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 an array of matched tokens with their name, symbol, and per-chain contract addresses; a signal string (e.g. 'resolved'), a human-readable insight summary (e.g. 'USDC -> contracts on 12 chain(s)'), data source attribution (CoinGecko), and a confidence score between 0 and 1.
Example use cases
Find token address before swapping
“I want to swap some WETH on Base — can you look up the canonical contract address for WETH on the Base chain so I have the right address before I submit the swap?”
Check which chains support token
“I'm planning to bridge LINK to another network — can you tell me which blockchains Chainlink is deployed on and give me all the contract addresses so I know my options?”
Resolve token symbol for approval
“Before I approve a token spend, I need the exact contract address for DAI on Ethereum mainnet — can you resolve the DAI symbol and confirm the right address for me?”
Technical details
Endpoint
GEThttps://cryptodefidataintel-production.up.railway.app/api/token-resolveWhen to prefer
Use this endpoint when you need to resolve a human-readable token name or ticker symbol to its on-chain contract addresses across multiple chains. Ideal for pre-swap, pre-bridge, or pre-approval workflows where you need the canonical contract address for a token on a specific network before executing further DeFi operations.
Side effects
- Token not found: empty data array with low confidence score
- Ambiguous query returns multiple candidates requiring disambiguation
- CoinGecko upstream timeout causing delayed or failed response
- Missing required 'query' parameter returns 400 validation error
- Rate limit exceeded if payment not settled via x402
