How this service works
Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.
Output
Returns the recommended bridge protocol (e.g. Across), destination token amount after fees, fee cost in USD, gas cost in USD, estimated execution time in seconds, a human-readable route insight, the data source, and a confidence score between 0 and 1.
Example use cases
Cheapest L2 to L2 bridge
“I want to move 500 USDC from Optimism to Base — what's the cheapest bridge route, and how much will I pay in gas and fees?”
Fast ETH mainnet withdrawal
“I need to bridge 2 ETH from Arbitrum back to Ethereum mainnet as quickly as possible — which protocol should I use and what will it cost me?”
Cross-chain DAI transfer quote
“Can you find me the best route to send 2000 DAI from Polygon to Avalanche, including the total fee in USD and how long the transfer will take?”
Technical details
Endpoint
GEThttps://cryptodefidataintel-production.up.railway.app/api/bridge-quoteWhen to prefer
Use this endpoint when an AI agent needs to programmatically determine the optimal cross-chain bridge route before executing a transfer — especially when cost and speed tradeoffs matter. Prefer this over generic DeFi price feeds when the user specifically wants to move tokens between different blockchains and needs actionable fee and gas estimates. Best for agents building multi-step DeFi workflows that include bridging steps.
Side effects
- No route found between specified chains or token pair — signal may return 'no_route'
- Invalid chain names or token addresses return a 400-level error
- Unsupported token pair on requested chains returns empty or low-confidence result
- fromAmount too small to cover bridge fees may return an error or zero destination amount
- Service unavailable on Railway deployment returns 5xx error
