## Prize Title
**Alethio API Freestyle**
## Challenge Description
Alethio is a comprehensive suite of blockchain exploration and analytics products for the Ethereum network. We've recently launched our [API](https://api.aleth.io/docs) as a direct way for developers to get real-time access to synthesised, indexed on-chain data in a robust and reliable way. Find out more about the capabilities of the API in [this Medium article](https://medium.com/alethio/announcing-the-alethio-api-f5cfd55d8676).
We're on a mission of making Ethereum more transparent and accessible to all, and through our API we're looking to support and accelerate the growth of a new wave of Ethereum-powered tools, products and services.
We want you to build awesome products that provide a useful service to the Ethereum community by making use of the Alethio API to handle enriched, aggregated on-chain data in ways that haven't been possible before.
## Submission Requirements
You are free to pick up any use case, framework or technology (command-line or web-based), as long as you believe the end result can make a fellow Etherean's life a bit easier and your final submission:
1. Makes use of at least *4 different endpoints* of the Alethio API. See a full list of endpoints [here](https://api.aleth.io/docs).
2. Has at least *4 distinct components* or features that display blockchain data in a different way. These can be transaction lists, detail screens, visualizations, interactive query forms, etc.
3. Documents (in a *README file*) how the API endpoints were used for fetching chain data.
We warmly welcome all contributions, but we will only consider your submission eligible for one of the prizes if it meets the 3 criteria listed above.
Here are a few examples to kick off your imagination, but keep in mind that this list is neither authoritative nor exhaustive:
- **A command-line Ethereum explorer**
*Web interfaces are overrated.* Developers spend a lot of their time switching between terminal windows, so having a swiss army knife for reading Ethereum data close to their fingertips will be super useful. This could be a minimalist block explorer, a read-only wallet, a contract/log monitoring tool, etc.
- **An explorer for meta transactions**
*Given a Transaction hash, detect if it's a meta transaction and show its execution details in a user-friendly way*
Useful API features: `Transaction.contractMessages`, `ContractMessage.msgPayload`, `ContractMessage.logEntries`
- **A financial activity feed for a given account**
*Given an account address, display a chronological feed of activities in a user-friendly, readable way*
Useful API features: `Account.etherTransfers`, `Account.tokenTransfers`
- **An DeFi activity dashboard**
*Given an account address, display a timeline of its activity on a DeFi protocol of choice*
Useful API features: `Contract.logEntries`, `Account.transactions`, `Contract.contractMessages`, `LogEntry.eventDecoded`
- **A Layer2 helper tool**
*Easily fetch data that relates to the on-chain anchors, checkpoints or security guarantees of a Layer2 protocol*
Useful API features: `Contract.contractMessages`, `Contract.logEntries`, `Account.transactions`, `Transaction.logEntries`
- **Anything we haven't thought of!**
