETF and a Binance pair, and resolve to the equity — pass venue=binance to reach the pair instead. Optional `venue` selects the market explicitly: us-equities, binance (spot) or binance-futures (perpetuals). Bounded by the same plan history window as every other read (403 HISTORY_LIMIT_EXCEEDED past it); the plan also sets how many symbols one request may carry.

  Parameters:

  • symbols (required) — string — Comma-separated symbols, e.g. "AAPL,BTCUSDT,BTCUSDT.P". 3 per request on Explorer, 8 Quant, 16 Research, 32 Desk.
  • end_time — string — End of time as ms-epoch or ISO-8601. History is clamped to your plan's window.
  • timeframe — string — 1Min (default), 5Min, 15Min, 1Hour or 1Day.
  • start_time — string — Start of time as ms-epoch or ISO-8601. History is clamped to your plan's window.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• backtest_paths read-only

  Mid-price path per Polymarket market for backtesting, resampled to a fixed interval and bounded to each market's own lifetime so post-settlement books cannot leak in as risk-free fills. Returns {interval_seconds, markets:{<market_id>:{points:[[ts_ms, price_up, coin_price], …]}}} — up to 1000 points per market. Pass 1 to 50 market ids from polymarket_search_markets. History is bounded by the plan window and the interval floor by plan; both fail closed rather than silently coarsening.

  Parameters:

  • ids (required) — string — Comma-separated Polymarket market ids, 1 to 50, from polymarket_search_markets.
  • coin — string — Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only.
  • interval — integer — Resample interval in seconds (default 60). The floor is set by plan; a finer value is refused, not rounded.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• screener read-only

  Cross-venue top-of-book snapshot for all assets across Polymarket, Kalshi, and Binance — a one-shot overview of the current state. No arguments.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• whoami read-only

  Show the current session's plan, rate limits, history window, and coin access (reflects keyless demo vs. your API key).

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes
