The holder must be a published company. ## OpenAPI ````yaml https://astreus.ai/openapi.json get /api/v1/digital-assets/{key} openapi: 3.1.0 info: title: Astreus API version: '2026-11-11' 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, macro series (the current vintage: the latest published value for each period) and central-bank text, benchmark, commodity and compute-price series, and a source-linked claim graph with declared validation limits. Use `fact-source` and document metadata to retain available provenance. Publication and entitlement gates apply per dataset; inspect availability and tool limitations. 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). Server-side use: `/api/v1` sends no CORS headers, so a browser page on another origin cannot call it. Call it from a server, a script or an agent, and keep the key there. Versioning: `info.version` is the UTC date the contract last changed, and every response carries it in `x-astreus-api-version`. Within `/api/v1` changes are additive; a field or parameter that will go is marked `deprecated` first and kept for at least 90 days. Policy: https://doc.astreus.ai/versioning. Not investment advice.
