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 feed address, chain, latest price with decimals, age in seconds since last update, a FRESH/WATCH/STALE status, a human-readable note about update recency, a staleness warning disclaimer, and the timestamp of the check. Does not validate sources, aggregation, or deviation thresholds — heuristic staleness screen only.
Example use cases
Pre-trade oracle staleness check
“Before I swap on this DeFi protocol, check if the Chainlink ETH/USD feed 0x5f4ec3df9cbd43714fe2740f5e3616155c5b8419 on Ethereum is fresh or stale so I know the price data is reliable.”
Cross-chain oracle monitoring on Base
“Is the Chainlink USDC/USD price feed at 0x7e860098f58bbfc8648a4311b374b1d669a2bc9 on Base currently fresh? Tell me the price, decimals, and how old the last update is.”
DeFi liquidation bot oracle validation
“Check the Chainlink BTC/USD feed 0xf4030086522a5beea4388093aea4ba702a71e50 on Arbitrum and flag whether it's FRESH, WATCH, or STALE — I need to know before triggering any liquidation logic.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/oracle-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.10) heuristic check on whether a specific Chainlink price feed has been updated recently before executing a DeFi transaction or liquidation. Prefer this over a full audit tool when you only need staleness/recency validation for a single feed, not source validation or deviation threshold analysis. Ideal for pre-transaction safety checks in automated DeFi agents.
Side effects
- Invalid or non-existent feed contract address returns an error
- Unsupported chain name returns a validation error
- On-chain RPC call failure or timeout returns a connectivity error
- Feed with no recent round data may return STALE with missing price fields
- Malformed 0x address format causes a parse error
