OpenAPI Specification

openapi: 3.2.0
info:
  title: SiftingIO Market Data Crypto 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.
