How this service works
SCRIPTMASTERLABS x402 Gateway. Discover paid APIs and inspect fresh x402 v2 payment requirements before calling them. Current hosted authority is USDC on Base mainnet (eip155:8453); caller controls spending policy. MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.
Output
A JSON object containing a snapshot of current MEV relay activity, including transaction ordering data, relay pulse metrics, and possibly block builder statistics. The response schema is open-ended (example: {}) suggesting the output structure varies by relay and activity.
Example use cases
Real-time MEV relay monitoring
“Check the MEV pulse right now and give me the top 5 entries from the relay so I can see if there's unusual transaction ordering activity.”
DeFi bot competitive analysis
“Fetch the current MEV pulse from relay https://boost-relay.flashbots.net and return up to 20 results so I can analyze what block builders are active.”
MEV opportunity scanning
“Query the MEV pulse endpoint with a limit of 50 and tell me if there are any significant extraction opportunities showing up in the relay data right now.”
Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/mev-pulse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time MEV relay pulse data and are willing to pay $0.02 USDC per call via x402 on Base mainnet. Prefer this over free alternatives when you need fresh, low-latency relay data with no API key registration. Best suited for DeFi agents, MEV bots, or block-builder monitoring workflows that require on-demand relay snapshots.
Side effects
- 402 Payment Required if x402 payment not attached and no valid X-Api-Market-Key or X-API-Key provided
- relay_url not reachable or returns no data — empty or error JSON response
- limit parameter out of range — may return default number of results or error
- relay data unavailable during low-activity periods — sparse or null payload
- network timeout if the relay URL is slow to respond
- invalid relay_url format — likely a 4xx or descriptive error JSON
