# Vangrid ## Docs - [Vangrid API Authentication: Keys and Bearer Tokens](https://docs.vangrid.io/api/authentication.md): All Vangrid API requests require a Bearer token. Learn how to obtain your API key, include it in requests, and handle authentication errors. - [POST /v1/ingest — Data Ingestion API Reference](https://docs.vangrid.io/api/data-ingestion.md): POST /v1/ingest — Submit spatial observations from your sensors into the Vangrid network to enrich ground truth and receive cryptographic provenance records. - [Vangrid Enterprise Spatial API: Overview and Reference](https://docs.vangrid.io/api/overview.md): The Vangrid Enterprise Spatial API provides access to real-time ground truth, spatial queries, data ingestion, and live streaming from the edge network. - [POST /v1/spatial/query — Spatial Queries Reference](https://docs.vangrid.io/api/spatial-queries.md): POST /v1/spatial/query — Query real-time ground truth for a geographic area of interest. Accepts GeoJSON geometry, returns verified spatial observations. - [POST /v1/spatial/stream — Streaming API Reference](https://docs.vangrid.io/api/streaming.md): Subscribe to a real-time JSON stream of ground truth events for a defined area of interest. Receives push updates from the Vangrid edge network. - [Authenticate Requests to the Vangrid API](https://docs.vangrid.io/authentication.md): Secure every Vangrid API request using your API key as a Bearer token. Learn how to obtain credentials, pass them correctly, and handle auth errors. - [Inside Vangrid's Sovereign Spatial Data Pipeline](https://docs.vangrid.io/concepts/data-pipeline.md): Understand how Vangrid moves data from edge nodes through cryptographic signing to your API requests, maintaining sovereignty at every step. - [Edge Nodes: Vangrid's Distributed Sensor Network](https://docs.vangrid.io/concepts/edge-nodes.md): Vangrid's 3B+ edge nodes are the foundation of the spatial network, capturing continuous multi-view data without requiring hardware purchases. - [Ground Truth Data: Verification and Confidence Scores](https://docs.vangrid.io/concepts/ground-truth.md): Ground truth in Vangrid means verified, real-world spatial observations with cryptographic proof — not inferred or synthetic data. - [How Vangrid Works: The Spatial Data Pipeline](https://docs.vangrid.io/concepts/overview.md): Learn how Vangrid's decentralized edge network collects, processes, and delivers verified spatial data to your applications in real time. - [Cryptographic Provenance: Verifying Spatial Data Integrity](https://docs.vangrid.io/data/cryptographic-provenance.md): Every Vangrid observation includes a provenance_hash — cryptographic proof the data came from a real edge node at a specific time and has not been altered. - [Data Sovereignty: Residency and Access Controls](https://docs.vangrid.io/data/data-sovereignty.md): Vangrid's sovereign data pipeline gives enterprise customers control over data residency, access boundaries, and jurisdictional compliance for spatial workloads. - [How Edge-Computed Privacy Works in Vangrid](https://docs.vangrid.io/data/edge-privacy.md): Vangrid processes sensor data at the edge before transmission. Raw streams never leave the source node — your queries return only derived ground truth. - [Vangrid: Real-Time Spatial Intelligence at Scale](https://docs.vangrid.io/introduction.md): Vangrid is a sovereign spatial data platform delivering continuous ground truth from 3B+ edge nodes for autonomous systems and physical AI. - [Quickstart: Make Your First Vangrid API Call](https://docs.vangrid.io/quickstart.md): Learn how to authenticate, query real-time spatial ground truth, and stream live data from the Vangrid Enterprise Spatial API in minutes. - [Autonomous Logistics with Vangrid Spatial Data](https://docs.vangrid.io/use-cases/autonomous-logistics.md): Use Vangrid's real-time ground truth to power last-mile delivery robots, autonomous vehicles, and fleet coordination in dense urban environments. - [Monitoring Critical Infrastructure with Vangrid](https://docs.vangrid.io/use-cases/critical-infrastructure.md): Stream continuous ground truth from Vangrid edge nodes to detect anomalies, track changes, and protect critical infrastructure assets in real time. - [Embodied AI: Continuous Spatial Ground Truth for Robots](https://docs.vangrid.io/use-cases/embodied-ai.md): Vangrid provides the continuous spatial ground truth that embodied AI and robotics systems need to perceive, navigate, and act in the physical world. - [Vangrid for Sovereign Defense: Verified Spatial Intel](https://docs.vangrid.io/use-cases/sovereign-defense.md): Vangrid delivers cryptographically verified ground truth for defense applications requiring nation-state data sovereignty and tamper-evident provenance.
