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 containing the token symbol, a list of per-chain prices with deviation in basis points relative to the median, the maximum spread in bps across all chains, the median price, a plain-English arbitrage signal (e.g. 'spread within 30 bps — likely noise after bridging costs'), and a note clarifying that bridging fees, latency, and slippage are not subtracted from the gross spread.
Example use cases
Spot arb opportunity before bridging
“I'm thinking about bridging USDC to grab a cross-chain spread — can you check the price of USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum and tell me the spread in bps across chains and whether it looks like a real arb or just noise?”
DeFi bot pre-trade spread check
“Before my bot executes a cross-chain trade on WBTC, check the contract 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Ethereum for cross-chain price deviations — I need the per-chain prices and the max spread in basis points.”
Research token price consistency
“I want to know if this new token at 0x4d224452801ACEd8B2F0aebE155379bb5D594381 on Ethereum is priced consistently across chains or if there are suspicious deviations — give me the cross-chain spread analysis.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/dex-arb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, keyless cross-chain price comparison for a specific token to assess DEX arbitrage feasibility. It is ideal for pre-trade checks by DeFi bots or agents before committing to a bridge transaction. Prefer this over generic price feeds when you specifically need multi-chain deviation in basis points and a built-in arb signal. Not suitable when you need net profit estimates after bridging fees or real-time slippage-adjusted quotes.
Side effects
- Missing required query params 'chain' or 'address' returns a 400-level error
- Invalid or non-existent token contract address returns empty or error response
- Chain name not recognized causes lookup failure
- DeFiLlama price data unavailable for token results in no quotes
- Payment of $0.05 USDC not provided triggers x402 payment required response
