## 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 sweetai-should-i-pay-lite-5c1f6854
```

Example prompt: Before I send 5 USDC to agent ID 4821, run a quick should-I-pay check and tell me whether to pay, use caution, or skip — and how much I might lose if I go ahead.

## When to prefer this

Choose this endpoint when you need the cheapest possible pre-payment sanity check on an AI agent and don't need the full on-chain evidence dossier. At $0.002 per call it is 5x cheaper than the full /should-i-pay endpoint, making it ideal for automated pipelines that screen many agents or small payment amounts where a thorough audit would cost more than the payment itself. Prefer it for real-time agentic workflows where speed and cost matter more than forensic depth.

## Known failure modes

- Missing both agent_id and solana_asset — returns error requiring at least one identifier
- Invalid or unrecognized agent_id — may return low-confidence SKIP or error
- Malformed solana_asset pubkey — returns parsing error
- Payment of 0.002 USDC not fulfilled — x402 payment required error before response is served
- Amount_usd not provided — verdict returned without expected loss calculation

## How this service works

Call this before sending money to an unknown agent: Should-I-Pay Lite is the cheapest pre-payment decision — PAY/CAUTION/SKIP + confidence + expected USDC loss for your exact amount. Decision core only; full evidence dossier is in /api/v1/should-i-pay ($0.01). Target by agent_id, solana_asset, seller_url or pay_to. GET or POST with JSON body. No account, no API key

## Output

Returns a three-value decision (PAY / CAUTION / SKIP), a confidence score indicating how certain the verdict is, and an estimated expected USDC loss for the specific amount the caller is about to send. This is a lightweight decision-core response; full on-chain evidence is available from the premium endpoint.
