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 destination address, lane identifier, transaction type, chain, semantic flags (e.g. 'native-value-transfer'), ETH value, and a plain-English description of what the transaction does — decoding intent from raw calldata without simulation.
Example use cases
Pre-send transaction sanity check
“Before I broadcast this transaction, can you decode this raw hex and tell me in plain English exactly what it's doing — what value is moving and to which address? Here's the hex: 0x02f87a8204d2...”
Identifying unknown transaction calldata
“I got this signed transaction hex from a dApp and I'm not sure what it actually does. Can you decode it and explain what contract it's calling and what parameters it's passing? 0x02f8b282...”
Auditing a transaction before agent execution
“My agent is about to submit this transaction on Base — can you decode the raw tx hex and give me a human-readable summary of what it moves and where before it goes out? Tx: 0x02f901...”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/tx-plain-english?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent or user needs to understand what a raw signed transaction does before broadcasting it — especially useful for pre-flight checks, auditing agent-submitted transactions, or explaining dApp-generated calldata. It is a decoder, not a simulator; prefer it for fast human-readable translation of transaction intent rather than for predicting execution outcomes or gas costs.
Side effects
- Invalid or malformed transaction hex returns an error
- Unsupported chain identifier causes fallback to Base labeling
- Unrecognized contract ABI means calldata cannot be fully decoded, returning partial info
- Truncated or incomplete hex string causes parse failure
- Missing required 'tx' query parameter returns 400
