OverBlock Documentation

OverBlock provides blockchain data as a service for teams that need reliable access to on-chain data — starting with production live APIs.

The platform is built around a simple idea:
you focus on how to use the data, while we handle infrastructure, indexing, and scaling.

What OverBlock provides​

Live APIs​

Real-time and near-real-time blockchain data delivered via HTTP APIs and WebSockets.

How it works:

  • Enable a live API app in the dashboard
  • Get a token
  • Call REST endpoints or subscribe via WebSockets
  • Monitor usage and billing per app

→ See: Live APIs

Historical APIs (coming soon)​

Access indexed historical blockchain data through app APIs — built for fast backfills, investigations, and compliance.

Planned coverage includes:

  • Blocks and transactions
  • Balances and address-level data
  • High-throughput streaming for large historical ranges

We will expand networks based on user demand.

Analytics Datasets (coming soon)​

Download ready-to-use blockchain datasets for analytics, reporting, and research — delivered as versioned releases.

Examples of dataset types:

  • Raw exports (blocks / transactions / balances)
  • Analytics-ready packs (wallet clusters, transfer flows, interaction graphs)

Delivery options:

  • Downloadable exports (CSV/Parquet/SQL)
  • Delivery to your S3 bucket
  • Warehouse-friendly formats and snapshots

Managed Indexers (coming soon)​

Deploy dedicated parser/indexer pipelines per project — fully managed by OverBlock.

How it works:

  • You define a custom data model (JavaScript/TypeScript) using our framework
  • We deploy and operate the pipelines (hosting, scaling, monitoring, chain specifics)
  • You consume the resulting data via API, streams, or exports

This is a fit when you need a custom data product, when a ready-made live app doesn’t exist yet, or when you run high-load workloads.

How it works​

  1. Create an application in the dashboard
  2. Enable a product app (Live APIs today, more soon)
  3. Generate an API token
  4. Integrate using HTTP or WebSocket APIs
  5. Monitor usage and billing in the dashboard

Authentication & access​

All products use token-based authentication.

  • Tokens are managed in the dashboard
  • Tokens are scoped per application
  • Usage and limits are tracked per app

Authentication details and examples are provided in each product section.
