## 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 agent-pay-gate-809a5ec8
```

Example prompt: Before I send $500 USDC to 0x1a2b3c4d5e6f7890abcdef1234567890abcdef12, run an Agent Pay Gate screen on that address so I know if it's safe — flag any sanctions hits, contract-vs-wallet issues, or fresh-address red flags.

## When to prefer this

Use this endpoint when an AI agent is about to execute a USDC payment and needs a real-time, amount-aware compliance verdict before sending. It is purpose-built for agentic payment flows where you want a single authoritative GO/REVIEW/STOP signal combining OFAC sanctions, Basename/Coinbase identity, contract-vs-wallet detection, and fresh-address heuristics — rather than assembling those checks yourself from multiple sources.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Missing required 'to' parameter returns a 400-level error
- Upstream sanctions or identity data temporarily unavailable may delay or degrade response
- Address is valid but has no on-chain history — may result in STOP for any material amount
- Rate limiting or payment failure (x402) blocks the call

## How this service works

A pre-payment gate for an agent about to send USDC. Screens the recipient (OFAC sanctions, Coinbase/Basename identity, wallet vs contract, fresh-address age) and escalates a fresh or anonymous recipient to STOP once the amount is material — a few cents to a new address is sampling, real size to one is the drain to avoid. Pass usd= for amount-aware guidance. One verdict (GO/REVIEW/STOP). Identity is not intent; not financial advice.

## Output

A single verdict string — GO, REVIEW, or STOP — along with supporting signals: OFAC sanctions match status, Coinbase/Basename identity presence, whether the address is a smart contract or EOA, and fresh-address age assessment. When a USD amount is provided, the verdict is sharpened based on materiality (small amounts to unknown addresses may pass where large ones would STOP).
