How this service works

The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.

Output

Returns a JSON object with the scanned block count, per-block details (slot, block number, transaction count, gas used, gas limit, extracted ETH value, builder pubkey, proposer fee recipient), aggregate stats (average gas used, total ETH value, distinct builder count), and a plain-English description of the lane.

Example use cases

Monitor MEV builder dominance

“Check the last 30 Flashbots relay payloads and tell me which builders are dominating block production and how much ETH value they're extracting.”

Track gas consumption by MEV bots

“Scan the last 20 MEV relay blocks and give me the average gas used and total ETH extracted — I want to understand how heavy MEV activity is right now.”

Investigate recent block builder patterns

“Give me a breakdown of the last 10 Flashbots builder payloads — builder keys, block numbers, and extracted value — so I can spot any unusual concentration.”

Technical details

Endpoint

GEThttps://mini-tollbooth.onrender.com/mev-scan?utm_source=zero.xyz

When to prefer

Use this endpoint when you need real-time insight into Flashbots MEV builder activity, want to monitor block-level extraction patterns, or need to assess current MEV pressure on Ethereum. Prefer this over generic blockchain explorers when you specifically want builder competition data, relay payload stats, and extracted ETH value aggregated across recent blocks in a single call.

Side effects

Invalid limit parameter (outside 1-100 range) returns an error
Flashbots relay API unavailable causes empty or error response
limit defaulting to 20 if not specified may not cover desired range
Payment of $0.05 USDC required per call via x402 protocol; missing payment returns 402
