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 wallet address, chain, a 'changes' array describing any detected differences in approvals, balances, or exposure since the baseline, a plain-English 'description', a verdict of 'baseline', 'no-changes', or 'changed', and a 'baseline_token' for use in the next call's prev_state parameter.
Example use cases
DeFi wallet safety baseline check
“Set a baseline snapshot for my wallet 0xAbC123... on Base so I can compare it later and see if any new token approvals or balance changes have appeared.”
Post-transaction change detection
“I just did a DeFi swap on Ethereum with wallet 0xDeF456... — compare the current state against my saved baseline and tell me in plain English what changed in my approvals or balances.”
Ongoing agent-driven wallet surveillance
“Keep an eye on my Base wallet 0x789GhI... and every hour check if anything has changed — new approvals, balance drops, or new exposure — and summarize any differences since the last check.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/wallet-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need stateful, incremental monitoring of a specific wallet address — tracking whether approvals, balances, or exposure have changed between two points in time. Ideal for DeFi agents that need to detect rug pulls, unauthorized approvals, or balance drains without re-analyzing the full wallet state every time. Prefer this over one-shot analysis endpoints when you need continuity across multiple agent invocations.
Side effects
- Missing 'wallet' query parameter returns an error
- Invalid or malformed wallet address (not a valid 0x… address) returns an error
- Unsupported chain value returns an error
- Corrupted or invalid base64 prev_state causes diff failure
- Payment of $0.02 USDC not received results in 402 Payment Required
- Wallet with no on-chain history may return empty changes array with 'baseline' verdict
