Real-time options data API

Real-Time Options Data API for live chain views and market-aware tools

CuteMarkets provides a real-time options data API for developers building live dashboards, scanners, alerting systems, and option-aware trading tools.

Quick answer

A real-time options data API should return the current option surface with enough context to decide whether a contract is usable now. CuteMarkets provides live or delayed chain snapshots, single-contract snapshots, Greeks, IV, open interest, latest quote/trade context, and listed expiration discovery by plan.

Why teams use it

What matters in a real time options data API

Live chain snapshots

Pull complete chain views with latest quote and trade context instead of stitching many single-contract calls.

Greeks and IV in the response

Read Delta, Gamma, Theta, Vega, implied volatility, and open interest alongside pricing context.

Latest contract detail

Query one contract snapshot when you need a focused real-time view of a single strike or leg.

Expiration lookup

Populate expiry pickers and validate listed expiration dates before requesting chain data.

Trading-system friendly responses

Use a consistent JSON surface for scanners, alerting rules, watchlists, and UI widgets.

Immediate path to docs and key creation

Move from the landing page to the API docs and a free API key in a few clicks.

  -H "Authorization: Bearer YOUR_API_KEY"

Why chain snapshots alone are not enough

Real-time options data is not just one price field. Most live products need the whole surface: snapshots, contract detail, expirations, and enough context to decide whether the contract is worth showing or monitoring.
