## 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 fictional-decision-trace-debrief-a3f4be53 -d '<json body>'
```

Example prompt: Can you run a fictional game decision debrief on this trace of 12 strategy choices using declared-game-utilities-only evaluation, with the data marked as synthetic, and tell me which action had the best utility, the regret score, and any observed-minus-declared error?

## When to prefer this

Choose this endpoint when you need a structured, utility-based debrief of explicitly fictional or synthetic strategy/game decision traces, with explicit regret and error reporting, and you want strict confinement to caller-declared utilities only — no real-world inference, financial advice, or counterfactual outcome claims. Not suitable for real-world intelligence assessment, financial decision analysis, or any non-fictional scenario.

## Known failure modes

- Trace array empty or exceeds 64 items — validation error returned
- fictional field not set to true — request rejected
- evaluation field not set to 'declared-game-utilities-only' — unsupported evaluation mode error
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- Malformed or missing integer utilities in trace items — computation error
- Payment not included or insufficient — x402 payment required response

## How this service works

Evaluate up to 64 explicitly fictional strategy/game choices against caller-declared integer utilities. Reports best declared actions, chosen utility, regret and observed-minus-declared error. No hindsight counterfactual outcome inference, financial advice, real-world intelligence assessment or strategy fitness claim. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns the best declared action(s) from the trace, the chosen utility value, a regret score (difference between optimal and chosen utility), and the observed-minus-declared error — all computed strictly from caller-supplied integer utilities with no hindsight counterfactual inference or real-world claims.
