## 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-escrow-lane-5a3ca26a
```

Example prompt: Create an escrow deal for 1.5 USDC on Base with seller wallet 0xAbC...123, label it 'logo design job', and give me the sign-ready calldata — set the timeout to 48 hours.

## When to prefer this

Use this endpoint when an AI agent needs to trustlessly lock USDC on Base mainnet for a peer-to-peer or agent-to-agent work transaction, without a custodian holding the funds. Prefer this over direct wallet transfers when you want a timeout-based refund guarantee and a non-custodial release mechanism. Best for agent pipelines that need sign-ready calldata rather than executing the transaction themselves.

## Known failure modes

- Missing required 'action' query param returns error
- action=status without job_id returns error
- Invalid seller wallet address format causes failure
- amount_usd not parseable as a number causes failure
- timeout_hours outside 1–720 range may be rejected
- Contract not audited — on-chain failures possible on Base mainnet
- Render.com cold-start latency may cause timeouts on first call

## 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 job_id, the escrow contract address on Base mainnet (0x6b290f88b49eC73d954f05423a7F17020C5fDB70), sign-ready approve and create calldata for action=create, or the current on-chain escrow state for action=status, along with a plain-English summary, the fee in USDC, and the amount escrowed.
