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
A JSON object with live gas prices per chain (Base in gwei, Ethereum in gwei, Solana in microlamports per compute unit), status of each chain feed, available speed tiers where derivable, and a recommendation for the cheapest chain to transact on.
Example use cases
Cheapest chain for DeFi swap
“Before I execute this DeFi swap, check current gas prices on Base, Ethereum, and Solana and tell me which chain will cost me the least right now.”
Gas spike alert for pending transaction
“I have a transaction ready to submit — what are gas prices looking like on Ethereum and Base right now, and which one is cheaper?”
Multi-chain gas dashboard update
“Pull the latest gas prices across Base, Ethereum, and Solana for me, including any speed tiers, so I can update my dashboard.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, multi-chain gas price comparison across Base, Ethereum, and Solana in a single call at low cost ($0.02 USDC). Ideal for agents making routing decisions about where to submit a transaction, or for dashboards needing live fee data without building direct RPC integrations.
Side effects
- RPC node unavailable for one or more chains — partial results returned with affected chain marked as degraded
- Network timeout from public RPC — stale or missing gas data
- Rate limiting on public RPC endpoints causing delayed response
- Payment not included or insufficient — 402 response requiring $0.02 USDC via x402
