How this service works
On-chain intelligence for AI agents. 70+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

A JSON response indicating the best available yield (APY/rate) for the specified asset, including the protocol name, chain, and yield percentage, allowing an agent to recommend or act on the top opportunity
Example use cases
Finding best stablecoin yield
“Where can I earn the highest APY on my USDC across DeFi protocols right now?”
Optimizing ETH lending returns
“Which on-chain protocol is currently paying the best yield for ETH deposits?”
Comparing SOL staking and lending APY
“What's the best yield available for SOL across all supported chains and protocols?”
Technical details
Endpoint
GEThttps://ragdar.vercel.app/api/yields/best/%7Basset%7DWhen to prefer
Use this endpoint when an agent needs to quickly surface the single best yield opportunity for a specific crypto asset across multiple chains (Base, Arbitrum, Solana) without manually querying multiple protocols. Prefer this over general DeFi aggregators when you need on-chain intelligence with micropayment access via x402 and coverage specifically across these three ecosystems.
Side effects
- Unknown or unsupported asset symbol returns an error or empty result
- Asset not available on any supported chain returns no yield data
- Network or RPC issues may cause stale or unavailable data
- Invalid asset path parameter format may return a 400 or error response
- x402 payment failure prevents access to the endpoint
