Data infrastructure for AI agents

Let AI agents react to external data — without rebuilding polling for every source.

Entrpy is building a unified data layer and trigger system for agents: one interface to query normalized data or receive an event when something relevant changes.

Private beta is live with signed, retryable crypto-price webhooks for BTC, ETH, SOL, BNB, XRP and DOGE.

How it works

From changing data to agent action.

A small interface replaces the polling loop, state tracking, condition checks, and delivery plumbing your agent would otherwise own.

Describe the signal

Choose a topic, webhook endpoint, and an optional > or < threshold.

Entrpy watches and persists it

Entrpy monitors the source and stores a matching event before attempting delivery.

Your agent receives the event

A structured, signed webhook wakes your application or agent when action is needed.

Product direction

Useful today. Built for a much larger layer.

The private beta proves event-driven delivery in one data category. The broader data layer is the direction—not a claim about what is already live.

Where we're going

The direction

Query

One interface for normalized data

We're building cross-source normalization and aggregation across more providers.

Watch

Conditions that wake agents

Define what matters, then receive an event when the external world matches it.

Connect

More sources, one layer

Bring provider and developer-owned data into agent-facing SDK and MCP workflows after REST feature parity.

Next: delivery history, observability, more providers, and data categories beyond fintech.

Crypto is the first working data category, not the boundary of the product.

Private beta

Build the agent. Let Entrpy watch the world.

Entrpy is in private beta for developers building agents that need to react to changing external data.
