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 a list of matching DeFi protocols with their name, supported chains, TVL in USD, category (e.g. Lending, DEX), a confidence score, an insight summary string, and data sources used (e.g. defillama).
Example use cases
Find top Ethereum DEX protocols
“Search for DEX protocols running on Ethereum and give me the top 5 results with their TVL, supported chains, and category so I can compare them.”
Look up Curve Finance TVL
“Look up Curve Finance and tell me its current TVL, which chains it supports, and what category it falls under.”
Discover cross-chain lending protocols
“Find me cross-chain lending protocols and return the top results with their TVL, chain coverage, and category — I want to see which ones have the broadest multi-chain support.”
Technical details
Endpoint
GEThttps://cryptodefidataintel-production.up.railway.app/api/protocol-searchWhen to prefer
Use this endpoint when an agent needs to identify, classify, or retrieve metadata about a specific DeFi protocol by name or keyword, especially when TVL, chain support, and category are needed. Prefer over generic web search when structured, machine-readable DeFi protocol data with confidence signals is required.
Side effects
- No protocols found matching query — returns empty data array with low confidence
- Query string missing — 400 error
- Payment not provided or invalid — 402 payment required response
- Upstream DefiLlama API unavailable — degraded or error response
