The data layerfor Trading
Real-time and historical data across 120+ networks, validated at ingestion and delivered through one high-performance API.
- Free public endpoint
- Zero egress fees
- Dedicated enterprise infrastructure

Exchanges, protocols and research desks route billions in value through decisions made on onchain data. bZerpha verifies every block before it reaches them, so a missed reorg or a dropped log never becomes a mispriced trade.
Measured under production traffic.
Seven days of mirrored production queries against four providers, scored on response correctness and end-to-end latency.

TVL secured by protocols running on bZerpha
Institutional-grade data for systems managing billions.
Liquidation engines and risk oracles can’t wait for a provider to notice a reorg. Lending protocols use bZerpha as the single source for positions, prices and events — validated before their keepers ever act on it.

Every block passes through ingestion, six independent validation checks and replication before it is served — in roughly the time a single RPC call takes elsewhere.

The complete data stack
Four integrated products for production-grade data infrastructure. Use one, or run the whole stack.
Enterprise‑grade by default
The guarantees large teams ask for in procurement are part of the base product — not an upsell.
Dedicated gateway
Your own isolated API infrastructure with configurable networks, rate limits and a contractual SLA.
Genesis to head
Historical and real-time data from a single interface. No separate archive service, no stitching.
One API across chains
The same query model across EVM and non-EVM networks, with consistent field names and types.
Validated at ingestion
Multiple independent correctness checks run before any block enters the pipeline.
No vendor lock-in
Open architecture and open-source SDK. Self-host the full stack whenever you need to.
Verifiable audit trail
Query responses are signed by the worker that served them and attributable end to end.
Agents need data they can trust.
Autonomous systems should not stitch together five unreliable providers. Give them one validated data layer.

user › What were the five largest WETH swaps on Base in the last hour?
tool › bzerpha.get_swaps({ chain: "base", token: "WETH", window: "1h", sort: "amount", limit: 5 })
agent › The largest was 412.8 WETH → 1.31M USDC in block 20,500,113. All five results are validated and signed; sources attached.▍
Open data, zero friction
A free public endpoint agents can call without keys or onboarding.
Pre-built agent skills
MCP server and tool schemas for balances, swaps, transfers and more.
Validated inputs
Every response is checked before an agent can reason or act on it.
Full lifecycle automation
Agents can spin up, query and tear down their own indexers.
Open architecture
Typed OpenAPI spec and open-source SDK. Nothing hidden behind a model.
Production tested
Already serving millions of tool calls a day for live agents.
