Universe totals (companies by sector and exchange, filings by year and type, facts, prices, macro series, transcripts, observations, narratives, guidance commitments, central-bank documents) plus `markets[]`: for every country served, its exchanges, published companies, the earliest reporting period held, the median completeness score, served note tables, and for each data type (financial statements, segments & KPIs, report documents, filing notes, earnings releases, transcripts, audio, investor presentations, 13F holdings) the reporting periods held versus the periods that exist. Ask this before answering "what is your coverage of market X?". ## OpenAPI ````yaml /openapi.json get /api/v1/landing/coverage openapi: 3.1.0 info: 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).
