## Data and API

Constella's Identity Intelligence API provides RESTful, real-time access to the world's most curated identity data lake. Unlike raw data brokers, every record passes through a proprietary multi-stage verification pipeline before delivery.

- [Intelligence API](https://constella.ai/data/intelligence-api/): RESTful API delivering verified breach, infostealer, and dark web intelligence. Sub-second latency (<200ms). Supports querying across 70+ unique identity attributes. Built for high-volume, multi-tenant environments.
- [Data Pedigree and Methodology](https://constella.ai/data/data-pedigree-methodology/): Constella's four-phase data lifecycle — multi-vector collection, source authentication, automated deduplication, and entity resolution — that separates verified intelligence from raw noise. Every record traced to a confirmed breach or exposure event.
- [Use Cases (API)](https://constella.ai/data/use-cases-api/): Detailed use case guidance for integrating identity intelligence into fraud decisioning, MDR detection stacks, OSINT platforms, identity theft monitoring products, and ATO prevention workflows.
- [Developer Portal](https://constella.ai/data/developer-portal/): API documentation, authentication, endpoint reference, and integration guides.
- [Partner Inquiry](https://constella.ai/partner-inquiry/): OEM, white-label, and reseller partnership structures for MSSPs, MDR providers, identity platforms, and technology integrators.

**Key data facts:**
- 1 trillion+ attributes indexed across the Surface, Deep, and Dark Web
