CuteMarkets Docs

API Reference

Everything you need to integrate market data, build faster, and scale.

Tip: open /docs/openapi.md directly for raw markdown (easy copy/paste into an LLM).

OpenAPI

The CuteMarkets options and stocks APIs have a published OpenAPI 3.1 specification:

Use it with API clients, code generators, docs tools, or agent frameworks that can ingest OpenAPI.

Authentication

The spec uses a bearer security scheme for API keys:

bash
Authorization: Bearer YOUR_API_KEY

Scope

The specification covers the documented REST market-data surface:

  • option chains and contract snapshots
  • contract reference lookups
  • options trades and quotes
  • stock snapshots, movers, and ticker reference
  • stock trades and quotes
  • aggregate bars, previous-day bars, and open-close snapshots
  • SMA, EMA, MACD, and RSI indicators
  • ticker search and expiration lookup

The WebSocket gateway is documented separately in WebSockets, because OpenAPI does not model the live streaming protocol.

Move from the docs into the product workflow

If you are evaluating the API rather than implementing a specific endpoint right now, the product pages map the live, historical, and chain workflows directly.
