Indicator API Overview - CryptoQuant API

The Indicator API documents the Alpha Library — the indicator set behind the alpha.cryptoquant.com heatmap. Indicators are organized by asset class, and each one is sourced one of three ways depending on the asset.

Indicators by asset class

Asset class	Indicators	Source	Reference
Crypto (Bitcoin)	On-chain valuation & demand, technical, and analyst consensus	Core CryptoQuant Data API (`api.cryptoquant.com`), in-app technical formulas, and `unbias.fyi`	Crypto Indicators
Equities (KRX)	Computed fundamentals from DART filings, prices, and market data	Alpha equities API (`alpha.cryptoquant.com/api/equities`)	KRX Equities

Every indicator is z-scored over a trailing multi-year window before it is colored on the heatmap (green = bull/buy regime, red = bear/sell regime).

Alpha API surface

The Alpha equities indicators are served from a dedicated host:

https://alpha.cryptoquant.com/api

Unlike the core CryptoQuant Data API, these endpoints are productized indicators, not raw source-data feeds.

Endpoint structure

https://alpha.cryptoquant.com/api

├── /equities
│   ├── /{asset}
│   └── /{asset}/{metric}
└── /indicators

Endpoint	Access	Purpose
`GET /api`	Public	Top-level Alpha API catalog
`GET /api/equities`	Public	Equity asset catalog, metric catalog, identifier policy, and data policy
`GET /api/equities/{asset}`	Pro+ API key	All computed indicator series for one KRX equity
`GET /api/equities/{asset}/{metric}`	Pro+ API key	One computed indicator series for one KRX equity
`GET /api/indicators`	Public	Metadata-only Alpha Library indicator catalog (all asset classes)

Bitcoin on-chain indicators are served by the core CryptoQuant Data API (api.cryptoquant.com), not the Alpha host. See Crypto Indicators for the endpoint behind each signal.

Data policy

DART/OpenDART source filing rows are not redistributed. Equity endpoints expose only computed indicators derived from filings, prices, and market data.

Each equity metric is marked with:

{
  "source": "dart-computed",
  "sourcePolicy": "dart-computed",
  "rawRedistribution": false
}

Relationship to API v1 and API v2

API surface	Host	Scope
Core API v1	`api.cryptoquant.com/v1`	Raw on-chain, market, and flow data
Core API v2	`api.cryptoquant.com/v2`	Curated crypto research indicators
Indicator API	`alpha.cryptoquant.com/api`	Alpha product indicators, including KRX equity fundamentals

The response envelope intentionally follows the same status / result pattern used by the core CryptoQuant APIs.
