DepthFeed

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.

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.

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.

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.
