## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability trollbridge-preflight-token-safety-bundle-47b7d73f
```

Example prompt: Before my agent buys into this token, run a full preflight safety inspection on contract address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base — check for honeypot, rug-pull risk, and contract safety, and also include the approval screen for my wallet 0xAbCd1234... so I know if it's cleared for takeoff.

## When to prefer this

Choose this endpoint when you need a single bundled pre-transaction safety call covering honeypot, rug-pull, and contract risk in one request at $0.05 USDC, rather than calling each check individually. It is ideal for AI agents that need a fast go/no-go verdict before executing a token trade or approval. Use it over individual check endpoints when you want a combined overall verdict with minimal latency and cost overhead.

## Known failure modes

- Missing required 'address' query parameter returns an error
- Invalid contract address format (non-0x) may return an error or empty results
- Unsupported chain value returns validation error
- Contract not found on specified chain returns null or unknown verdict
- Payment of $0.05 USDC not provided results in HTTP 402 payment required
- Rate limiting or service unavailability on onrender.com free tier

## 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 response containing individual check results (honeypot verdict, rug-pull score, contract risk level), an optional wallet approval screen, an overall verdict string (e.g. 'cleared for takeoff', 'proceed with caution', or 'do not touch'), a summary description, and the riskiest finding identified — all for the queried token contract address.
