  title: Astreus API
  version: 1.0.0
  description: >-
    Astreus is a financial data terminal that turns the world's unstructured
    financial disclosure into structured, traceable data. It reads what
    companies, exchanges and central banks publish — annual and interim reports,
    SEC filings, results announcements, investor presentations, earnings calls,
    8-Ks, regulator notices and policy text — across the United States, the Gulf
    (Tadawul, DFM, ADX, Boursa Kuwait, QSE), Japan, Taiwan, Korea, the UK and
    Europe, and serves it as data a program can trust: standardized financial
    statements (annual, quarterly, semiannual), segments and KPIs, the tables
    inside the notes, filing sections as text, investor decks page by page,
    earnings-call transcripts and audio, span-anchored observations, management
    guidance scored against outcomes, typed 8-K events, an attributed intraday
    news tape, insider and 13F ownership, a people registry, point-in-time macro
    series and central-bank text, benchmark, commodity and compute-price series,
    and a validated causal claim graph with scenario simulation. Every number
    carries the filing, page or passage it came from (`fact-source`), and
    nothing is served until it passes per-company validation gates.


    Coverage is published live: `GET /api/v1/landing/coverage` (no key) returns
    every market served with company counts, history depth, completeness and
    periods held per data type — ask it before answering "what do you cover?".
    `{id}` is a ticker, a numeric SEC CIK, or a platform key for a non-SEC
    issuer (XSAU000001) — the `cik` field of the company payload. Human-readable
    guides: https://doc.astreus.ai (coverage at /coverage, data catalog at
    /data-catalog).


    Tiers: `public` endpoints need no credentials. Everything else takes an
    **API key** — create one on the Developers page in the terminal
    (https://astreus.ai/developers) and send it as `X-API-KEY: pk_live_...` (or
    `Authorization: Bearer pk_live_...`). Signed-in terminal sessions may use
    their Cognito ID token instead.


    Rate limits and quotas are per plan (fixed UTC windows): Free — 30 req/min,
    250 req/day; Build — 300 req/min, 100,000 req/month; Scale — custom. Build,
    Scale and prepaid credits are set up with sales
    (https://astreus.ai/contact), not self-serve. Responses carry RateLimit-*,
    X-Quota-* and, when credits pay, X-Billing-Source/X-Credits-Remaining-USD
    headers; a 429 carries `Retry-After` and a machine `code` of rate_limited or
    quota_exceeded (with sales_email).
