A price move becomes useful when the evidence around it stays connected. Filter cited events, filings, news links, entities, revisions, and delivery state across stocks and crypto.
A price bar shows what moved.
DataCedar serves source-labeled stock and crypto bars through one regularized API, with the catalog and coverage state required to know what is actually available.
The evidence shows why it moved.
Join market history to SEC filings, company facts, official crypto announcements, public news references, and macro observations without rebuilding incompatible vendor tables.
Replay only what was knowable then.
Known-at filters exclude later filings, revisions, and events. Source links, coverage states, raw hashes, and request manifests keep the historical result inspectable.
Start with the market. Keep the evidence that explains it.
Each response retains source identity, observation time, known-at time, coverage state, and pagination.
Build one request across market data and events.
Choose the market, interval, cutoff, and evidence bundle once. Keep the returned manifest beside the model or backtest.
Open the dataset builderOne market contract
Use the same bar shape, interval vocabulary, pagination, source labels, and coverage states for stocks and crypto while retaining venue-native symbols.
Evidence beside the price
Add filings, fundamentals, official announcements, cited news, and macro observations to the same reproducible request manifest.
History without invented depth
Every response distinguishes catalog coverage from rows actually held, and records gaps rather than silently compressing them away.
See when every record was observed, published, retrieved, revised, and served.
DataCedar preserves raw inputs, normalizes stable tables, measures expected-versus-actual coverage, and returns explicit gaps instead of silently dropping them.
Known-at
Publication, observation, retrieval, revision, and serving times remain distinct.
Gap-aware
Expected-versus-actual coverage is measured per instrument and interval.
Source-labeled
Every normalized record retains the source and acquisition path behind it.
Acquire
Market, filing, event, and macro sources are fetched on schedules designed for each stream.
Preserve
Every provider response lands in immutable object storage before normalization.
Normalize
Our own pipeline maps sources into stable tables and records gaps and revisions.
Serve
REST, SSE, webhooks, WebSocket, and MCP expose the same normalized identities and provenance.
Coverage you can inspect before integrating.
Catalog presence, stored history, current serving state, and plan depth are separate facts. DataCedar exposes each one instead of implying that every instrument has identical history.

Plan freshness describes intelligence-event delivery after DataCedar receives a source record. Market-data cadence, historical depth, and redistribution rights remain dataset-specific and are published in the coverage ledger and API responses.
