## Real-Time (WSS)

Real-time delivery over **WebSockets (WSS)** is priced **flat** — not CU-based. WSS is available on a **custom plan**; pricing starts at **\$1,500/month** based on chains, datasets, and connection requirements. Low-latency delivery is a core strength of BlockDB, supported efficiently via WebSockets (WSS) including **Protobuf**.

## Bulk Export (SFTP, S3, Azure & more)

Full historical data is available both through the API (CU-based) and via direct bulk delivery. For large backfills or ongoing dataset syncs, **bulk delivery is significantly cheaper than querying through the API** — you pay for the dataset and delivery method, not per-row CU costs.

Pricing is **customized for each customer**.

### Pricing Factors

* **Datasets**: Which datasets you need (blocks, transactions, logs, pricing, etc.)
* **Chains**: Number of blockchain networks (Ethereum, Polygon, Arbitrum, Base, etc.)
* **Delivery Method**: SFTP, S3, Azure Blob Storage, Snowflake Share, Redshift Share, BigQuery, or Databricks Delta Share
* **Delivery Frequency**: One-time export, daily, weekly, or monthly snapshots
* **Data Volume**: Historical depth and time range requirements

<Callout icon="lightbulb" color="#3B82F6" iconType="regular">
  Each bulk delivery configuration is unique. We work with you to design a solution that matches your data requirements, budget, and infrastructure preferences.
</Callout>

### Request a Quote

Email [support@blockdb.io](mailto:support@blockdb.io) with your dataset and delivery requirements. We'll respond with a custom quote, typically within 1-2 business days.
