How this service works

Blockchain data and intelligence service for AI agents. 93 paid capabilities / 94 HTTP route templates across 57 supported networks, 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-shield?utm_source=zero.xyz

When 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
