# Oracles: real-time data feeds

#### What it is

Oracles bring real-world data, prices above all, onto the chain. If your product needs to know what an asset is worth right now, for lending, trading, synthetic assets, or liquidations, an oracle is the data layer that tells it. Any verified oracle integration qualifies if your case holds up.

#### What you could build

* A lending protocol using live price feeds for collateral valuation and liquidation triggers
* Synthetic assets tracking real-world prices; prediction markets integrations
* An integration with DEX or trading product with accurate, manipulation-resistant pricing
* Bringing real-world events on chain like weather in certain areas or events
* Combining oracles with identity verification to enable smart contract validation

#### What the pilot expects

Leveraging an oracle means mainnet transactions where your contract actually **consumes your declared feed**. Only fees paid by wallets other than your own count toward your target (Standard §5.2), so your users, not your team, must be the ones transacting. Floors and target guidance for the Oracles category are in the Transaction Integrity Standard (§3.1, §3.3). Whichever provider you choose, name the feed and its on-chain consumption pattern in your proposal.

#### Get building

* [Oracles on Cardano; developers.cardano.org](https://developers.cardano.org/docs/build/integrate/oracles/overview/)
* **Pyth Pro** (in production on Cardano since May 2026): [Cardano developer portal reference](https://developers.cardano.org/docs/developers/curriculum/dapps/oracles/pyth/) · [Cardano x Pyth integration guide](https://docs.pyth.network/price-feeds/pro/integrate-as-consumer/cardano) ·[ Pyth GitHub ](https://github.com/pyth-network/pyth-crosschain/tree/main/lazer/contracts/cardano)· [Free Pyth Pro API keys for Cardano developers](https://intersectmbo.org/news/pyth-pro-on-cardano-subscription-offer)

#### Readiness & constraints

Pyth runs in production on Cardano. The integration pattern: subscribe to the Pyth Pro websocket, include the signed price update in your transaction via a zero-withdrawal from the Pyth withdraw script. For any other oracle provider, readiness varies and the diligence is yours: verify current feed coverage and the on-chain consumption pattern against your use case before you commit your build plan.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.projectcatalyst.io/open-funding/funding-basics/integration-guides/oracles-real-time-data-feeds.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
