How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
A list of cross-chain bridge protocols matching the query, including bridge names and volume data, filtered by the specified chain and sorted by the requested order (volume or name), up to the specified limit.
Example use cases
Finding bridges for a specific chain
“Which cross-chain bridges support Ethereum? Give me the top 15 sorted by volume.”
Researching bridge options alphabetically
“List all the DeFi bridges you know about sorted by name, up to 50 results.”
Comparing bridge volume on Base
“What are the highest-volume bridges that work on Base network? Show me the top 5.”

Endpoint
POSThttps://chat.sperax.io/api/x402/tools/bridges/getBridges?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, up-to-date list of DeFi bridge protocols filtered by blockchain network and ranked by volume or name. Prefer this over general web search when you need machine-readable bridge data for DeFi routing, research, or agent-driven cross-chain planning. It requires no API key and charges only $0.001 USDC per call via x402.
Side effects
- Invalid chain name returns empty list or error
- Unsupported sortBy value rejected with validation error
- Payment failure via x402 protocol results in 402 response
- Limit exceeding service maximum may be capped or rejected
- Network timeout if Sperax backend is unavailable
