Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability apollo-web3-hackathon-aggregator-ebeb418a
```

Example prompt: What Ethereum hackathons are currently open for registration? Pull the latest list from Apollo's Web3 hackathon feed and filter by the Ethereum chain.

## When to prefer this

Use this endpoint when an AI agent needs to discover currently open Web3/blockchain hackathons across major chains. Prefer this over general web search when you need structured, deduplicated, machine-readable hackathon data with registration status confirmed. Especially useful for developer agents looking to participate in or track upcoming crypto competitions without scraping multiple platforms like ETHGlobal or Colosseum manually.

## Known failure modes

- Invalid chain filter value returns an error or empty results
- No hackathons currently open for registration returns an empty hackathons array
- Service temporarily unavailable during data refresh cycle
- Payment failure (402) if USDC payment not properly submitted
- Stale data if last_scan is older than expected 4h refresh window

## How this service works

Web3/blockchain hackathon aggregator — only relevant events with open registration. Refreshed every 4h.

## Output

A JSON object containing a list of hackathons with open registration, each including name, blockchain chain, registration deadline, prize pool amount, platform (e.g. ETHGlobal, Colosseum), and a direct link. Also includes metadata: total count, data sources, and last scan timestamp. Data is refreshed every 4 hours.
