## 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 sml-verdict-protocol-decide-76749b9c -d '<json body>'
```

Example prompt: Before my trading agent submits that $50k rebalancing order, run it through the SML Verdict five-juror jury — pass the frozen decision capsule with action REQUEST_DECISION and give me back the signed receipt showing whether it's approved.

## When to prefer this

Choose this endpoint when an autonomous agent must produce a legally or operationally defensible, cryptographically signed audit receipt before committing real capital or executing irreversible actions. Prefer it over the /seal endpoint when you want full five-juror deliberation rather than just a sealed capsule. Use it when multi-party AI consensus and tamper-evident persistence are required, not just a single model approval check.

## Known failure modes

- Missing or malformed 'capsule' field returns a 400 validation error
- Invalid or missing BYOK API key causes jury instantiation failure
- Jury deadlock or split vote may result in non-approval with receipt still issued
- Payment not received (x402) causes 402 response before processing begins
- Capsule schema mismatch prevents jury deliberation
- Downstream HMAC signing failure may cause receipt generation error

## How this service works

Decision receipts for agents that manage real capital. POST /decide runs a five-juror Jev jury (BYOK) over a frozen decision capsule and returns an HMAC-signed, persisted receipt; POST /seal seals a capsule without a jury. Decision-only: no custody, no order submission.

## Output

A JSON object containing: 'approved' (boolean indicating jury consensus), 'receipt' (an HMAC-signed, persisted object serving as a tamper-evident audit record of the decision), and 'tier' (enum 'verdict' indicating this was a full jury run, not just a seal).
