```

Example prompt: Can you get me the full list of decentralized exchanges and their metadata available on the Ethereum chain using the RelAI DEX list?

## When to prefer this

Use this endpoint when you need a curated, up-to-date list of DEXes for a specific blockchain — especially useful for DeFi routing agents, swap aggregators, or applications that need to enumerate available exchange protocols on a given chain. Prefer this over manual curation or static lists when freshness and metadata completeness matter.

## Known failure modes

- Invalid or unsupported chain identifier returns empty list or error
- Payment not fulfilled results in 402 response
- Unrecognized chain path parameter causes 400 or 404 error
- Network timeout or relay service unavailability returns 5xx error

## How this service works

Fetches a curated list of decentralized exchanges and their metadata for the specified blockchain (chain path parameter).

## Output

A curated list of decentralized exchanges (DEXes) supported on the specified blockchain, including metadata such as exchange names, protocol details, and other relevant attributes for each DEX on that chain.
