How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns a shielded routing response indicating that the transaction has been processed through ChainRay's MEV protection layer for the specified chain (e.g., Base), reducing exposure to front-running and sandwich attacks.
Example use cases
Example prompt
“Can you shield my transaction from MEV front-running and sandwich attacks on the Base chain using ChainRay's MEV protection service?”
Technical details
Endpoint
GEThttps://chainray.online/mev-shieldWhen to prefer
Choose this endpoint when an AI agent needs to submit or route a DeFi transaction on Base or other supported chains and wants to protect it from MEV bots (front-runners, sandwich attackers). Ideal for swaps, large trades, or any transaction where value extraction by miners/validators is a concern. Prefer this over unprotected RPC calls when transaction privacy and ordering protection matter.
Side effects
- Unsupported chain specified — only certain chains like Base are supported
- Missing or invalid 'chain' query parameter returns an error or default behavior
- Payment failure (insufficient USDC balance) results in 402 response
- Service unavailable for the requested chain at the time of the call
- Network timeout if the shielding service is under high load
