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.
Example use cases
Compare DEX liquidity across networks
“I'm launching on multiple chains—can you fetch me all the available decentralized exchanges and their details for both Polygon and Arbitrum so I can see where to list my token?”
Build swap routing for new chain
“We just added support for the Optimism network. Can you get the full curated list of DEXes available on Optimism so we can route swaps through the best protocols?”
Audit DeFi protocol availability
“Pull the complete list of decentralized exchanges and metadata for the Base chain—I need to see what swap protocols are actually live there before we deploy our liquidity aggregator.”

Endpoint
POSThttps://api.relai.fi/relay/1772442473781/v4/%7Bchain%7D/dexListWhen to prefer
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.
Side effects
- 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
