U.S. stocks & options
market data API.
Build backtests, scanners, and trading dashboards with structured JSON, quote-aware history, listed option contracts, and authenticated WebSocket streams. Built by traders for developer workflows that need reproducible market data.
German precision & billing
CuteMarkets is headquartered and engineered in Germany. The product is built around explicit data contracts, status visibility, and repeatable checks for stock and options market workflows.
For B2B customers, our European entity supports German billing formats and EU tax invoices, including VAT and reverse-charge handling where applicable.

Core market data APIs
Developer surfaces for stocks, options, and backtests
Start with the main product overviews. They describe the data model, request flow, and evidence needed for contract selection, historical research, live monitoring, and reproducible backtests.
Options data API
Contracts, chains, snapshots, trades, quotes, Greeks, IV, and open interest.
Historical options data
Backtest with historical chains, contract records, aggregates, quotes, and trades.
Options chain API
Request listed chains after selecting an underlying, expiration, and filters.
Options backtesting API
Build quote-aware contract selection and execution checks into research loops.
Stocks data API
Snapshots, trades, quotes, aggregates, movers, indicators, and ticker reference.
Market state, more than prices
Options workflows need contracts, quotes, trades, bars, and timestamps in one explainable path
CuteMarkets is organized around the evidence a developer needs before a scanner alert, dashboard row, backtest fill, or paper-trading decision can be trusted. Start from the Options Data API, combine it with the Stocks Data API when the underlying signal matters, then move into docs, tools, and research articles for implementation detail.
Terminology
The words the API keeps separate
Price, quote, trade, chain, contract, snapshot, aggregate, and indicator are different objects. The product pages link into the docs so those boundaries stay visible.
Listed contract universe
Use expirations and contracts before selecting an option leg.
Contracts docs
Chain snapshot
Use chains to inspect strikes, calls, puts, Greeks, IV, OI, latest quote, and latest trade context.
Option chain docs
Quote window
Use bid/ask quotes, spread percent, and quote age before trusting fill assumptions.
Quotes docs
Trade tape
Use prints for activity validation and tape review, not as a universal fill proxy.
Trades docs
Stock context
Use stock snapshots, trades, quotes, aggregates, indicators, and reference data before the option handoff.
Join workflow
Replay artifact
Store the selected contract, request windows, quotes, trades, rejects, and plan labels for auditability.
Replay runbook
Evaluate the platform
Practical due diligence before wiring an API key into production
These entry points keep the homepage focused on product evaluation: coverage, examples, pricing, tooling, and implementation documentation.
Data catalog
Browse stocks, options, reference, snapshot, quote, trade, aggregate, and WebSocket endpoints.
API documentation
Inspect auth, response shapes, request parameters, examples, and endpoint behavior.
Pricing
Compare free, developer, expert, and commercial plans for stocks and options products.
Developer tools
Use calculators, decoders, scanners, and realism checks before automating workflows.
Expiration calendar
Check the next OpEx date, weekly cycles, LEAPS anchors, and ticker-level expiration workflow.
OCC decoder
Parse OCC/OSI symbols into root, expiration, type, and strike before contract requests.
Backtest realism checker
Audit contract selection, spread handling, quote evidence, and execution assumptions.
Provider comparison
Compare API coverage and workflow fit with a factual buyer checklist.
Status
Check platform availability and operational status before production integration.
Trust and evaluation evidence
Evaluate the data source, entitlement model, docs, status, and provider fit before committing
Evaluate CuteMarkets with operational material that is available before signup: pricing, live versus delayed data, OPRA/source context, REST and WebSocket access methods, timestamp and session semantics, missing-data handling, commercial-use review, provider comparison, and support.
Source and OPRA context
Understand OPRA-originating options data, quotes versus trades, participant context, and the limits of "one clean price."
Live and delayed entitlements
Separate live, delayed, historical, quote access, WebSocket access, and plan-specific behavior before shipping.
OpenAPI specification
Download the OpenAPI 3.1 spec and inspect response envelopes, pagination, request parameters, and endpoint groups.
Access methods
Compare REST requests, WebSocket streams, historical windows, local caches, backfills, flat files, and pagination.
Ingestion and caching
Plan cache keys, freshness labels, rate-limit budgets, replay manifests, and missing-data reject artifacts.
Timestamps and sessions
Handle UTC, ET, session labels, quote age, completed bars, WebSocket event time, and replay timestamps.
Corrections and missing data
Track empty windows, stale quotes, no-bid options, condition codes, corrected records, and reject reasons.
Commercial-use review
Map live, delayed, quote, display, redistribution, and customer-facing boundaries before production rollout.
Provider evaluation
Use workflow-first provider checks for contracts, chains, quotes, trades, timestamps, entitlements, and missing data.
Stock provider evaluation
Evaluate stock reference, snapshots, movers, trades, quotes, aggregates, indicators, freshness, and stock/options joins.
Status and support
Check platform health, latency, API gateway state, support channels, and production-readiness entry points.
Backtesting built
by traders.
CuteMarkets was founded after years of building and running systematic strategies with the same pain: expensive data, legacy APIs, and too much integration friction. We built the stock and options API we wanted to use ourselves: clean REST, live WebSockets, and production-ready contracts.

Insights & Tutorials
Deep dives on backtesting, stocks and options data, WebSocket patterns, and market microstructure for developers who build.

Options Data API Evaluation Checklist for Developers
Evaluate options data APIs by workflow, contract identity, OPRA/source clarity, quotes, trades, entitlements, timestamps, and missing-data behavior.
