title: SiftingIO Market Data Signals API
version: 1.0.0
description: 'REST data-plane for the SiftingIO market data API: live prices,
SEC fundamentals (filings, XBRL financials, ratios, insiders, ownership),
historical OHLCV bars, market calendars, DEX wallet portfolios, and the
US economic calendar.
Authentication is by API key, sent as the `X-API-Key` header (preferred)
or the `api_key` query parameter.
Several endpoints return large payloads and **require** `Accept-Encoding: gzip`
(they respond `406` otherwise): the screener, both financials endpoints,
all historical-bars endpoints, and the market snapshot.
This document describes the data plane only. Account, billing, and auth
(the `/ops/v1` control plane) are out of scope.

summary: Live technical signal
description: 'Current technical-analysis signal for a stock, FX pair, crypto asset, or commodity: a decision-ready summary (strong_sell to strong_buy) with a score from -1 to +1, plus the oscillator and moving-average indicators behind it, each with its value(s) and vote. Indicators still in warmup are omitted, so the vote counts sum to the rows returned. `price.bar_status` is `forming` when a live tick is folded into the current bar, `closed` when the last settled bar is used.

summary: Historical technical-signal series
description: 'The technical-analysis signal as a time series, one point per bar: summary, score, close, and any discrete events (golden_cross, death_cross, macd_cross_up, macd_cross_down) that fired on that bar. Same computation as the live signal, so a historical point is identical to the one that fired live. `t` is the bar-open time in Unix epoch milliseconds, the same as the `/v1/hist/*` bars routes.
